VigilNanos - The ban on TiO2 in food (E171)

The ban on TiO2 in food (E171)


Ban on TiO2 in food (E171) – chronology and current situation

By AVICENN Team – Last Added January 2023

This page compiles information about theprohibition of the additive E171 (titanium dioxide, partially nanoparticle, used in particular in food as a white dye or varnish). This ban, in force in France since 2020, in Europe since August 2022 (and in Switzerland from September 2022) is the result of collective work and contributions from NGOs (supported by AVICENN), scientists, media, parliamentarians and public authorities.

To note :

  • Most French manufacturers and distributors did not wait for the law to withdraw TiO nanoparticles2 and/or the E171 of their products.
  • To learn more about risks associated with ingesting titanium dioxide nanoparticlesclick here.
  • Many voices are raised to ask for theban on titanium dioxide in medicines and toothpastes.

In 2022,

  • December 23, 2022: The suspension of the marketing of foodstuffs containing E171 has been renewed for 2023 in France by the decree of December 23, 2023. It makes it possible to prevent the disposal on French territory of stocks placed on the European market, whereas the European ban implemented in August 2022 does not provide for any specific withdrawal measure for these foodstuffs.
  • 14 December 2022: ANSES published its opinion on the risk assessment of the nanometric fraction of the food additive E171 which points to the lack of toxicological data available to carry out a complete assessment of the additive E171 and recommends limiting the uses and exposure of workers and consumers to nanomaterials, “by promoting the use of safe products, devoid of manufactured nanomaterials, and by limiting these uses to those ultimately considered to be duly justified and subject to a documented demonstration of the acceptability of the risk”.
  • September 21, 2022: A review of the scientific literature published in the journal Nanomaterials, carried out on nearly 800 scientific articles by a research team in Portugal, concluded on the merits of banning titanium dioxide nanoparticles in food.
  • August 8, 2022: From today, foodstuffs containing E171 can no longer be placed on the European market. Under the European regulation 2022/63 of January 14, 2022 prohibiting the food additive titanium dioxide (E171), those that had been previously can remain so until their date of minimum durability or their expiry date.
  • July 2022: In the United States, the media (The GuardianThe Washington PostLos Angeles Timesthe New York Times, etc.) relay the complaint (seeking to be considered a class action) trademark by a consumer in federal court for the Northern District of California against the company Mars, which continues to market Skittles candy containing E171, even though the company undertook to withdraw it of its products in 2016 (and that it has removed from M&M's in France). Titanium dioxide as a food additive is currently still authorized by the Food and Drug Administration (FDA).
  • June 23, 2022: A Guardian article titled “Food additive or carcinogen? The growing list of chemicals banned by EU but used in US » points out the lesser protection of Americans compared to E171, soon banned in the European Union but still considered safe in the United States.
  • June 21, 2022: Following theEFSA opinion on the E171, the European Commission has required the Scientific Committee for Consumer Safety (SCCS) to reassess the safety of TiO2 in cosmetics, in view of its genotoxicity when exposed by inhalation and by the oral route. Among the types of cosmetics mentioned: lip balms, lipsticks, toothpastes, powders and sprays. The CSSC has nine months to issue its opinion, which should therefore be finalized in March 2023.
  • March 9, 2022: In Switzerland, the Federal Office for Food Safety and Veterinary Affairs (FSVO) announcement the ban on the use of titanium dioxide as a food additive from March 15, 2022, accompanied by a transitional period of six months (foodstuffs may still be produced and marketed according to the old law until September 15 2022; after this date, they can be given to consumers until the expiry of the expiry date).

In 2021,

  • November 30, 2021: The Implementing Regulation (EU) No. 2021/2090 of 25 November 2021 concerning the "refusal of authorization of titanium dioxide as a feed additive for all animal species" was published in the Official Journal of the European Union (OJEU). It stipulates that the authorization of titanium dioxide (E 171) as an additive in animal feed from the category of “sensory additives” and from the functional group of “colorants” is refused. Existing stocks and premixtures containing it must be withdrawn from the market by 20 March 2022 at the latest. Feed materials, as well as compound feed produced with the additive or premixtures must be withdrawn from the market no later than June 20, 2022.
  • October 8, 2021: Member states have approved a ban on titanium dioxide in food across the European Union. The text should come into force at the beginning of 2022. A 6-month phase-out period will then begin, after which the total ban on E171 in food products will apply. This decision was voted by the Standing Committee on Foodstuffs (CPVADAAA), on a proposal from the European Commission, following the scientific opinion of the European Food Safety Authority (EFSA) concluding that E171 can no longer be considered as safe as a food additive (see below). This news was applauded by the NGOs that worked for this ban (in particular, Acting for the Environment and FoodwatchWECF at the French level, the BEUCCEO and HEAL or even SAFE at the European level). More informations here.
  • June 9, 2021: The “Rappel Conso” site today publishes a alert on Leader Price sugar-free sugar-coated chewing gums which contain the additive E171 banned for sale in France, due to the potential risks of colorectal cancer associated with the ingestion of titanium dioxide (partly in the form of #nanoparticles).
  • 31 May 2021: Four MEPs (Maria Arena (S&D), Martin Hojsík (Renew), Mick Wallace (The Left), Anja Hazekamp (The Left)) have asked the European Commission to respond to four questions following:
    • When does it intend to publish its proposal and on what date will the examination of this proposal begin?
    • What is the timetable for the discussion and adoption of the proposal, "given the importance of introducing the ban as soon as possible in order to prioritize the health and safety of people in the European Union" ?
    • Does the Commission intend to restrict the additive E171 to non-food use, including medicines and cosmetics?
  • May 18, 2021: During the meeting of a CPVADAA working group, EFSA presented its opinion on E171 to the Member States and the European Commission its proposal to ban E171 in Europe; the member states will meet again after the summer to vote on the timetable for the entry into force of the ban – with a right of scrutiny from the Council and the European Parliament then, necessary before the final adoption of the ban.
  • May 10, 2021: A few days after the announcement of the upcoming ban on E171 in Europe, three substitutes for E171 are mentioned in a Article by FoodIngredients1st : with what guarantees concerning their harmlessness? :
  • May 6, 2021: The European Commissioner for Health and Food Safety, Stella Kyriakides, has announced that the European Commission was going to propose a European ban on E171 ; this announcement was made just hours after the publication of thereview from the European Food Safety Agency (EFSA) concluding that this additive can no longer be considered "safe", due to potential genotoxic effects (DNA damage). This is a very clear change in the position of the EFSA, which until now had made every effort to say that E171 was "safe" - and this, despite the numerous scientific publications which accumulate for several years and show adverse effects. This reversal confirms the relevance of the alerts launched - for more than ten years now - by scientists and associations and taken seriously by the French authorities, who have suspended E171 since 2020! See below.
  • January 26, 2021: The Arte documentary The Great Junk Food looks back on the suspension of E171, with some of the associative, scientific, institutional and industrial players who played a decisive role in this file:

In 2020,

  • December 23, 2020: Publication in the Official Journal of of December 21, 2020 “suspending the marketing of foodstuffs containing the additive E 171 (titanium dioxide – TiO2)”:
  • October 8, 2020: The European Parliament, meeting in plenary, voted, by an overwhelming majority, overwhelming majority, the objection lodged by several MEPs against the European Commission's proposal to authorize E171 additives which contain up to 50% titanium dioxide nanoparticles.
  • May 26, 2020: The European Commission has proposed to ban E171 additives that contain more than 50% nanoparticles. France is theoretically not affected by this measure since E171 is no longer authorized on French soil since January 1, 2020 – at least in food (drugs would be concerned). But the other Member States have just approved this Community framework which they have been waiting for for a long time. Their vote still needs to be confirmed by the European Parliament and Council this summer. Such a measure raises several questions, in particular on the 50% threshold retained – unrelated to any health consideration. Learn more here.
  • May 15, 2020: A review of the scientific literature carried out by CEA researchers shows that particles of titanium dioxide (TiO2), of nanometric size and microscopic, lead to DNA damage on various cell types, including intestinal cells, even at low and realistic doses. Learn more here.
  • January 13, 2020: According to a report of the CPVADAAA meeting* of 19 December 2019 by the Dutch government, the European Commission would have affirmed "to respect the French measure" but without having the intention of extending it to the rest of the European Union. As previously mentioned, the Commission is awaiting the next EFSA opinion scheduled for the end of 2020 and will continue its work on the specifications concerning the particle size distribution of E171 and the limitation of heavy metals.
  • January 1, 2020: The suspension of the food additive E171, composed of (nano)particles of titanium dioxide comes into force in France. In one press release published a few days earlier, the Agir pour l'Environnement association welcomed this "historic and courageous decision" and stressed that manufacturers and distributors had already largely anticipated this suspension: today there are hardly any products containing E171 in France. A "new proof of the uselessness of this additive" according to the association, which recalls at the same time its wish that this suspension of titanium dioxide be "extended to all products likely to be ingested" (toothpastes and medicines) , in view of the dangerousness of the additive confirmed by scientific studies compiled by AVICENN.

In 2019,

  • December 17, 2019: 34 Members of the European Parliament (Belgian, Croatian, Greek, Irish, Italian, Luxembourgish and French) have écrit to European Commissioner for Health Stella Kyriakides for him ask to ban E171 in products sold in Europe due to health risks.
  • December 2, 2019: Following theemission of RTS on nanoparticles in foodthe European Chemical Industry Council (CEFIC) wanted to provide "precision" published on the show's website according to which "EFSA has confirmed the absence of risk attached to the additive" [Editor's note: a particularly biased interpretation of the EFSA opinion of which CEFIC does not relay the mentions relating to the uncertainties nevertheless underlined by the European Food Safety Agency], that “other studies conducted in accordance with OECD guidelines have not demonstrated adverse effects” and that "the Food and Environment Research Agency in the United Kingdom, the Tübitak Marmara Research Center in Turkey and the Institute for Food Safety (RIKILT) in the Netherlands have conducted a study on the oral consumption of nanometric particles and in particular titanium dioxide. This study did not reveal any significant risk from exposure to nanoparticles.This study dates from 2015. And CEFIC does not mention the numerous studies published since, which themselves report worrying effects.
  • November 19, 2019: Nanoparticles in food are on the menu of "A Bon Ententeur", the Swiss reference program in terms of consumption, entitled this evening: “E171, E551… would you take some additives? » Among the organizations questioned in France: LNE, INRA Toulouse, Agir pour l'Environnement and AVICENN:
  • November 22, 2019: In reply to the request from MEP Eric Andrieu to extend the ban on E171 to all of Europe, Mr. Andriukaitis, European Commissioner for Health and Food Safety of the Juncker Commission, states that the European Food Safety Authority (EFSA) considers that "the use of titanium dioxide as a food additive is safe based on current scientific knowledge" and that "ongoing toxicity testing, which is expected to be completed by July 2020, will further reduce the remaining uncertainties". The Commission is considering the next steps. Learn more here.
  • November 4, 2019: La petition launched by the NGO SAFE (Safe Food Advocacy Europe) in partnership with Agir pour l'Environnement and ECOS to call for a ban on E171 at European Union level has exceeded 80 signatures
  • October 17, 2019: The E171 was on the agenda of the dossier on nanoparticles from the program "La Quotidienne" on France 5, with Danielle Lanquetuit from VICENN and Francelyne Marano from Paris-Diderot University. The show is available replay here.
  • September 30, 2019: The Foodwatch Association Netherlands announcement, in press release in dutch, what several brands he promised to remove E171 from their food products: Remia, Mora, Mars, Goodbite, Lindt, Haribo and A.Vogel following the recommendations issued on August 21 by the Office for Research and Risk Assessment (BuRO) of the Dutch Ministry of Food aimed at reducing consumer exposure to E171.
  • September 26, 2019: The French suspension of the E171 was still in theagenda for a CPVADAAA meeting*. Member States again expressed their preference for a harmonized approach at European level, based on the next EFSA opinion expected in July 2020. (See the minutes of the session)
  • September 26, 2019: The press release in which Michigan State University presents its study minimizing the effects of the additive E171 title on the “premature” nature of the French suspension of the E171. He claims that INRA researchers (whose 2017 publication had received a great deal of attention from the media and the public authorities) did not use a control group (called “DMH alone”) in their carcinogenesis experiments, which is false, this group being part of the results. Two weeks earlier, the American study in question had been singled out by a coalition of associations, questioning its scientific rigor and its independence.
  • September 16, 2019: The French E171 ban was on the agenda of an expert meeting in Brussels. Like last May, the vast majority of Member States are in favor of a harmonized measure at European level, based on the next EFSA opinion expected in July 2020. Several associations had previously asked their governments to support the French measure and encouraged the European Commission to remove E171 from the list of authorized additives, such as Purchasing test in Belgium. A petition in english was launched by the NGO Safe Food Advocacy Europe (SAFE). Conversely, the manufacturers or companies using E171 lobby the authorities to oppose any restriction of this additive, as evidenced for example by the joint letter from German trade associations for food, chemicals, dyes and drugs to the German Ministry of Food, Agriculture and Consumer Protection sent shortly before the meeting.
  • September 12, 2019: Several NGOs react following the publication of a American study minimizing the risks of the controversial additive E171, fifteen days before a meeting in Brussels which examines the French ban on E171. Building on first disturbing elements recorded by AVICENN (unexplained “obscured” colon samples, almost doubling of colorectal cancer markers deemed “not significant” by the authors), Acting for the Environment, Health and Environment Alliance (HEAL), Foodwatch, Center for International Environmental Law (CIEL), Safe Food Advocacy Europe, European Environmental Citizens' Organization for Standardization (ECOS) question* the scientific rigor of the'study funded by three industrial federations reluctant to see the removal of E171 (the federation of TiO2 manufacturers (TDMA), the federation of dye manufacturers (IACM) and the trade federation (GMA)) . * To see the inter-associative press release (English)
  • August 21, 2019: The Office of Research and Risk Assessment (BuRO) has published a review in which he recommends that the Dutch Ministry of Food discuss with manufacturers in order to reduce exposure to E171, to examine the presence of titanium dioxide in other products (in particular medicines), to improve research on the link between E171 and colorectal cancer.
  • July 11, 2019: Several of the signatory NGOs of the interassociative letter sent at the beginning of May to the European Commission were received by the latter in order to discuss the possibilities of extending the French suspension of the E171 to the entire European Union.
  • July 5, 2019: The spanish magazine OCU-Compra Maestra revealed that the E171 and E551 contained in all of the 8 food products tested by the Spanish consumer association “Organización de Consumidores y Usuarios” (OCU) contain nanoparticles, in varying proportions (ranging from 27 to 76% for the 4 products containing E171, 100% for the 4 products containing E551), without mention [nano] on the packaging, contrary to the regulationsThe consumer association OCU demands the re-evaluation of these additives.
  • June 2019: The belgian magazine Health test n°151 devotes five pages to nanomaterials; he reveals that the E171 contained in the 6 food products tested contain nanoparticles, in varying proportions (ranging from 7 to 80%), without mention [nano] on the packaging contrary to regulations. And requests the suspension of the marketing of E171 in Belgium (among other additives).
  • May 29, 2019: The French suspension of the E171 is approved up to the USA by of  researchers interviewed by The Guardian they are also worried about the health effects induced by nanoparticles in food.
  • May 23, 2019: In Italy, the consumer association Altroconsumo publishes the results of tests carried out on food products, which show high levels of nanoparticles in the food additives E171, E174 (silver) and E551 (silica) but not indicated on the label. The association not only asks for the suspension of the E171 but also theapplication of the precautionary principle for other nanoparticle additives.
  • May 9, 2019: In turn, the Léo Lagrange Association – Consumer Defense (AALDC) publicly regrets "the policy of small steps" of the government concerning the suspension of the E171, in particular the limitation of its scope to only food products sold in France, the late date of the entry into force of the text, as well as the tolerance towards manufacturers with regard to the disposal of stocks.
  • May 3, 2019: In a mail sent todaysome forty European associations have asked the European Commission to extend the suspension of E171 to the entire European Union (and at the very least, not to cancel the measure in France).
  • April 25, 2019: Publication in the OJ ofOrder of 17 April 2019 suspending the marketing of foodstuffs containing the additive E 171 (titanium dioxide – TiO2)
  • April 19, 2019: The Federation of Titanium Dioxide Manufacturers (TDMA) regrets France's decision to suspend the E171. The questionable scientific argumentation is coupled with economic considerations, no doubt more in line with the interests of the federation: the fear of a “fragmentation and disruption of the European single market”.
  • April 1, 2019: The MEP Guillaume Balas (from the Génération.s movement) has published on his website the European Commission's response to the written question on the E171 which he asked in January: the European Commission "Considers that there are currently no grounds for applying precautionary measures with regard to the authorization of titanium dioxide as a food additive". An answer that the deputy judges “not up to the health challenge. In application of the precautionary principle, the Commission has the possibility of withdrawing from the market a product which may pose a potential danger to the health of European citizens. It is therefore a choice on the part of the Commission to limit its action and to prefer the economic interests of companies to the health of citizens.« . Guillaume Balas says he will continue his battle "to update this hypocrisy and protect the health of Europeans”.
  • March 28, 2019: The Association Acting for the Environment was received by the office of the Minister of Economy and Finance, Bruno Le Maire, to whom she requested the expansion of the titanium dioxide suspension (expected in the feed in mid-April) to all products that can be totally or partially ingested: toothpastes and medicines in particular. Ministry officials reportedly ruled out extending the scope of the order to products other than food, but confirmed that the suspension of titanium dioxide in food will be taken in mid-April, following the publication of ANSES's opinion. More details here.
  • February 6, 2019: According to the Official Journal, the Government's report to Parliament on the measures taken concerning the import and marketing, free of charge or against payment, of any foodstuff containing titanium dioxide as a food additive (E 171) and consumer uses was forwarded to the Economic Affairs Committee and the Senate's Regional Planning and Sustainable Development Committee.
  • January 21, 2019: ANIA, which represents the food industry in France, calls “Regulatory Frexit” the unilateral suspension of E171 envisaged by the French government, which "discredits the European authorities, suggesting that Europe is lax and inefficient on health issues". ANIA nevertheless recognizes that the time has come to simplify recipes, with shorter lists of ingredients and the elimination of non-essential food additives – concerning E171, the procedures for elimination or substitution are already - already committed (the substitution is however complex, expensive, it cannot be done overnight (and the alternatives must also be evaluated).
  • January 11, 2019: Nth twist in the soap opera concerning the suspension of the E171: Bruno Le Maire finally engaged to sign the decree suspension of the E171 by April 15! The 22 signatories of the column published in Le Monde in December were invited to a meeting in Bercy at 14:30 p.m. in the presence of Bruno Le Maire. The minister acknowledged mistakes in the management and communication of this file and recognized the need to implement the precautionary principle to protect public health. The associations present - including Agir pour l'Environnement, CLCV, foodwatch, France Nature Environnement, Générations Futures, Citizen Sciences, Léo Lagrange, UFC Que Choisir, 60 million consumers - welcome this clarification from the Minister, even if they regret that this suspension takes another three months. To relive and follow on Twitter.
  • January 10, 2019: MP Delphine Batho indicated this afternoon on his twitter account having asked that Minister Bruno Le Maire, who refuses to apply the law, be summoned before the competent committees of the National Assembly. In addition, the arbitration concerning the suspension of the E171 would "not yet be completed" according to Agir pour l'Environnement, who met the cabinet of François de Rugy at the end of the afternoon. These words reported by The Journal of the Environment nuance the picture: the interministerial arbitration is apparently not yet folded.
  • January 9, 2019: Following Bruno Le Maire's announcement not to suspend the E171, reactions are pouring in. AVICENN relays them on the Veillenanos twitter account and will compile them soon on this site. To be continued then…
  • January 8, 2019: The Minister of the Economy Bruno Le Maire confirmed this evening in the program "C à vous" on France 5 that he did not intend to sign the suspension order for titanium dioxide (nano)particles in food (additive E171) before long months (or even more: he wants to wait for ANSES's opinion, and then request a new referral from EFSA, etc.). This response confirms the information we gathered during the ANSES dialogue committee on November 26, those relayed by APM news on December 26 (which invoked as a reason that the ministry could not go against the European Commission) followed by a article from Europe 1 of January 2, where one could read that the ministry went so far as to say that "Now it's up to the consumer to be careful".

In 2018,

  • December 24, 2018: In a column published in today's Le Monde, 22 organizations are calling on Minister Bruno Le Maire to make the suspension of the food additive E171 effective as soon as possible., composed of titanium dioxide (part of which in the form of nanoparticles). Despite a strong commitment from the government and parliamentarians, Bercy is carrying out a blockage deemed unacceptable by the co-signatories, who are demanding the application without further delay of this important public health measure. . At the announcement of this information, the deputy Matthieu Orphelin immediately reacted on Twitter : “Article 53 of the #EGalim law is however clear: suspension of the E171 additive and report to parliament before January 1, 2019 on the proper implementation of this decision. Let's not go back ».
  • November 26: Contrary to the official position of the French authorities, the DGCCRF indicated that it did not intend at this stage to draft the decree implementing the suspension of the E171, on the grounds that the evidence of "serious or immediate danger" had not yet been made. This assertion contradicts the government's commitment in the spring, confirmed by Parliament's vote in the autumn within the framework of the Food Law (this temporary ban is one of the rare measures applauded by the associations to have been retained in the version end of the law). This announcement by the DGCCRF was made during the ANSES "nano and health" dialogue committee, in which Avicenn and several other associations participated. More information provided, on request, to our members and associate members.
  • November 8: "Now that the law has been published in the OJ, do you have more information to communicate on the timetable and the content of the decree concerning the suspension of the E171 provided for by its article 53" ? This is the question that AVICENN asked the DGCCRF again (answer pending).
  • November 7, 2018: Fabrice Nesslany, from the Institut Pasteur, considers that "the usefulness (of E171) is so low, and with the doubts that may still remain today (...), it is useless, so while waiting for more consolidated studies, let's not use it » at a nano symposium at the Maison de la Chimie in Paris
  • November 2, 2018: Defense of Héloïse Proquin's thesis on the role of E171 in the development of colorectal cancer at the University of Maastricht in the Netherlands: “the classification of E171 as exempt from toxic effects due to its insolubility and its inertness is no longer valid (…); the presence of inflammation seen in animal models after ingestion of E171 could aggravate inflammatory bowel disease and its adverse effects on the development of colorectal cancer. Therefore, we recommend that experiments (…) emphasizing human testing, be performed for further evaluation of E171 on its potential adverse effects on cancer enhancement, immune system dysregulation and inflammation. These new data would provide information on the effects on humans for a complete risk assessment, which could lead to a modification of the use of E171 in food products: reduction of the amount of nanoparticles, fixation of a maximum level of use in food products, stricter limitation of the types of products in which it can be used, or even suspension of the product itself ”.
  • November 1, 2018: The Food law was published in the official journal: according to its 53 article...

... " The placing on the market of the additive E 171 (titanium dioxide-TiO2) as well as foodstuffs containing it is suspended, under the conditions provided for inarticle L. 521-17 of the consumer code and in article 54 of the Regulation (EC) No 178/2002 of the European Parliament and of the Council of 28 January 2002 establishing the general principles and general requirements of food law, establishing the European Food Safety Authority and laying down procedures relating to food safety. The Government shall submit, by 1 January 2019 at the latest, a report to Parliament on all the measures taken concerning the import and marketing, free of charge or against payment, of any foodstuff containing titanium dioxide as an additive. food (E 171) and consumer uses."
