Titanium dioxide: E171 no lengthier deemed protected when made use of as a meals stuff additive

EFSA has up to date its protection evaluate of the meals additive titanium dioxide (E 171), following a request through the Eu Rate in March 2020. 

The up to date analysis revises the result of EFSA’s earlier evaluate revealed in 2016, which highlighted the need for extra analysis to fill information gaps.  

Prof Maged Younes, Chair of EFSA’s specialist Panel on Meals Components and Flavourings (FAF), stated: “Taking into consideration all to be had clinical research and knowledge, the Panel concluded that titanium dioxide can no for an extended time be considered secure as a foods additive. A vital part in attaining this conclusion is that we may just no longer exclude genotoxicity considerations after intake of titanium dioxide debris. After oral ingestion, the absorption of titanium dioxide debris is decrease, then again they are able to acquire within the frame”. 

The evaluate used to be carried out following a rigorous method and the usage of into account many numerous numbers of clinical exams that experience become accessible taking into consideration that EFSA’s former evaluate in 2016, together with new clinical proof and knowledge on nanoparticles. 

Our clinical professionals carried out for the primary time the 2018 EFSA Medical Committee Steerage on Nanotechnology to the fundamental protection analysis of meals components. Titanium dioxide E 171 is composed of at maximum 50% of debris within the nano vary (i.e. lower than 100 nanometres) to which consumers might be uncovered.  

Genotoxicity Evaluation 

Genotoxicity refers back to the talent of a chemical substance to hurt DNA, the genetic fabricated from cells. As genotoxicity would possibly smartly information to carcinogenic results, it is very important to evaluate the chance genotoxic have an effect on of a substance to conclude on its fundamental protection.  

Prof Matthew Wright, the 2 a member of the FAF Panel and chair of EFSA’s working workforce on E 171, stated: “Even though the evidence for not unusual destructive results used to be no longer conclusive, at the foundation of the brand new information and reinforced answers lets no longer rule out an issue for genotoxicity and as a result lets no longer create a secure degree for on a daily basis ingestion of the meals additive.”

Chance pros on the Eu Fee and in EU Member States were skilled of EFSA’s conclusions and can ponder right kind motion to take to make sure customers’ protection.


Titanium dioxide (E 171) is permitted as a meals additive within the EU in step with Annex II of Law (EC) No 1333/2008.  

The fundamental protection of the meals additive E 171 used to be re-evaluated through the EFSA ANS Panel in 2016 within the body of Law (EU) No 257/2010, as facet of the re-analysis programme for foods components permitted within the EU prior to 20 January 2009.  

In its 2016 perspective, the ANS Panel really helpful new experiments be performed to fill the gaps on doable effects at the reproductive process, which might allow them to established an Suitable Day-to-day Consumption (ADI). Uncertainty all over the characterisation of the content material hired because the meals stuff additive (E 171) used to be additionally highlighted, in sure with admire to particle measurement and particle size distribution of titanium dioxide used as E 171.   

In 2019, EFSA posted a statement at the evaluation of the likelihood attached to the exposure to meals pieces additive titanium dioxide (E171) achieved through the French Corporate for Meals stuff, Surroundings and Occupational Wellbeing Protection (ANSES). In its statement, EFSA highlighted that the ANSES influence reiterated the uncertainties and main points gaps previously recognized through EFSA and didn’t present findings that invalidated the Authority’s previous conclusions at the coverage of titanium dioxide.

In the very same calendar yr (2019), the Netherlands Meals and Shopper Product Safety Authority (NVWA) additionally shipped an influence on possible well being result of meals stuff additive titanium dioxide, which highlighted the good significance of inspecting immunotoxicological results along with potential reprotoxicological results.
