EU Reg Stands To Classify TiO2 As ‘Suspected’ Carcinogen Beginning Summer 2021
Reportedly, the Council of the European Union is considering member state objections and requests to extend the current scrutiny period beyond 4 December for a Commission delegated regulation that would classify titanium dioxide as a Category 2 carcinogen by inhalation. The move threatens to impact the marketing of sunscreens and other cosmetics in the EU that contain respirable TiO2 particles.

As of 5 February, the Scientific Committee on Consumer Safety is evaluating use of titanium dioxide – now officially classified as a Category 2 carcinogen in the EU – in cosmetic products that can expose consumers by way of inhalation. Without a favorable SCCS opinion, the ingredient’s use in those contexts will be banned under Article 15 of the Cosmetics Regulation.
TiO2's nano-form use in spray sunscreens is already prohibited in the EU under the Cosmetics Regulation, but broader restrictions potentially extending to other cosmetic categories could be imposed down the line following a proposal from ECHA's Committee for Risk Assessment that the ingredient be CLP-classified as a suspected carcinogen when inhaled. There are also potential ramifications stateside to consider.
Formed by the FDA in fall 2018 and convened in early 2020 for a public meeting, the Interagency Working Group on Asbestos in Consumer Products maintains that electron microscopy should be a first-line method for detecting asbestos in cosmetic talc and talc-containing products, and that labs should report elongate mineral particles beyond those classically understood as asbestos.
