22 May 2024 --- The Official Journal of the European Union publication bans the use of cosmetic silicones octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5) and dodecamethylcyclohexasiloxane (D6) in wash-off and leave-on products. The restrictions add to those already imposed by REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) on rinse-off cosmetic products containing D4 and D5.
