The UK's restriction dossier for octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) has been delayed. Although it way initially expected this month, the UK will not submit its restriction document to the European Chemicals Agency (ECHA) on the two cosmetic ingredients until Apr. 15, 2015.

ECHA called for evidence on D4 and D5 after it was found that the two ingredients were persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB). There is also concern that D4 and D5 release into freshwater, build-up in sediments and bioaccumulate through the food chain.

In its restriction dossier, the US is set to propose that wash-off personal care products in the EU shall not contain more than 0.1% of D4, nor more than 0.1% of D5. This information will provide an input into ECHA's development of an Annex XV restriction dossier.
