Basic info

Description D4
Status Submitted
Submitter United Kingdom
Details on the scope of restriction Wash-off personal care products in the EU shall not contain more than 0.1% of D4, nor more than 0.1% of D5.
Further substance information EC Number: (D4) 209-136-7 (D5) 208-764-9; CAS Number: (D4) 556-67-2 (D5) 541-02-6
Reason for restriction D4 and D5 are two siloxanes that have PBT (D4) and vPvB (D5) characteristics. Each has a range of generally similar uses. A particular concern is the release of these substances into freshwater and their subsequent persistence and build-up in sediments, followed by bioaccumulation through the food chain. One significant use that results in emission of these substances into water is via their presence in wash-off personal care products. A restriction of this use would make a significant contribution to reducing their presence in water sediment. This targetted approach would be more appropriate than alternative regulatory approaches that would be less targetted and would encompass numerous other use situations of lesser concern.
