Scientific Committee on Consumer Safety (SCCS) opinion on Cyclomethicone

SCCP concluded in its opinion (SCCP/0893/05) adopted during the 6th plenary meeting of 13 December 2005 that "On the basis of provided data, the SCCP is unable to assess the risk to consumers when Octamethylcyclotetrasiloxane (D4) is used in cosmetic products.

Despite the size of the dossier submitted by industry for evaluation, it is unfortunate that the dossier lacked meaningful information/data on actual consumer exposure to D4. The following information is required before any further consideration:
-  Adequate information on the use of D4 in cosmetics, in particular in different cosmetic products;
 -  Relevant/appropriate percutaneous absorption studies at different use concentrations;
 -  Information on the co-use, and hence consumer exposure, of related organosiloxanes,in particular decamethylcyclopentasiloxane (D5). "
