Request for Scientific Opinion for Nano Silica in Cosmetics

December 18, 2013

A request for scientific opinion on the safety of nano silica in cosmetics products is being done by the European Commission (EC), as these ingredients are not regulated in Cosmetic Regulation (EC) No. 1223/2009.

The 2009 regulation has defined nanomaterial as an insoluble or biopersistent and intentionally manufactured material with one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm.

The nano-silica materials involved are:

  • Silica (nano) CAS n.l 112945-52-5;
  • Hydrated Silica(nano) CAS n. 112926-00-8;
  • Silica Sylilate CAS n. 68909-20-6;
  • Silica Dimethyl Silylate (nano) CAS n. 68611-44-9
