Data sought by European Commission on nano ingredients in cosmetics by Nick Boley

The European Commission has asked for more detailed toxicity data on three nano ingredients which are quite commonly used in cosmetics.

The three substances are:

  • nano collodial silver;
  • nano styrene/acrylates copolymer; and
  • nano sodium styrene/acrylates copolymer.

Nano colloidal silver is used as an antimicrobial, has a lowest cut off particle size of 1 nm and a maximum concentration up to 1.0 % in cosmetic products. Although the toxicity data needs to be more detailed, there is still a difficulty in accurately characterising and measuring the concentration of nano-colloidal silver, with robust validated methods not being available.

Similar problems exist for the nano-forms of the two copolymers.
