Proposed nanomaterial definition for cosmetics by Nick Boley

The European Consumer’s Union (beuc) has published a report entitled “Nano-materials in cosmetic products: definition needs to effectively protect consumers”. This report proposes ways to align the definitions of a nanomaterial in the EU cosmetic Regulations with that of the European Commission.
This is a sensible way forward. The Commission’s definition of a nanomaterial has been widely criticised in some quarters, but is seen by some as being relatively easily enforced, as the all the properties listed (particle size, number of nanoparticles, etc) are measurable, and anything the ability for properties to be accurately measured are, in my view, a pre-requisite to good legislation, regulation and enforcement.
Beuc believes that the alignment, which is needed for implementation of the nanomaterial requirements of the cosmetics Regulation in 2013, should:
– include all materials in which more than 0,15 % of the number of particles are present in the nano-size range;
– cover by-products which are not intentionally manufactured but which are present in the nano-range;
– include soluble nano-particles and nano-structures which have specifically been designed to carry encapsulated substances that will be released to the systemic circulation;
– include nano-particles below 1nm such as fullerenes;
– add a criterion on volume specific surface area as particle size distribution alone is insufficient to give information about the surface area which has an impact on the reactivity of the particles.
