Second part of the Safety Report: the aim here is to provide the exhaustive data allowing specifications, both for the ingredients and the finished product, and to provide information on the stability of the product.
The Annex I text quotes the data to provide:
• The physical and chemical characteristics of the substances or mixtures, as well as the cosmetic product
• The stability of the cosmetic product in reasonably foreseeable storage conditions
The raw materials specifications
The description of the physico-chemical characteristics must be made for each of the raw materials used in the product.
For everyone, all the relevant pieces of information shall be supplied:
• The chemical identity (INCI name, CAS number, EINECS number)
• The physical form
• The molecular mass
• For polymers, the median molecular weight and monomer content
• Solubility
• Purity (with eventually the nature and percentage of impurities)
• The partition coefficient
• For CMR, their nature and percentage
• For nanomaterials, the distribution curve of the particles after their size
• For UV filters, the absorption spectrum
• And any other relevant characterisation parameter
The references of the control methods shall be quoted for each specification.
An example of a specification sheet was presented by José Ginestar (Sisley) at the 10th Cosmetic Valley Perfumes & Cosmetics Congress.
