2. Methodology
The study material consisted of SCCS opinions issued between April 2008 and March 2013 concerning cosmetics ingredients. No confidential data were used, as all the information came from opinions downloaded from the Committee’s website. There are different types of opinions and in some cases there are addenda to previous opinions. In this study, only full opinions were considered: addenda or specific opinions for a particular item, such as microbial resistance, were not taken into account. Each opinion was analysed with respect to each of the different sections, taking note of whether the procedure used was based on the use of animals or non-animal models. The percentage of non-animal models was compared to that of animal models and the use of human data was also noted. A total of 103 dossiers were analysed: 75 corresponded to hair dyes and 28 to other ingredients in cosmetics including UV filters, fragrances and preservatives, among others.
