3. Results and Discussion
SCCS opinions are currently organised into hair dyes, cosmetics ingredients and nanomaterials; but over the period evaluated in the present study, the opinions were organised into fragrances, hair dyes, preservatives, UV-filters and other substances. In this paper, for comparative purposes, we distinguish between hair dyes and other ingredients, but we have also grouped the two categories together. The number of SCCS opinions depends on the type of cosmetics; hair dyes were the most numerous with 75 substances evaluated.
