SCCS: Completed Evaluation on New Hair Dye


The Scientific Committee on Consumer Safety (SCCS) has completed its evaluation on the safety of Hydroxypropyl p-phenylenediamine and its dihydrochloride salt, ingredients used in cosmetic hair coloring products. The thorough analysis has declared these compounds safe for use in oxidative hair dye products, provided that the maximum concentration on the scalp does not exceed 2%. This conclusion is based on the evidence provided and takes into account both consumer safety and existing regulations.



It was noted that during the evaluation, Hydroxypropyl p-phenylenediamine and its dihydrochloride salt have a potential for mild to moderate eye irritation. Furthermore, based on animal studies, these compounds are considered to have a moderate skin sensitization capacity.




These findings are crucial for understanding the potential risks associated with the use of these ingredients in hair coloring products and underscore the importance of following the safety recommendations provided by the SCCS.



SCCS's Rigorous Assessment


The SCCS's rigorous assessment highlights the committee's commitment to protecting the health and safety of European consumers, ensuring that ingredients used in cosmetics meet the highest safety standards in accordance with the EU Cosmetics Regulation (Regulation No. 1223/2009).


For those interested in a more detailed exploration of the SCCS's findings and conclusions, reviewing the official document available on the European Commission's website regarding the safety of Hydroxypropyl p-phenylenediamine and its dihydrochloride salt (SCCS/1659/23) is recommended.
