Hair dye Basic Blue 99 and UV-filter Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate (S87): the safety of these two cosmetic ingredients will be assessed by the SCCS. The requests from the European Commission were published on November 8th, 2016.
Basic Blue 99
Background
The substance Basic Blue 99 (INCI) (CAS: 68123-13-7) (COLIPA No C059) with the chemical name 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl benzenaminium chloride is a direct hair dye substance in hair dye formulations with a concentration on-head of maximum 1.0%.
Submission I and II for the hair dye Basic Blue 99 were transmitted in August 1992 and March 2006 respectively by COLIPA. Following submission II, in September 2011 the Scientific Committee for Consumer Safety (SCCS) expressed concerns regarding the highly variable composition of Basic Blue of the analysed batches that led to the impossibility to conclude on the safety of the substance (SCCS/1437/11).
In reply to these scientific concerns, in July 2014 EFfCI provided new analytical data (Submission III) on the batches presented by COLIPA in the previous submissions, and on other more recent batches.
In September 2014, the SCCS concluded
that:
"Basic Blue 99 is a mixture of up to 40 substances of varying concentrations as demonstrated by the HPLC analysis of six batches. Due to the highly variable composition of Basic Blue 99 in six batches, the safety of Basic Blue 99 cannot be evaluated."
(SCCS/1537/14)
In April 2016, EFfCI submitted another dossier (Submission IV) containing new information on …
