About
An anthraquinone-type blue dye used in cosmetics, subject to EU colorant approval requirements and general safety evaluation.
Solvent Blue 35 (CI 61554, CAS 17354-14-2) is an anthraquinone-type dye producing blue coloration. Anthraquinone dyes are generally considered safer than azo dyes in terms of aromatic amine concerns, as they do not readily cleave to release regulated aromatic amines. It is not listed in EU Cosmetics Regulation 1223/2009 Annex II restriction list, suggesting potential availability for cosmetic use. However, all cosmetic colorants must be individually approved under EU Cosmetics Regulation's positive list system. The dye is used in hair dye and decorative cosmetics applications. General requirements include purity standards and potential for sensitization at high concentrations.
Known concerns
- Must be individually approved as EU cosmetic colorant
- Contact sensitization possible at high concentrations
- Purity requirements for cosmetic use
