Basic Brown 17 ●
TL;DR. This ingredient is a synthetic cationic direct dye used to deposit it color in hair-color products. It binds to the negatively charged hair surface without needing an oxidizing developer.
What does Basic Brown 17 do in a cosmetic formula?
This ingredient is a synthetic cationic direct dye used to deposit it color in hair-color products. It binds to the negatively charged hair surface without needing an oxidizing developer.
Is Basic Brown 17 clean?
This ingredient has clean-standard friction because it is a synthetic hair colorant with sensitization, staining, and regional restriction considerations. It is more likely to appear in conventional hair-color systems than in minimalist or natural-positioned formulas.
Is Basic Brown 17 sustainable?
This material is typically made through petrochemical dye chemistry rather than renewable sourcing. Like many synthetic cationic dyes, it can show limited biodegradability and higher aquatic persistence concerns than simpler biodegradable ingredients.
Is Basic Brown 17 COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic standards for cosmetic colorants. From a Green Chemistry view, it has weaker fit because it is synthetic, non-renewable in typical sourcing, and not known for ready biodegradability.
How does Basic Brown 17 work chemically?
The molecule is a positively charged aromatic colorant, which explains its substantivity to keratin and its use in direct-deposit hair color. It is commonly used at low levels, often below about 2% where permitted, and formulation compatibility is best in systems that do not strongly complex or precipitate cationic dyes.
