摘要:
The present invention has for an object unsymmetrical naphthalene derivatives of formula (I) and agents containing these compounds for coloring keratin fibers or agents for coloring and simultaneously brightening keratin fibers wherein A1 and A2 are different and independently of each other represent partial structures of formulas (II), (IIIa), (IIIb), (IV), (V) or (VI);

The present invention has for an object brightening cationic naphthalene dyes of formula (I) and colorants for keratin fibers, particularly human hair, containing these compounds
摘要:
The agent for coloring keratin fibers, especially human hair, contains at least one common cosmetic additive; an oxidant, such as hydrogen peroxide; and at least one naphthalene derivative of formula (I): wherein A1 and A2 are different from each other and, independently of each other, each denote a partial structure of formula (II), (IIIa), (IIIb), (IV), (V), or (VI): E is O or S; Y is N or a quaternary nitrogen atom substituted with a C1-C6-alkyl group, a C2-C4-hydroxyalkyl group, or a C4-C6-polyhydroxyalkyl group. New naphthalene derivatives are also described.
摘要:
The instant disclosure generally relates to a dual component hair coloring composition for coloring mammalian or synthetic keratin fibers, the composition comprising composition A comprising a cationic polymer, pigment microparticles and an aqueous medium, and comprising composition B comprising an anionic polymer, aqueous medium and optional cross linking agent. Optionally or alternatively composition B may contain pigment particles. The cationic and anionic polymers are at least partially soluble in the medium and the pigment microparticles are dispersed therein. The hair coloring composition forms a dual layer coating upon application to keratin fibers such as hair and has a substantially permanent pigment lastingness following development (setting); minimally alters the keratin fibers, upon application; and substantially eliminates development time. Methods of using such compositions are also described herein.
