US Patent 8052762
Publication Date: Nov. 8, 2011
Assignee: Kelly Van Gogh LLC
Disclosed herein are compositions suitable for use in dyeing keratin-containing fibers. Further disclosed herein are colorant systems and compositions comprising the colorant systems. Also disclosed are kits comprising one or more colorant systems and an activator composition.
The colorant system comprises colorant precursors, optionally one or more active ingredients and optionally one or more diluents or carriers. In addition, an activator composition comprises one or more catalysts, optionally one or more active ingredients and optionally one or more diluents or carriers. The colorant precursor contains: approx. 0.5-25% w/w 1,4-phenylene-diamine; approx. 0.5-25% w/w 4-aminophenol; approx. 5-65% w/w 4-amino-2-hydroxy-phenol; approx. 2.5-40% w/w 2-nitro-N-(2-hydroxy-ethyl)aniline; approx 5-65% w/w 4-(3-hydroxypropyl-amino)-3-nitrophenol; and approx 5-65% w/w 1-hydroxyethyl-4,5-diamino pyrazole sulfate.
Additionally, the colorant system comprises approx. 0.2-1% w/w of one or more hair detangling agents chosen from C10-22 alkyl esters of alkoxylated trimethylolpropane, C10-22 alkenyl mono-ene esters of alkoxylated trimethylolpropane, C10-22 alkynyl mono-yne esters of alkoxylated trimethylol-propane, and mixtures thereof; approx. 0.005-0.05% w/w of one or more UV absorbers chosen from ethylhexyl methoxycinnamate (octyl methoxy-cinnamate), methoxydibenzoylmethane, polyoxypropylene, polyoxyethylene ethers of aliphatic alcohols, ethylhexyl salicylate and polyoxyethylene derivatives of hydroxy fatty acid containing fats and oils, and mixtures thereof; and approx. 0.1-1.5% w/w of one or more conditioning agents chosen from polyalkylene glycols, polypropylene glycols, polyalkylene glycol/polypropylene glycol copolymers.
