Abstract
Abstract A coloring composition for dyeing keratinous material comprising water, an organic dye carrier, a premetallized dye soluble in the carrier, a stain-inhibiting agent and an anionic surface active agent. The dyes are premetallized dyes and the composition includes dye carriers, anionic surface active agents, and stain inhibiting agents in an aqueous solution. The composition is effective as a semi-permanent hair dye that can be applied to hair without staining the skin of the user.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
182 words
An aqueous hair coloring composition that is non-staining to the skin consisting essentially of: a. a major amount of water; b. from about 0.1 to about 10% by weight of a premetallized dye soluble in a compatible organic dye carrier and capable of penetrating keratinic fibers; c. from about 0.1 to about 10% by weight of a compatible organic dye carrier for coassisting the transfer of said dye into keratinic fibers, said dye carrier selected from the group consisting of: 1. a benzyl alcohol derivative selected from the group consisting of benzyl alcohols, C 1 -C 4 carboxylic acid esterified benzyl alcohol and benzyloxyalkanols; 2. an alkyl phenone; 3. an oxygen substituted cyclohexane selected from the group consisting of cyclohexanols and cyclohexanones; 4. n-nonylaldehyde; 5. 2-methyl-1-pentanol; 6. 2-phenoxy-ethanol; d. from about 0.1 to about 5% by weight of an anionic surface active agent; and e. from about 0.1 to about 5% by weight of a skin stain inhibiting agent selected from the group consisting of polyoxyalkylene (10 - 80) lanolins, lanolin alchols, lanolin fatty esters and C 8 -C 20 fatty alcohols.
Claim 2
Dependent Claim
