Abstract

An oxidation hair dyeing agent composition provides a color tone for dyed hair which is not easily affected by repeated washing with cold and hot water containing shampoo and soap, and it has superior wash resistance. The oxidation hair dyeing agent composition is characterized as containing a cyclic silicone and a silicone elastomer. As a two-component type oxidation hair dyeing agent composition, it contains as the first component a mixture of an oxidation dye precursor, a cyclic silicone, a silicone elastomer, an emulsifying agent, and water. The mixture is emulsified in water using the emulsifying agent. The second component of the composition is an aqueous hydrogen peroxide solution.

Claims

1. An oxidation hair dyeing agent composition comprising a mixture of an oxidation dye precursor, a cyclic silicone, and a silicone elastomer, the silicone elastomer being an elastomeric polymethylsiloxane obtained by crosslinking wherein the content of cyclic silicone and silicone elastomer vary between 0.01-10% by weight based on the total weight of the hair dyeing agent composition.

2. The composition according to claim 1 in which the oxidation dye precursor is a compound selected from the group consisting of p-phenylenediamine, p-nitro-o-phenylenediamine, p-chlor-o-phenylenediamine, p-nitro-m-phenylenediamine sulfate, toluene-2,5-diamine, toluene-3,4-diamine, toluene-2,5-diamine sulfate, 2,4-diaminophenoxyethanol chloride, p-aminophenol, p-methylaminophenol, m-aminophenol-o-aminophenol, 5-(2-hydroxyethylamino)-2-methylphenol, aminonitrophenol, 4,4′

3. The composition according to claim 1 wherein the mixture is emulsified in water using an emulsifying agent.

4. A method of dyeing hair comprising applying to hair the composition according to claim 1.

5. A two-component oxidation hair dyeing agent composition comprising as the first component a mixture of an oxidation dye precursor, a cyclic silicone, a silicone elastomeric polymethylsiloxane obtained by crosslinking wherein the content of cyclic silicone and silicone elastomer vary between 0.01-10% by weight based on the total weight of the hair dyeing agent composition, an emulsifying agent, and water, the mixture being emulsified in water using said emulsifying agent;
