Abstract
Abstract The dye carrier composition for oxidative dyeing of hair advantageously includes a combination of about 0.01 to 5 percent by weight of developer substance and about 0.01 to 5 percent by weight of coupler substance, from 0.1 to 10 percent by weight beeswax and from 0.1 to 10 percent by weight of one or more protein hydrolyzates and/or amino acids. The composition can also contain 0.1 to 30 weight percent of an non-ionic and/or anionic wetting agent or emulsifier and the protein hydrolyzates preferably include silk protein hydrolyzate and/or keratin hydrolyzate.

Claim 10
Independent Claim
150 words
A method for oxidative dyeing of hair, said method comprising the steps of: a) providing a dye carrier composition comprising a combination of about 0.01 to 5 percent by weight pf developer substance and about 0.01 to 5 percent by weight of coupler substance, beeswax and at least one ingredient selected from the group consisting of protein hydrolyzates and amino acids; b) mixing said dye carrier composition with an oxidizing solution immediately prior to application to provide a ready-to-use hair dyeing mixture; c) applying an amount of the ready-to-use hair dyeing mixture sufficient to dye the hair directly to the hair; and then d) after the applying of step c), allowing the ready-to-use hair dyeing mixture to act on the hair for a reaction time of 10 to 45 minutes at 15 to 50°C.; and e) after the allowing of step d), rinsing the hair and subsequently drying the hair.
