Abstract
The aqueous or aqueous-alcoholic oxidative dye precursor composition includes 1,4-diamino-2-methoxymethylbenzene, or a physiologically compatible salt thereof, as developer substance and one or more conventional coupler compounds. A ready-to-apply hair dyeing mixture having a pH of 6 to 10.5 is made by mixing the aqueous or aqueous-alcoholic oxidative dye precursor composition with an oxidizing agent, such as 6% hydrogen peroxide in a weight ratio of 5:1 to 1:3. The compositions may also contain conventional cosmetic additive ingredients and direct-dyeing dye compounds.
Claims13
A ready-to-apply hair dye mixture made by a method comprising the steps of:
- a) providing an oxidation dye precursor composition containing at least one coupler compound and at least one developer compound, said at least one developer compound including at least one member selected from the group consisting of 1,4-diamino-2-methoxymethylbenzene and physiologically compatible salts of said 1,4-diamino-2-methoxymethylbenzene;
- b) mixing the oxidation dye precursor composition provided in step a) with an oxidizing agent immediately prior to application to form the ready-to-apply hair dye mixture.
An aqueous or aqueous-alcoholic oxidation dye precursor composition comprising water, at least one coupler compound and at least one developer compound, said at least one developer compound including at least one member selected from the group consisting of 1,4-diamino-2-methoxymethylbenzene and physiologically compatible salts of said 1,4-diamino-2-methoxymethylbenzene.
