Abstract
Disclosed are methods, kits and compositions for coloring the hair involving a color base composition having: at least one oxidation dye precursor, and at least 5% by weight water based on the weight of the color base composition, wherein the color base composition has a pH ranging from 2 to 12; and a developer composition made from a combination of an anhydrous oxidizer composition containing at least one oxidizing agent chosen from persulfates, perborates, percarbonates, their salts, and mixtures thereof, and a shampoo composition containing a carrier vehicle and at least 4% of at least one surfactant.
Claims20
A method of permanently coloring hair, comprising the steps of
- (a) providing a color base composition containing.
- (iii) at least one primary dye intermediate chosen from ortho-aminophenols, para-aminophenols, oho-phenylenediamines , para-phenylenediamines, double bases, heterocyclic bases, the acid addition salts thereof, and mixtures thereof;
- and
- (iv) at least 5% by weight of water, based on the total weight of the color base composition, wherein the color base composition has a pH ranging from 2 to 12;
- (b) applying the color base composition onto the hair;
- (c) rinsing the color base composition from the hair;
- (d) providing an anhydrous oxidizer composition containing at least one oxidizing agent chosen from persulfates, perborates, percarbonates, their salts, and mixtures thereof;
- (e) providing a shampoo composition containing a carrier vehicle and at least 4% by weight, based on the total weight of the shampoo composition, of at least one surfactant chosen from anionic, amphoteric, nonionic, zwitterionic, cationic surfactants, and mixtures thereof;
- (f) combining (d) and (e) immediately prior to use, to form a developer composition, wherein the developer composition contains from 1% to 80% by weight of the oxidizing agent, based on the total weight of the developer composition;
- (g) applying the developer composition onto the hair in order to develop color, in situ, to form colored hair;
- and
- (h) rinsing the developer composition from the hair.
A kit for coloring a keratinous substrate comprising:
- (a) a multi-unit receptacle;
- (b) at least one unit comprising a color base composition, the color base composition containing:
- (i) at least one primary dye intermediate chosen from ortho-aminophenols, para-aminophenols, ortho-phenylenediamines, para-phenylenediamines, double bases, heterocyclic bases, the acid addition salts thereof, and mixtures thereof;
- and
- (ii) at least 5% by weight of water, based on the total weight of the color base composition, wherein the color base composition has a pH ranging from 2 to 12;
- and
- (c) at least one unit comprising an anhydrous oxidizer composition containing at least one oxidizing agent chosen from persulfates, perborates, percarbonates their salts, and mixtures thereof;
- and
- (d) at least one unit comprising a shampoo composition containing a carrier vehicle and at least 4% by weight, based on the total weight of the shampoo composition, of at least one surfactant chosen from anionic, amphoteric, nonionic, zwitterionic, cationic surfactants, and mixtures thereof.
