Abstract
A low or no VOC hair lightener or dying composition with a low water content and a high organic content comprising: (a) a developer phase comprising: (i) water; (ii) an oxidizing agent; and (iii) optionally a thixotropic control agent; and (b) a tint phase comprising: (i) 0-50 weight percent water; (ii) 0-10 weight percent dye; (iii) 10-50 weight percent of a non VOC solvent; (iv) 5-60 weight percent of a thickener; (v) a sufficient amount of an alkalizer so that the hair coloring composition has a pH of 6-12.
Claims7
A hair dyeing composition consisting essentially of:
- (a) a developer phase consisting of:
- (i) water;
- and
- (ii) an oxidizing agent, wherein the developer phase has a viscosity of about 1 cps to about 5,000 cps;
- and
- (b) a tint phase consisting essentially of:
- (i) 0-40 weight percent water;
- (ii) 0.01-10 weight percent dye;
- (iii) 25-40 weight percent of a non volatile organic solvent that exhibits a vapor pressure of less than 0.1 mm Hg, wherein said non volatile organic solvent is selected from the group consisting of ethoxydiglycol, hexylene glycol, glycerin, and combinations thereof;
- (iv) from about 5 to about 20 weight percent based of the total weight of the tint phase of a fatty acid thickener, and from about 10 to about 30 weight percent based on the total weight of the tint phase of a thickener selected from the group consisting of fatty alcohols, emulsifying waxes, and combinations thereof, wherein the total amount thickener in the hair dyeing composition is from 10-50 weight percent;
- (v) 5-25 weight percent of an alkalizer;
- and
- (vi) optionally, an additive selected from the group consisting of quaternary ammonium salts, fragrances, chelating agents, antioxidants, solubilizing agents, and mixtures of the foregoing.
