The present disclosure relates to compositions for altering the tone or color of the hair, the compositions comprising at least one amino acid, at least one carboxylic acid, monoethanolamine, and at least one hair coloring agent comprising a direct dye. The disclosure also relates to methods of using the compositions.

The present invention relates to a process for coloring keratin fibers, preferably hair, comprising the steps of: (i) applying onto the keratin fibers a composition comprising (a) at least one compound chosen from alkylaminosulfonic acids and those of the formula (I) and (II), (b) at least one direct dye, and (c) at least one alkaline agent; (ii) heating the keratin fibers; and (iii) optionally rinsing and/or drying the keratin fibers. The present invention can provide superior coloring efficiency, such as color intensity and color lastingness.

The present invention is intended to provide an oily makeup cosmetic that is colorless in appearance but develops a color on application onto body surface, such as skin and lips. The present invention provides a colorless oily makeup cosmetic comprising (a) one or two dyes selected from Red No. 218 and Red No. 223, and (b) an oil agent, and a mixture of the component (a) and the component (b) at a mass ratio (a):(b) of 0.1:100 has a difference of 0.2 or less between the maximum absorbance and the minimum absorbance in a wavelength region of 500 to 600 nm. The oily makeup cosmetic may develop a color due to the component (a) on application onto body surface, such as skin and lips.

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dyes chosen from synthetic direct dyes and dyes of natural origin, b) one or more titanium salts and b1) optionally one or more particular carboxylic acids, c) one or more cellulose-based polysaccharides, d) optionally one or more organic compounds that are liquid at 25° C., with a Hansen solubility parameter value δH<16 (MPa).sup.1/2 at 25° C., e) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.

Described herein is a method for treating and coloring hair including un-pigmented hair. The method includes (a) providing a first composition including one or more heavy metal ion sequestrants; (b) applying the first composition to the hair; (c) providing a second composition including one or more weak acids having a pKa from 2.5 to 5; (d) applying the second composition to the hair; (e) providing a third composition including one or more direct dyes chosen from nitro dye, disperse dye, cationic dye, acid dye, basic dye, neutral azo dye and mixtures thereof, and (f) applying the third composition to the hair. The third composition is able to decrease the reflectance of un-pigmented hair in a wavelength range from 530 nm to 670 nm.

Disclosed are cosmetic formulation comprising (a) particulates having an absorption in the range of 400 to 800 nm; and (b) UV filters selected from (b.sub.1) particulate organic UV-filters; and (b.sub.2) soluble organic UV filters.

Provided are largely aqueous topical antimicrobial cleaning composition which provides an antimicrobial benefit, as well as methods for their production and methods for their use. The compositions comprise at least two different cationic surfactants which provide a primary antimicrobial benefit, and as a predominant further surfactant an amine oxide surfactant. The composition are at an acidic pH and are highly effective in providing an antimicrobial benefit to topical surfaces, e.g, epidermis and hair.

The present invention relates to a process for coloring keratin fibers, preferably hair, comprising the steps of: (i) applying onto the keratin fibers a composition comprising (a) at least one compound chosen from alkylaminosulfonic acids and those of the formula (I) and (II), (b) at least one direct dye, and (c) at least one alkaline agent; (ii) heating the keratin fibers; and (iii) optionally rinsing and/or drying the keratin fibers. The present invention can provide superior coloring efficiency, such as color intensity and color lastingness.

A hair coloring composition may include at least one selected from the group consisting of thioglycolic acid, cysteine, 3-mercapto-1,2 - propanediol, cysteamine, derivatives and salts thereof, and a basic dye, a HC dye, an amino acid, cationic surfactant, thickener, oil agent, pH adjuster, and wetting agent, wherein the pH of the hair coloring agent composition is 3.5 or higher.

The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol in combination with the oxidation base 2-(2,5-diaminophenyl)ethanol, wherein the pH of the agent is higher than 8.0.
