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 disclosure relates to color-altering compositions. The compositions comprise a hair color-altering agent and at least one carboxylic acid. Certain compositions further comprise at least one amino acid or amino sulfonic acid, and/or a salt thereof selected from the group consisting of taurine, aspartic acid, cysteine, lysine, methionine, tyrosine, phenylalanine, carnitine, a salt thereof, and a mixture thereof. Also provided are kits and methods of using said color-altering compositions.

A composition comprising direct, indirect and related pathway endocannabinoid mimetic compounds and methods of using the composition.

A method of treating hair to reduce frizz involving the following steps: (i) prewashing the hair with water, (ii) applying a frizz reducing product to the hair using at least one of a brush and a spray, (iii) drying the hair in air, (iv) rinsing the hair with water, (v) drying the hair, (vi) applying to the hair a flat iron, and (vii) rinsing the hair with water. The frizz reducing agent used to treat hair is glyoxylic acid. The specific temperature the flat iron is set will depend on the specific hair type and degree of frizz.

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.

Personal care topical compositions at skin-tolerant pH with cystine which is solubilized or has small crystal size below 20 microns. A process of making the composition is also described.

A method of lyophilizing exosomes using a cryoprotectant comprising methionine, mannitol and trehalose is disclosed. The lyophilized exosome product shows a good appearance which maintains a porous sponge shape without forming ice crystals. In addition, the lyophilized exosome product can be applied to a pharmaceutical composition, a skin external preparation and a cosmetic composition. For example, the lyophilized exosome product can be used as a solution obtained by simply mixing it with a diluent.

Multiple emulsions comprising an internal phase which is an oil continuous nanoemulsion are described. The multiple emulsions are water continuous, stable, provide moisturizing benefits and can comprise a high concentration of water soluble actives.

Personal cleansing compositions are disclosed with a synergistic combination of anionic surfactants in that impart early formation of foam with lasting foam stability. An anionic sulfate surfactant is provided in combination with a bio renewable alkyl sulfoacetate/alkyl ethoxy sulfoacetate surfactant for use as a liquid hand soap, liquid body wash, antimicrobial or sanitizing composition, or shampoo. The surfactant combination is also less irritating to skin. Methods of use and methods of making such compositions are also disclosed.

A hair care booster in powder form comprises an organic carboxylic acid, a proteinogenic amino acid, a purine or purine degradation products, amino acid degradation products and an alkalizing agent. A cosmetic product comprises the hair care booster in powder form and a separately prepared hair care product. A method comprises mixing the hair care booster in powder form with a hair care product and obtaining a ready-to-use mixture.
