The present invention is directed at organic ammonium salts comprising

an organic ammonium-group-comprising cation which does not contain an estolide moiety and a carboxylate anion (COO—) group-comprising anion selected from the group consisting of anions containing at least one estolide moiety or carboxylate anions containing at least one internal ester group.

The invention is also directed at a process for the production of such organic ammonium salts, the use of such organic ammonium salts in cosmetic formulations for skin and hair care, the use of such organic ammonium salts for the treatment of fibers, the use of the organic ammonium salts for the treatment of hair, at compositions containing such organic ammonium salts, the use of the products of the process for the production of organic ammonium salts in cosmetic formulations for skin care and hair conditioner and hair shampoo, the use of said products for the treatment of fibers, and compositions containing said products for the treatment of hair.

The present invention relates to a kit comprising: at least one microneedle sheet (1) comprising a substrate layer and a plurality of microneedles on the substrate layer, the microneedles comprising at least one water-soluble or water-dispersible polymer; and a device comprising an applicator (2-3) comprising an application surface, a container (2-1) comprising a cosmetic composition and a valve, wherein the microneedle sheet (1) is capable being attached to the applicator (2-3) by attaching the substrate layer of the microneedle sheet to the application surface, the applicator (2-3), the container (2-1) and the valve are configured to supply the cosmetic composition via the valve onto the microneedle sheet (1). The kit according to the present invention can prevent the repeated use of microneedles (1), and can apply a cosmetic product in an easy and sanitary manner.

A method for strengthening and repairing keratin fibres including providing a first—and a second crosslinking composition, wherein the first—crosslinking composition comprises an at least bi-functional Brønsted-base and the second—crosslinking composition comprises—an at least bi-functional organic acid, and a cosmetically acceptable carrier; applying the first—as well as the second—crosslinking composition to keratin fibres; and optionally mixing the first—crosslinking composition into a commercially available hair coloring or hair bleaching composition.

The invention relates to a non-therapeutic cosmetic use of fructans of Agave tequilana, containing natural inulins for protecting capillary fibre by improving the hydrophobicity of the capillary fibre. The invention also relates to a non-therapeutic cosmetic method comprising the therapeutic application of fructans of Agave tequilana containing inulins having a degree of polymerisation greater than 10, in order to protect the capillary fibre by improving the hydrophobicity of the capillary fibre, said application being optionally followed by rinsing.

This disclosure relates to a composition for coloring hair containing comprising a multi-lamellar gel emulsion, which includes a haircolor formulation, and a method of making the same. The multi-lamellar gel emulsion includes about 0.5 wt % to about 4.0 wt % of cosmetically acceptable emulsifying fats, a cosmetically acceptable non-ionic surfactant, a water-soluble suspending polymer, and at least 80 wt % of water.

The present invention relates to a hair cosmetic containing the following components (A) to (C): (A) a compound represented by the following general formula (1) or a salt thereof: ##STR00001## wherein a broken line represents the presence or absence of a π bond; R.sup.1 represents a hydroxy group or an acetoxy group; R.sup.2 represents a hydrogen atom or —COOR (R is a hydrogen atom, a methyl group, or an ethyl group); and R.sup.3 represents a hydrogen atom, an acetyl group, a methyl group, or an ethyl group; (B) a dimethylsilicone; and (C) an amino-modified silicone, the hair cosmetic satisfying such conditions that a mass ratio of the component (C) to the component (B) [(C)/(B)] is 0.3 or more and 3.0 or less; and a mass ratio of the component (A) to the component (B) and component (C) {(A)/[(B)+(C)]} is 1.0 or less.

Shake Well. Apply a few drops once a week or as needed on damp or dry hair, massage well, and style as usual.

Precaution: if this product causes any irritation, please stop using it. If the product becomes clumpy or appears solid just emerged in hot water before use.

Disclosed is a composition comprising at least one core-shell microcapsule in a suspending medium. The microcapsule comprises a core and a shell around said core. The shell comprises a hyperbranched polysaccharide selected from the group consisting of amylopectins, dextrins, hyperbranched starches, glycogen and phytoglycogen and mixtures thereof.

A method of protecting the internal protein of hair from damage by ultraviolet light, comprising the step of applying, to the hair, a hair treatment composition comprising a lactone, a disaccharide, an inorganic salt and an organic acid or salt thereof, having a pH in the range of from 3 to 6.5 prior to the application of an ultraviolet light to the hair, and a use of such a hair treatment composition, in the treatment of hair, to protect hair from damage by ultraviolet light.
