A method of treating a material, the method comprising contacting the material with a composition comprising a hydroxy-substituted aldehyde. In preferred aspects of the invention the material is a keratinous material.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.

A cosmetic agent for treating keratin fibers is provided herein. The cosmetic agent includes, in a cosmetically acceptable carrier, in relation to the total weight of the cosmetic agent, from about 0.001 to about 10 wt. % of at least one protein which has a content of glutamic acid and/or aspartic acid of from about 10 to about 60%, in relation to the total content of all amino acids of the protein. The cosmetic agent further includes, in a cosmetically acceptable carrier, in relation to the total weight of the cosmetic agent, from about 0.01 to about 10 wt. % of at least one salt which includes at least one divalent cation, and/or of at least one salt which includes at least one trivalent cation.

A hair treatment agent for reducing and/or preventing the bleeding out and/or fading of artificially produced hair colors is provided herein. The hair treatment agent has a pH value in the range of from about 4 to about 5. The hair treatment agent includes, relative to the total amount of the hair treatment agent, from about 0.01 to about 10% by weight of a lanthanum and/or lanthanide salt, at least one anionic surfactant selected from the group of alkyl (ether) sulfates, sulfosuccinates, ether carboxylic acids, N-acylamino acids having 8 to 24 C atoms in the acyl group, (acyl) isethionates having 8 to 24 C atoms in the acyl group, and mixtures of these surfactants, and from about 0.01 to about 10% by weight of an organic acid selected from the group of maleic acid, lactic acid, acetic acid, propanoic acid, amino acids, and mixtures thereof.

Suggested is a hair care blend, comprising: (a) at least one wheat bran extract, and (b1) at least carboxylic acid alkyl ester and/or (b2) at least one diol.

The present invention relates to a composition (F) for treating keratin fibers, notably human keratin fibers such as the hair, comprising at least one alkoxysilane of formula (I), at least one alkoxysilane of formula (II), at least one nonamino silicone of formula (III), optionally at least one coloring agent chosen from pigments, direct dyes and mixtures thereof, and optionally water.

A method of combatting colour loss from a dyed material, the method comprising contacting the material with a composition comprising an amine salt of a carboxylic acid wherein the carboxylic acid has 4 to 10 carbon atoms.

A method of combating colour loss from a dyed material, the method comprising contacting the material with a composition comprising a hydroxy-substituted aldehyde.

Compositions are described that include an oil, a surfactant, and optionally a charged polymer complex, where the composition may also include an aqueous phase to provide a microemulsion. Methods of manufacturing the compositions are also described, along with methods of using the compositions in home care and personal care.

The present disclosure relates to methods for inhibiting color fading in hair and for improving the color durability and stability of artificial color of hair. The methods entail forming a layer-by-layer (LbL) film on hair, and optionally forming a cationic surface layer on the LbL film. The LbL film is formed by applying a cationic silane layer on the hair and subsequently applying an anionic polymer layer on the cationic silane. Multiple cationic silane layers and anionic polymer layers can sequentially be added as desired. Finally, the LbL film may comprise a cationic surface layer.
