Abstract: The instant disclosure relates hair care compositions comprising ionic liquids or ionic mixtures. Ionic liquids or ionic mixtures are combined with a cosmetically acceptable carrier to form ready-to-use hair care compositions. The ionic liquids and the ionic mixtures are formed from; (1) thiolactic acid and/or one or more alkali metal or alkaline earth metal salts thereof; and (2) one or more amine compounds, and/or one or more ammonium cationic compounds, and/or one or more salts thereof. The ionic liquids, the ionic mixtures, and the hair care compositions comprising the ionic liquids or the ionic mixtures, are useful in methods for preventing hair damage, shaping hair, caring for hair, etc.

Abstract: The present invention relates to novel C-glycoside compounds of given absolute configuration, to a process for synthesizing them and to compositions containing them. The invention also relates to the cosmetic use of these C-glycoside compounds as agents to stimulate the synthesis of glycosaminoglycans containing a D-glucosamine and/or N-acetyl-D-glucosamine residue, advantageously hyaluronic acid, and/or of proteoglycans, advantageously proteoglycans containing hyaluronic acid, by fibroblasts and/or keratinocytes. The invention also relates to a cosmetic process for treating keratin materials using a composition containing at least one C-glycoside compound according to the invention.

Abstract: The present invention relates to novel compounds of formula (I) where: X is an —OH or ?O grouping; n is an integer between 0 and 5; R? is H or a C1-C4 alkyl radical, when n?2, two adjacent —OR? groupings can together form the divalent radical —O—CH2—O—; except when X?OH, the compound does not comprise a double ethylene link in the alpha position of the carbon having said OH. The invention also relates to the salts thereof, to the optical isomers thereof, to the cosmetic and pharmaceutical compositions containing same, and to the use thereof to prevent and cosmetically treat the signs of aging on the skin.

Abstract: A subject-matter of the invention is a composition comprising a) at least one ortho-diphenol derivative, b) at least one specific metal derivative and c) at least one basifying agent, a method for dyeing keratinous fibers by treatment of the said fibers using the ingredients a), b) et c) and the use thereof for dyeing keratinous fibers. This hair dyeing method makes it possible to obtain better colorations which are more uniform, chromatic and lasting and which do not detrimentally affect the cosmetic properties of the keratinous fibers, starting from an extract of ortho-diphenols which are in particular natural.
