The present invention is directed towards the cosmetic use of at least one compound of formula (I) and/or solvates thereof and/or stereoisomers thereof:   or of a composition comprising, in a physiologically acceptable medium, at least one compound of formula (I),for treating and/or preventing the signs of ageing and/or of photoageing of keratin materials, preferably of the skin.

Polyhydroxylated (1-phenyl-2-phenyl) ethylene derivatives as an anti-ageing and photoprotective agent

A subject matter of the present invention is the cosmetic use of at least one compound of formula (I): in which: (II) denotes a divalent radical chosen from a carbon-carbon single bond *&#x2014;CH&#x2014;CH&#x2014;* or double bond *&#x2014;CH&#x2550;CH&#x2014;*, of Z or E configuration or their mixtures, b=0 or 1, c=0 or 1, d=0, 1 or 2, and R and R' independently denote a hydrogen atom, a linear C-Calkyl radical or a branched C-Calkyl radical, to treat and/or prevent signs of aging and/or of photoaging of keratinous substances, preferably of the skin, and/or to depigment, lighten and/or whiten keratinous substances, preferably the skin. The present invention also relates to novel compounds and to a corresponding cosmetic method. 

Carboxylated polyphenol derivatives and their cosmetic use

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.

Hair care compositions comprising thiolactic acid-based ionic liquids or thiolactic acid-based ionic mixtures

A subject matter of the present invention is the cosmetic use of at least one compound of formula (I): in which: denotes a divalent radical chosen from a carbon-carbon single bond *&#x2014;CH&#x2014;CH&#x2014;* or double bond *&#x2014;CH&#x2014;CH&#x2014;*, of Z or E configuration or their mixtures, b=0 or 1, c=0 or 1, d=0, 1 or 2, and R and R' independently denote a hydrogen atom, a linear C-Calkyl radical or a branched C-Calkyl radical, to treat and/or prevent signs of aging and/or of photoaging of keratinous substances, preferably of the skin, and/or to depigment, lighten and/or whiten keratinous substances, preferably the skin. The present invention also relates to novel compounds and to a corresponding cosmetic method.

The present invention relates to compounds of formula (I): in which R1 is a hydrogen atom, a phenyl radical, or a straight or branched, saturated or unsaturated hydrocarbon radical having 1 to 8 carbon atoms.

Method for synthesizing novel compounds derived from 3-hydroxy-cylopentyl acetic acid

Method for synthesizing novel compounds derived from 3-hydroxy-cyclopentyl acetic acid

The present invention relates to the cosmetic use, in a composition containing a physiologically acceptable medium, of at least one compound of formula (I) in which: &#x2014;Rmeans a hydrogen atom or a hydroxyl radical, &#x2014;Rand Rmean, independently of each other, a hydrogen atom, a linear or branched C1-C6 alkyl radical; a benzyl radical; a linear or branched C1-C6 alkylcarbonyl radical not conjugated with the carbonyl; or a linear or branched C1-C6 alkoxycarbonyl radical, and/or of an isomer and/or of a salt and/or of a solvate of said compound of formula (1), for preventing and/or treating the signs of ageing of the skin and its appendages. 

Composition comprising at least one 2-(3,4-disubstituted)phenyl-1-(3,4-disubstituted)phenyl-1-hydroxyethane for preventing and/or treating the signs of ageing of the skin

The present invention relates to novel compounds of formula (I) to compositions comprising same, and also to the use thereof for preventing and/or cosmetically treating the signs of aging of the skin.

1-phenylmono- or -polyhydroxypropane compounds, compositions and cosmetic uses thereof

The present invention relates to novel compounds of formula (I) to cosmetic compositions comprising same, and also to the use thereof for preventing and/or cosmetically treating the signs of aging of the skin.

1,2-diphenylethylene glycol compounds for combating aging of the skin, and cosmetic use thereof

The invention relates to the cosmetic use of at least one compounds according to the following formula (I), as an anti-dandruff agent or for preventing and/or treating scalp dandruff: where 'sugar' denotes a monosaccharide residue chosen from rhamnose, xylose, fucose, mannose, lyxose, and arabinose; where R, substituting the anomeric oxygen in the sugar (represented by 'O' in formula (I)), denotes a radical comprising 6 to 38 carbon atoms chosen from: &#x2014;a linear or branched, saturated alkyl radical; &#x2014;a linear or branched, alkenyl radical; said linear or branched saturated alkyl radical being optionally substituted by at least one OH and/or NH2 function; &#x2014;if &#x201c;sugar&#x201d; denotes a mannose residue, R denotes a linear C6-C38 alkyl radical, substituted by at least one OH function or an NH2 function; and the salts and solvates and/or optical isomers thereof, alone or in a mixture, particularly racemic forms. The invention also relates to compounds according to formula (I), and cosmetic compositions containing same. 

Anti-dandruff sugars

The invention relates to the use, as an agent for treating human perspiration, in a cosmetic composition, of amino acid derivatives of formula (I) below:  The invention also relates to a cosmetic process for treating perspiration and possibly the body odour associated with human perspiration, especially underarm odour. The invention also relates to novel amino acid derivatives of formula (II) that will be defined in detail hereinbelow, and to cosmetic or dermatological compositions containing them.
