Abstract: The invention relates to compositions comprising pholyphenol derivatives, characterised in that said polyphenols contain monomers, oligomers or polymers with units having formula (I), said units being characterised by the simultaneous presence of a resorcinol nucleus (nucleus A) and a para-phenol nucleus (nucleus B) which are interconnected by a carbon bond C, said derivatives being over-activated, in respect of the nucleophilic power thereof, by alkylation of at least one phenol function of each constituent monomer unit and stabilised by sterification by mixtures of fatty acids in proportions reflecting those of vegetable oils formed mainly by unsaturated fatty acids of all of the other phenol functions. The invention is suitable for use in cosmetics, dietetics and therapeutics.

Abstract: The invention relates to compositions of polyphenol derivatives, characterised in that said polyphenols contain monomers, oligomers or polymers of units of the formula (I), wherein said units are characterised by the simultaneous presence of a phloroglucinol-type core (core A) and of a catechol-type core (core B) bonded together by a segment of 3 carbons such as C, said derivatives being over-activated in terms of nucleophilic power by the alkylation of at least one phenol function of each constituent monomer unit, and stabilised by the esterification of all the others with mixtures of fatty acids in proportions representing those of vegetable oils mainly consisting of AGI.
