Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compound having formula (I): said compound being selecting from the group consisting of: the optical isomers thereof, diastereoisomers thereof and corresponding salts thereof. 2. The compound of formula (I) as claimed in claim 1 , selecting from the group consisting of: 3. A composition comprising at least one compound as claimed in claim 1 . 4. The composition as claimed in claim 3 , wherein the compound is present in an amount of from 0.01% to 20%, relative to the total weight of the composition. 5. Method for promoting skin desquamation, stimulating epidermal renewal, combating the signs of skin aging, improving the radiance of the complexion and/or smoothing out facial skin, comprising a step of applying to the skin at least one compound of formula (I): said compound being selecting from the group consisting of: or the optical isomers thereof, diastereoisomers thereof and corresponding salts thereof. 6. The method as claimed in claim 5 , wherein the compound of formula (I) is selecting from the group consisting of: 7. The composition as claimed in claim 3 , wherein the compound is present in an amount of from 1% to 5% by weight, relative to the total weight of the composition.
