Definitions
- the present invention relates to a new cosmetic or dermatological composition
- a new cosmetic or dermatological composition comprising in combination mequinol (or 4-hydroxyanisole) and an alpha-hydroxylated acid (or alpha hydroxy-acid or AHA), usable by topical application for depigmentation of the skin.
- the composition according to the invention may also contain a sunscreen.
- the pigmentation of the skin results from the synthesis of melanin in the melanocytes of the dermis by the transformation of tyrosine under the influence of a cuproprotein enzyme tyrosinase.
- Mequinol or 4-hydroxyanisole has long been known as a compound having depigmenting activity (Brun R, Journal of the society of cosmetic chemists (1960), 11, 571-9).
- mequinol as a depigmenting agent is to act as a substrate for tyrosinase (Riley P, Journal of Pathology (1969), 97 (2) 1 185-91 and Journal of Pathology (1969), 97 ( 2), 193-206.
- Citric acid or malic acid are known in the prior art in cosmetic and pharmaceutical compositions as chelating or oxidizing agents at low concentrations, less than 0.01% relative to the total weight of the composition.
- the invention therefore relates to a depigmenting composition for the skin comprising, in a physiologically acceptable medium, mequinol and at least one alpha hydroxylated acid.
- physiologically acceptable medium means a medium compatible with the skin, the mucous membranes and / or the integuments.
- the hydroxy acids to which the invention applies can be linear, branched or cyclic, saturated or unsaturated.
- the hydrogen atoms of the carbon chain can, in addition, be substituted by halogens, halogenated, alkylated, acylated, acyloxylated, alkoxycarbonylated or alkoxylated radicals having from 2 to 28 carbon atoms.
- the ⁇ -hydroxy acid which can be used according to the invention may consist of a mono- or polycarboxylic acid comprising one or more hydroxy functions, at least one of these hydroxy functions having to occupy an ⁇ position on said acid.
- the ⁇ -hydroxy acids of the invention are ⁇ -hydroxy-alkanoic having from 2 to 18 carbon atoms.
- ⁇ -hydroxy acids that can be used in the invention, there may be mentioned in particular glycolic (or ⁇ -hydroxyethanoic), lactic (or ⁇ -hydroxypropanoic), malic (or hydroxybutanedioic), tartaric (or dihydroxybutanedioic), citric, mandelic acids, ⁇ - hydroxycaprylic (or ⁇ -hydroxyoctanoic), ⁇ -hydroxy-hexanoic, ⁇ - hydroxydecanoic, ⁇ -hydroxydodecanoic, ⁇ -hydroxy-tetradecanoic, ⁇ - hydroxyhexadecanoic, ⁇ -hydroxyoctadecanoic, ⁇ -hydroxyeisanoic, ⁇ - hydroxydocosanoic, ⁇ -hydroxyhexosanoic ⁇ -hydroxyoctacosano ⁇ que.
- glycolic or ⁇ -hydroxyethanoic
- lactic or ⁇ -hydroxypropanoic
- malic or hydroxy
