Use of at least one aminophenol derivative of formula (I) below:in which: R represents a hydrogen atom or a radical &#x2014;COR, wherein Rrepresents a saturated or unsaturated, linear, cyclic or branched, optionally hydroxylated, Cto Chydrocarbon or alkoxy radical; Ris a radical of formula (a), (b) or (c) below: (a) &#x2014;CO&#x2014;NRR (b) &#x2014;CO&#x2014;O&#x2014;R (c) &#x2014;SO&#x2014;R wherein Rrepresents a hydrogen atom or a linear or branched, saturated or unsaturated, optionally hydroxylated, Cto Chydrocarbon radical, Rrepresents a hydrogen atom or a saturated or unsaturated, linear, cyclic or branched, optionally hydroxylated, Cto Chydrocarbon radical, and Rrepresents a saturated or unsaturated, linear, cyclic or branched, optionally hydroxylated, Cto Chydrocarbon radical, in a depigmenting and/or bleaching cosmetic composition for human skin, body hairs or head hair; compositions comprising the derivatives of formula (I) and a process for depigmenting and/or bleaching the skin, body hairs and/or head hairs.

Aminophenol derivatives and their use in cosmetics

Composition for topical application comprising at least one iminophenol compound

Retinyl carbonate derivatives, preparation process and uses

The invention relates to the use of aminophenol amide derivatives in a composition as an agent for depigmenting and/or bleaching human skin, body hairs and/or head hair. The invention also relates to a process for depigmenting and/or bleaching the skin, body hairs and/or head hair, which consists in applying a composition comprising aminophenol amide derivatives to human skin, body hairs and/or head hair.

Use of amino phenol amide derivatives as depigmentation agents

The present invention relates to novel retinol derivatives having the formula (I):

The invention relates to the use of oxamate derivatives in a composition, as agents for depigmenting and/or bleaching human skin, head hair and/or other hairs. The invention also relates to a process for depigmenting and/or bleaching the skin, head hair and/or other hairs, which includes applying a composition comprising oxamate derivatives to human skin, head hair and/or other hairs.

Use of oxamate derivatives as depigmenting agents

The use, in a topical cosmetic composition, or for the manufacture of a topical dermatological composition, intended for depigmenting and/or bleaching human skin, body hair or head hair, of at least one compound comprising a phenyloxime fragment.

Method of depigmenting and/or bleaching skin and/or body hair or head hair

The invention relates to the use of aminoalcohol derivatives containing a urea functional group corresponding to the following formula: ##STR1## in which: R.sub.1 represents a linear or branched, saturated or unsaturated alkyl radical having from 8 to 22 carbon atoms;

Cosmetic and dermatological compositions containing aminoalcohol

The present application relates to novel ceramide compounds to their process of preparation and to their use in cosmetics or in pharmaceuticals, in particular for treating and caring for the skin, hair, nails and eyelashes.

Ceramide compound, process of preparation and use

The invention relates to the use of aminoalcohol derivatives containing a urea functional group corresponding to the following formula: ##STR1## in which: R.sub.1 represents a linear or branched, saturated or unsaturated alkyl radical having from 8 to 22 carbon atoms; R.sub.2 represents a hydrogen atom or a linear or branched, saturated alkyl radical having from 1 to 6 carbon atoms; R.sub.3 represents a linear or branched, monohydroxylated or polyhydroxylated, saturated alkyl group having from 1 to 10 carbon atoms, in and for the preparation of cosmetic or dermatological compositions. These compounds are used in particular as moisturizing agents in care products for the skin or as conditioning agents in hair products.

Stable, topically applicable cosmetic/dermatological compositions well suited for artificially tanning or browning human skin and appropriately packaged, comprise at least one dihydroxyacetone (DHA) derivative convertible into DHA and, advantageously, at least one active species for effecting such conversion.

Active/stable artificial tanning compositions comprising DHA derivatives

A depigmenting cosmetic or dermatologic composition for use in bleaching the skin or treating pigmental spots contains in a vehicle suitable for topical application to the skin a benzofuran derivative having the formula ##STR1## wherein the OH function occupies position 5 or 6, R.sub.1 and R.sub.2, each independently, represent hydrogen or alkyl having 1-4 carbon atoms, n is 0 or 1, when n is 0, the C.sub.2 -C.sub.3 bond is a double bond, and when n is 1, the C.sub.2 -C.sub.3 bond is a single bond.

Depigmenting cosmetic or dermatologic composition containing a

The present invention relates to a novel process for the preparation of a monohydroxyindole or dihydroxyindole compound by a single step of placing in contact, in a solvent medium, at least one hydrolase with at least one indole compound bearing one or two radicals connected by an ester function to the benzene ring.
