摘要:
The present invention relates to a cosmetic and/or dermatological composition comprising in a physiologically acceptable medium at least one merocyanine derivative of formula (1) or (2) and/or its E,E-, E,Z- or Z,Z-geometrical isomer forms: comprising specific polar groups consisting of hydroxyl- and ether-functionalities. Another object of the present invention relates to a cosmetic process for controlling and/or improving the darkening of the skin under exposure to UV radiation and the homogeneity of the colour of the complexion which comprises the application onto the skin of a cosmetic composition as above defined. Another object of the present invention relates to a cosmetic process for protecting the keratinic materials and particularly the skin against photo-ageing which comprises the application onto the keratinic material of a cosmetic composition as above defined.

摘要:
Disclosed are compounds of formula (1) and (2) and/or E/E-, E/Z- or Z/Z geometrical isomer forms thereof; wherein R1-R5, R1-R11 and A are defined as in description. The compounds are used as UV absorbers for protecting household products from photolytic and oxidative degradation, as plastic additives, preferably for food and pharmaceutical packaging applications, for preventing photo-degradation of food by incorporation of the compounds of formula (1′) and/or (2′) into transparent food containers, for protection of UV-A sensitive drugs from photo-degradation by incorporation of UV absorber in transparent blister foils or transparent pharmacy containers, as additives for photographic and printing applications, as additives for electronic applications and protecting the ingredients in agriculture applications.

The invention relates to compounds of formula (I): The invention likewise relates to a cosmetic method for depigmenting, lightening and/or whitening keratin materials, more particularly the skin, that utilizes these compounds
摘要:
The invention relates to the cosmetic use, as a skin moisturizer, of a compound of formula (I): with (i) R1 and R2 represent a hydrogen atom or a C1-C6-alkyl group, or (ii) R1 and R2 can form, together with the nitrogen atom which bears them, a saturated heterocycle with 5 to 7 ring members; R5 representing a hydrogen atom or a (C1-C3) alkyl group; R6 representing a hydrogen atom or a (C1-C4) alkyl group; R3 represents a hydrogen atom or a (C1-C6) alkyl-group, or —OR3 represents a phosphate group; it being possible for the two groups R3 to form, together, an isopropylidene group; R4 represents a hydrogen atom or —OR4 represents a-phosphate group; and the salts, solvates and isomers thereof. The invention also relates to a cosmetic composition comprising a compound (I) and the corresponding new compounds.
摘要:
A cosmetic regime or regimen for depigmenting, lightening and/or bleaching keratin materials, especially the skin, entails topically applying thereon a cosmetic composition containing a dithiolane compound of formula (I): in which: Y is O, NR1 or S R1 is a hydrogen atom; a C1-C20 alkyl radical or an optionally substituted phenyl radical; R is a hydrogen atom; or a C1-C20 alkyl radical, or an optionally substituted phenyl radical, or a C1-C8 alkyl radical containing an optionally substituted phenyl substituent; n=0 or 1 or 2; and also the salts, chelates, solvates and optical isomers thereof.
