A cosmetic or dermatological composition containing, as an active substance, at least one natural or recombinant spider silk protein, or an analog of such a protein. The composition may be in the form of hair products, skincare products, make-up products or antisun products.
Abstract:
The invention relates to novel histidine derivatives corresponding to the general formula (I) below: in which: R denotes a linear or branched, saturated or unsaturated alkyl radical containing from 6 to 22 carbon atoms, n is an integer ranging from 1 to 16, Q+ represents H+ or an organic or inorganic cation, and the addition salts with an acid. The invention also relates to a process for preparing the compounds of formula (I), as well as to the use of these compounds in cosmetics and pharmacy.
Abstract:
The invention concerns the use of flavylium type compounds, non-substituted in position 3, and substituted by at least a hydroxyl or alcoxy radical, in particular Apigenidin, in pure form or in the form of plant extracts containing them, as coloring agent in or for making compositions for dyeing keratinous fibers, particularly human keratinous fibers such as hair. The invention also concerns the dyeing compositions containing them, particularly cosmetic compositions for direct hair dyeing, and the corresponding dyeing method. The hair dyes resulting from the use of these coloring agents are particularly stable to light and washing.
Abstract:
Lysine derivatives, salts of the derivatives, their optical isomers of D or L configuration, or their mixtures, the derivatives containing an Ne-alkoxy or Ne-alkenoxycarbonyl group and having the formula: in which: R represents a linear or branched C13-C24 alkyl radical or alkenyl radicals, are used in cosmetic, pharmaceutical, hygiene or food compositions, particularly compact compositions.
Abstract:
Azo compounds of the 2-(4-amino)phenyldiazinecarboximidamide type and 2-(4-amino)phenylhydrazinecarboximidamide type, a process for their synthesis, their use for dyeing keratin fibers, dye compositions containing them, and dyeing processes.
Abstract:
The invention relates to a composition, in particular a cosmetic or dermatological composition, having an aqueous dispersion of vesicles with a lipid membrane, characterized in that the lipid membrane contains at least one carbamate of following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 are defined in the specification.
Abstract:
The subject of the invention is a process for the preparation of 2-aminoalkane-1,3,4-triols, in a single stage, preferably a single reduction state, from alkyl 2-hydroxyimino-3-oxo-4-acyloxyalkanoates. The invention makes possible a significant reduction in the number of stages and a marked improvement in the synthesis yields.
