摘要:
The use in and for the preparation of both cosmetic and/or dermatological compositions comprising at least one amphoteric copolymer that is crosslinked and/or branched and derived, e.g., from a mixture comprising at least one monomer selected from acrylate, methacrylate, acrylamide, and methacrylamide monomers comprising at least one C8-C30 fatty chain. Another subject of the invention is the application of the composition for the treatment of keratinous materials and in particular of the skin, hair, eyelashes, and nails.
摘要:
The invention provides compositions intended for the treatment of fibrous materials. These compositions contain at least one cationic polymer, at least one anionic polymer, at least one alkali metal salt and at least one non-ionic surface-active agent or surface-active agent which contains one or more carboxyl or carboxylate groups in addition to non-ionic groups.
摘要:
Composition for washing keratinous materials, especially the hair and the skin, characterised in that it comprises, in an aqueous medium, at least one silicone, at least one surfactant possessing detergent properties and at least one alcohol having 27 to 44 carbon atoms and containing one or two ether and/or thioether or sulphoxide group(s), corresponding to the formula (I): ##STR1## in which R.sub.1 and R.sub.2, which may be identical or different, denote linear C.sub.12 to C.sub.20 alkyl groups;X denotes an oxygen atom, a sulphur atom or a sulphoxide group;Y denotes an oxygen atom, a sulphur atom, a sulphoxide group or a methylene group;in the case where Y denotes a methylene group, the sum of the numbers of carbon atoms in R.sub.1 and R.sub.2 varies from 24 to 40, and preferably from 26 to 36, inclusive, and when Y does not denote a methylene group, the sum of carbon atoms in R.sub.1 and R.sub.2 varies from 24 to 40 inclusive, and preferably from 28 to 36 inclusive; when X or Y denotes sulphoxide, Y or X does not denote sulphur.
摘要:
Cosmetic compositions for bleaching hair comprising at least one oxidizing agent selected from peroxygen compounds and at least one block and/or random linear polyoxyethylene/polyoxypropylene copolymer, the copolymer being anhydrous and, at room temperature, further being both liquid and soluble in water, and the composition being pulverulent and anhydrous. Bleaching powders that are fine, anhydrous, free-flowing, homogeneous, non-dusty, are perfectly dispersible in hydrogen peroxide and have improved cosmetic properties.
摘要:
A urethane derivative from amino acids has the formula ##STR1## wherein R represents --CH.sub.2 OH, --CHOH--CH.sub.3 or --(CH.sub.2).sub.3 --NH--CO--NHY, Y represents --H or --COOR', R' represents linear or branched alkyl, optionally unsaturated, having 8-24 carbon atoms, or a monocyclic cycloalkyl substituted by an alkyl whose total number of carbon atoms is equal to or greater than 10, or to the salts of the derivative of formula I or to a mixture of the derivatives of formula I and/or their salts. A method is given for the preparation of the urethane derivative of formula I, as are examples of cosmetic or pharmaceutical compositions containing the urethane derivative, as a hydrating agent, for the treatment of dry skin.
摘要:
The invention relates to a lipid compound of formula (I): ##STR1## where R.sub.1 denotes a C.sub.11 to C.sub.21 alkyl or alkenyl radical and R.sub.2 denotes a linear or branched C.sub.8 to C.sub.30 hydrocarbon radical, saturated or bearing one or more ethylenically unsaturated bonds, and also to a process for preparing it and to compositions for cosmetic use of pharmaceutical use for skin conditions containing this compound.
摘要:
The invention provides surface-active random oligomers of the general formula:R.sub.1 --O--C.sub.2 H.sub.3 (Z)--O].sub.n H (I)in which R.sub.1 denotes a linear or branched, saturated or unsaturated aliphatic hydrocarbon radical or a cyclo-aliphatic, aromatic or alkylaromatic radical containing 1 to 30 carbon atoms, Z denotes a group A and/or at least one group corresponding to the formula (II)R.sub.2 --O--C.sub.2 H.sub.3 (A)--O].sub.m CH.sub.2 -- (II)in which R.sub.2 denotes a hydrocarbon radical having the meaning indicated for R.sub.1 and containing a number of carbon atoms from 8 to 30, n denotes an average statistical value from 1 to 20, m denotes an average statistical value from 0.5 to 10 and A denotes a group of hydrophilic character. These oligomers can be used in cosmetic or pharmaceutical compositions.
