The invention relates to a cosmetic composition, especially a hair composition, and to a method for the cosmetic treatment of keratin materials, especially of the hair, employing compounds of formula: in which Z represents (i) a hydrogen atom, (ii) a linear or branched C1 to C32 (saturated) alkyl radical; (iii) a linear or branched C2 to C32 (unsaturated) alkene radical, comprising one or two C═C double bonds; (iv) an aryl-substituted alkyl radical; said radicals being optionally substituted and/or interrupted.
摘要:
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.
摘要:
The present invention relates to a cosmetic process for treating keratin materials, which can give them, especially in a long-lasting and reversible manner, interesting cosmetic properties; this process comprising the application to said materials: in a first stage, of a cosmetic composition comprising at least one graftable species, comprising at least one unit of formula (Ia): and in a second stage, of a cosmetic composition comprising at least one cosmetic active agent bearing at least one unit of formula (Ia): The invention also relates to a kit comprising said compositions.
摘要:
The invention relates to a composition for dyeing keratin materials, and in particular human keratin fibres such as the hair, comprising at least one 2-pyrrolidone functionalized in the 4 position with an ester or amide radical, and at least one hydrophobic direct dye or a pigment; a dyeing process using this composition. Similarly, the invention relates to the use of the said pyrrolidone combined with a direct dye or a pigment for dyeing keratin materials, and especially to the use of the said pyrrolidone for improving the colour uptake onto the fibres of direct dyes that are sparingly soluble or insoluble in aqueous-alcoholic supports. The invention also relates to novel pyrrolidone derivatives. The present invention makes it possible in particular to obtain direct dyeing on keratin materials that is fast, resistant to washing, chromatic and powerful.
