Use of hydroxyanthraquinones for the coloration of human keratin fibres, and process and composition in which they are used.The composition contains, in a cosmetically acceptable medium, at least one hydroxyanthraquinone of the formula: ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 independently of one another denote a hydrogen atom, a hydroxyl group, an alkyl group, an alkyl group substituted, for example, by a hydroxyl, amino or acyl group, an alkoxy group, a nitro group, a halogen group, a group SO.sub.3 H, CHO, CO.sub.2 H or SO.sub.3 Na, or a group --CO.sub.2 R', in which R' denotes alkyl or an alkali metal, with the proviso that: at least two of the groups R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 denote hydroxyl, and that if R.sub.1 and R.sub.2 denote OH, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 denoting hydrogen, then at least one of the two groups R.sub.3 and R.sub.4 is different from hydrogen, or alternatively if R.sub.1 and R.sub.3 denote OH, R.sub.2 and R.sub.4 denoting hydrogen and one or two of the substituents R.sub.5, R.sub.6, R.sub.7 and R.sub.8 denoting hydroxyl, then at least one of the substituents R.sub.5, R.sub.6, R.sub.7 and R.sub.8 is different from hydrogen, alkyl or halogen.
摘要:
The invention discloses the use of hydroxyl derivatives of benzaldehyde for coloring keratin fibres without an oxidizing agent. These derivatives are of the type which correspond to the formula: ##STR1## in which R denotes a linear or branched lower alkyl group which is optionally substituted by one or two OH groups, n is equal to 1, 2 or 3, m is equal to 0, 1 or 2 and the sum n+m is equal to 2 or 3.
摘要:
The invention relates to a composition for dyeing keratinic fibres, especially human hair, which contains 5-nitrovanillin of formula: ##STR1## in an aqueous, alcoholic or hydroalcoholic carrier. This yellow nitro dye makes it possible to obtain stable shades having good light- and shampoo-resistance when it is used by itself or in combination with blue or violet nitrobenzene dyes, and optionally with other direct dyes.

The present invention relates to a sunscreen composition containing at least one oil-soluble agent absorbing UV rays as well as at least one polyisobutylene which is liquid at ambient temperature, with a viscosity-average molecular weight of between 8,000 and 65,000, in a cosmetically acceptable medium incorporating at least one fatty phase.Such a suncreen composition, applied on the skin, has an improved protection index.
摘要:
A process for dyeing keratinous fibers employs a dye composition containing an oxidation base selected from a paraphenylenediamine, an N,N'-diphenylalkylene diamine, a para-aminophenol, an ortho-aminophenol, an ortho-phenylenediamine or a heterocyclic oxidation base, in combination with iodide ions. The application of this dyeing composition to the keratinous fibers is preceded or followed by the application to the fibers of a composition containing hydrogen peroxide.
