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.

Nos. 2,199,971, 2,236,515 and 2,282,426, and more particularly, 4-(2-oxo-3-bornylidenemethyl)phenyltrimethylammonium methylsulphate and 4-(2-oxo-3-bornylidenemethyl)benzenesulphonic acid and its metal or ammonium salts.Application as a sunscreen composition for the skin, a protective composition for the hair or as a light-stabilized cosmetic composition.
摘要:
A cosmetic composition for the treatment of the hair and skin comprising, in an aqueous medium, particles of pulverized flowers or flower tops having a granulometry lower than 125 microns and a cohesion agent present in an amount effective to maintain the homogeneity of the composition. The cohesion agent can be a thickening agent, a water-in-oil emulsion or an oil-in-water emulsion.
