摘要:
Transparent cosmetic composition that reflects infrared radiation and its use for protecting the human epidermis against infrared radiation.The invention relates to a transparent cosmetic composition comprising, by way of an agent that reflects infrared radiation for protecting the human epidermis, a substance which is dispersible in the cosmetic medium used, possessing a reflectance (R) of infrared radiation equal to at least 45%, and of which a 2% strength dispersion in vaseline possesses an optical transmission in the visible of at least 85%, chosen from a diatom of particle size less than 100 microns, hollow glass microspheres of size less than 100 microns, a bismuth oxychloride of particle size less than 75 microns and zirconium powder covered ceramic microparticles of particle size less than 8 microns.This cosmetic composition can also contain 0.5 to 20% by weight of UV-A, UV-B or broad-band screening agents.
摘要:
The invention relates to a dyeing composition for keratinous fibres containing, in a suitable vehicle, at least one nitrated direct dye of the 2-nitro-paraphenylenediamine series, in which the amino group in position 4 is mono- or disubstituted with lower alkyl or hydroxyalkyl radicals and in which the amino group in position 1 is optionally monosubstituted with a lower alkyl or hydroxyalkyl radial, and the aromatic ring can be substituted or unsubstituted on the remaining positions; the invention consists in introducing into such a composition an imidazolidinedione or one of its substitution derivatives, to improve the solubility of the abovementioned nitrated direct dye by a co-solubilization phenomenon. The invention also relates to a process for dyeing keratinous fibres using such compositions.

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 transparent cosmetic composition that protects the human epidermis, containing, in a cosmetically acceptable vehicle, by way of an agent that reflects infrared radiation, 0.5 to 10% by weight of titanium dioxide flakes of dimensions between 1.5 and 25 microns, dispersible in the cosmetic medium used, possessing a reflectance (R) of infrared radiation equal to at least 45%, and of which a 2% strength dispersion in vaseline possesses an optical transmission in the visible of at least 85%.This cosmetic composition can also contain 0.5 to 20% by weight of UV-A, UV-B or broad-band screening agents.
