摘要:
The use in dyeing human keratin fibres, especially human hair, of 2-hydroxy-1,4-naphthoquinones of the formula: ##STR1## in which R.sub.1 denotes a hydrogen or halogen atom, or a hydroxy, alkoxy, nitro, alkyl or acyl group, and R.sub.2, R.sub.3, R.sub.4 and R.sub.5 independently of one another denote hydrogen or a hydroxyl, alkoxy, alkyl or acyl group, such that at least one of the substituents R.sub.1 to R.sub.5 is other than hydrogen, and if R.sub.1, R.sub.3 and R.sub.4 denote hydrogen, R.sub.2 and R.sub.5 cannot simultaneously denote hydroxyl is described.

The invention relates to the use, for dyeing keratin fibres, and in particular human hair, of benzoquinone derivatives of the formula: ##STR1## in which R.sub.1 and R.sub.3 independently of one another denote hydrogen, a hydroxyl group, an alkoxy group or an optionally hydroxylated alkyl group, and R.sub.2 and R.sub.4 independently of one another denote hydrogen, hydroxyl, alkoxy, alkyl, or phenyl optionally substituted by OH, these compounds having at most two alkyl or alkoxy groups on the quinone ring; if one of the radicals R.sub.1, R.sub.2, R.sub.3 or R.sub.4 denotes a methyl, hydroxyl or methoxy group, at least one of the other substituents is different from hydrogen, and if two of these substituents R.sub.1, R.sub.2, R.sub.3 or R.sub.4 are identical and located in the para-position relative to one another and denote hydroxyl or methoxy, at least one of the other two substituents is different from hydrogen.
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.
摘要:
Composition in the form of a shampoo based on anthralin or one of its derivatives.This composition contains in aqueous solution or dispersion:anthralin or one of its derivatives,at least one fatty acid alkyl ester, the fatty acid having 5 to 8 carbon atoms and the alkyl radical having 3 to 18 carbon atoms,at least one anionic or nonionic surfactant,that composition being stable to oxidation for approximately one week when stored at a temperature of approximately +4.degree. C.This composition is used in the treatment of the scalp, particularly for psoriasis.
摘要:
A cosmetic composition in the form of a powder for dyeing hair when diluted comprising a mixture of (1) particles of a vegetable substance of the non-exhausted type and not naturally containing dye principles wherein at least 95 percent by weight of the particles of said vegetable substance have a granulometry lower than 180 microns, (2) at least one direct dye and (3) at least one solid diluent, the said solid diluent being such that it exhibits in a 40% aqueous solution or dispersion a viscosity lower than or equal to 150 centipoises at ambient temperature.
摘要:
To prepare an aqueous dispersion of lamellar lipid vesicles, at least one lipid is dissolved in at least one water-immiscible organic solvent; the organic phase thus obtained is added to an aqueous phase in such amounts that a dispersion of the oil-in-water type is obtained by vigorous stirring; the evaporation of the solvent(s) is carried out with vigorous stirring, the continuous phase of the dispersion always remaining the aqueous phase; and, should it become necessary, the dispersion is concentrated. The process can be carried out at low temperature (of the order of 35.degree. to 55.degree. C.), which makes it possible to encapsulate in the aqueous phase or to introduce into the vesicle sheets heat-sensitive active substances; the lipid concentration in the organic phase can reach up to 50% by weight.
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.
摘要:
A cosmetic composition for application to human hair or skin contains as a thickening or opacifying agent therefore, the residue of a plant extracted to remove all of at least one of its dye, essential oil, olfactory or therapeutic or cosmetic active principles. The residue is in powder form having a granulometry less than 125 microns and is present in said composition in an amount ranging from 2 to 95 percent by weight based on the total weight of said composition.
摘要:
A cosmetic composition for the treatment of the hair and skin comprises at least 5 weight percent of pulverized particles of at least one plant. The particles have a granulometry lower than 125 microns. The composition also includes a cohesion agent in an amount to maintain the homogeneity of the composition.
