摘要:
A mineral or organic particle-based product comprising an indoline product, a method for preparing same, and the use thereof in cosmetics. The product is a powder consisting of mineral or organic particles smaller than 200 microns, and comprises, in and/or on the particles, an indoline product obtained by oxidative polymerization using at least one indoline.
摘要:
The invention relates to the use of a 5,6-dihydroxyindoline corresponding to the formula (I): ##STR1## in which R represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group, as well as the acid addition salts of these compounds for dyeing keratinous materials, in particular human keratinous materials,and to the tinctorial compositions and methods employed.
摘要:
The invention relates to benzylidenecamphor derivatives of formula: ##STR1## where R is hydrogen or a tert-butyl residue, R.sub.1 is a C.sub.1 -C.sub.8 alkyl or alkoxy residue, and R.sub.2 and R.sub.3 denote hydrogen or hydroxyl, at least one of the two being hydroxyl, to a process for preparing them and to their uses as antioxidants, broad-band sunscreens and medicinal products for the preventive treatment of skin allergies and inflammations as well as for the prevention of certain cancers.
摘要:
The present invention relates to 1-substituted derivatives of 4-methoxy-2,3,6-trimethylbenzene which are useful in cosmetic or pharmaceutical preparations for use in the treamtnet of dermatological complaints connected with a keratinisation disorder, dermatological complaints having an inflammatory and/or immuno-alleric component or ophthalmological complaints.
摘要:
The invention provides a compound of formula (II): ##STR1## and the corresponding isomers and salts; in this formula, a equals 0 or 1; R.sub.1 and R.sub.2 represent, independently, H or a C.sub.1 -C.sub.4 alkyl group; R.sub.3 denotes --C.tbd.N; oxazolinyl; --CH.sub.2 OR.sub.4 (R.sub.4 =H, C.sub.1 -C.sub.4 alkyl, C.sub.2 -C.sub.6 mono- or poly-hydroxyalkyl, cyclopentyl or cyclohexyl, or --OR.sub.4 =tetrahydropyranyl); --COR.sub.5 (R.sub.5 =H, C.sub.1 -C.sub.4 alkyl, --NR'R" where R' and R" have various meanings); --OR.sub.6 (R.sub.6 =H, C.sub.1 -C.sub.18 alkyl, C.sub.2 -C.sub.3 monohydroxyalkyl or C.sub.3 -C.sub.6 polyhydroxyalkyl with 2-5 OH groups), which has useful medicinal and cosmetic applications.
摘要:
The present invention relates to a composition for the coloring of keratin fibres, notably hair, that comprises a phenoxazinone dye of formula (I) as well as the use of this dye for hair coloring. The invention thus makes it possible to obtain coloration that respects the nature of the hair and offers strong shades, which are resistant and have low selectivity.

摘要:
The present invention relates to a dye composition comprising, in a suitable dyeing medium, at least one hydrophobic direct dye whose logP is greater than 2, the suitable medium containing water, and at least one propylene glycol derivative of formula (I) below R1(OC3H6)nOR2 This composition makes it possible to obtain strong colorations. Furthermore, the coloration obtained makes it possible to achieve or even exceed the fastness obtained by oxidation dyeing.
摘要:
The invention relates to a composition for dyeing human keratin fibers, comprising, in a cosmetically acceptable medium, one or more cationic direct dyes comprising at least one carbon-carbon triple bond, for instance dyes of formula (I), (II) or (III) below: in which A1, A2 and A3, independently of each other, correspond to a cationic heterocyclic group and B1, B2 and B3, independently of each other, correspond to a particular aromatic nucleus; n may be equal to 1 or 2.
摘要:
A subject-matter of the present invention is the use, in the direct dyeing of keratinous fibers, of at least one direct dye and of a specific cationic hydrotropic agent of formula: in which X represents CH or N+R6 with R6 representing a C1-C10 alkyl, R1 represents either a hydrogen or a C1-C10 alkyl, if X represents N+R6, or (CH2)nN+R3R4R5 with R3, R4 and R5, which are identical or different, representing a C1-C10 alkyl and n representing an integer between 0 and 12, if X represents CH; R2 represents a C1-C4 alkyl; p has a value 0 or 1; the electrical neutrality of the compound being provided by a cosmetically acceptable anion or a mixture of cosmetically acceptable anions. The invention likewise relates to a dyeing composition comprising at least one dye and such a cationic hydrotrope and to colouring processes employing this dyeing composition.
