摘要:
A cosmetic or dermatological system includes a packaging and dispenser device containing one or more compositions from which the dispensed preparation is prepared, a surroundings sensor that is suitable for delivering at least information associated with a physical magnitude of the surrounding environment of the device, an adjustment system that is coupled to or suitable for coupling to the packaging and dispenser device, and that enables at least one characteristic of the dispensed preparation to be varied, and a processor for automatically controlling the adjustment system as a function of data delivered by the surroundings sensor or for informing the user, as a function of the data, about an action to be exerted on the adjustment system.
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:
A dentifrice composition contains, as an anti-caries agent, at least one water-soluble polycationic polymer, containing units which contain at least one quaternized nitrogen which is part of the macrochain, and in which at least 5% of the cationic charges are balanced by fluoride anions; and use of such polycationic polymer fluorides as anti-caries agents.
摘要:
New compositions for the treatment of keratin material, in particular human hair, skin and nails are provided comprising a combination of a cationic polymer with an anionic polymer. Surprisingly the anionic polymer can be retained well on the hair, even after rinsing, when applied with the cationic polymer.
摘要:
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 scalp comprises in a cosmetically acceptable vehicle a combination of a water soluble polyamide of the poly-beta-alanine type and a nicotinic derivative selected from nicotinic acid or an ester thereof. This composition is employed in a process for improving the regrowth of hair and for delaying or retarding the appearance of an oily aspect of the hair.
摘要:
A capillary cosmetic composition for washing or disentangling hair comprises in an appropriate cosmetic vehicle at least one plant extract, the active principle of which is at least one saponin and at least one cationic polymer.
摘要:
A cosmetic composition for application to the hair to delay the appearance of an oily aspect of the hair contains a water-soluble polymer of the poly-.beta.-alanine type.
摘要:
The invention relates to a dyeing composition for keratinous fibres containing at least one 4-bis(.beta.-hydroxyethyl)amino-2-nitro-1-(N-substituted amino)benzene compound in which the substitution is C.sub.1 -C.sub.3 alkyl or .beta.-hydroxyethyl; this composition contains as co-solubilization agent at least one dye of formula (II) ##STR1## in which formula: R.sub.2 denotes a C.sub.2 -C.sub.3 hydroxyalkyl group;R.sub.3 denotes a C.sub.2 -C.sub.3 hydroxyalkyl group; with the proviso that, if R.sub.3 =CH.sub.2 CH.sub.2 OH, R.sub.2 is necessarily an .alpha.-hydroxyethyl or hydroxypropyl radical.
