摘要:
Aminated .gamma.-dialdehyde and the quaternary ammonium salts thereof are prepared by acid hydrolysis of their respective corresponding 2,5-dialkoxy 3-amino 4-hydroxy tetrahydrofurans or by acid hydrolysis of their respective corresponding tetraalkyl acetals. The aminated .gamma.-dialdehydes and the quaternary ammonium salts thereof are usefully employed in cosmetic compositions to tan the skin or to strengthen or restructure the hair.
摘要:
A heterocyclic aluminum compound of the formula ##EQU1## wherein n is 1 or 2. When n is 1, Z is --CH=CH--. When n is 2, Z is either --(CH.sub.2).sub.m wherein m is 0-6, or a heteroatom selected from --O--, --S--, >SO, >SO.sub.2 or >N--COR' where R' is an aliphatic hydrocarbon of 1-17 carbon atoms, --(CH.sub.2).sub.q --C.sub.6 H.sub.5 where q is 0 or 1, styryl, diphenyl methyl or phenyl optionally substituted by chlorine, fluorine, methyl and alkoxy having 1-4 carbon atoms. The compound can be prepared by reacting isopropyl aluminate with an .omega.-diol of the formula ##EQU2## wherein Z has the meaning given above and then reacting the resulting product with dry HCl or an acyl chloride of the formula R'--COCl wherein R' has the meaning given above. The heterocyclic aluminum compound exhibits antiperspirant activity. It can be used in cosmetic antiperspirant compositions comprising a cosmetic vehicle and about 0.2-30 weight percent thereof based on the weight of said composition.

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 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 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 process is disclosed for the preparation of bis-(N-oxypyridyl-thio) derivatives of aluminum sulfonates by reacting a bis-isopropylate aluminum derivative of an organic sulfonate with two equivalents of the N-oxide of pyridine-2 thiol. The bis-isopropylate aluminum derivative of the organic sulfonate is formed by reacting the organic sulfonic acid precursor with aluminum isopropylate.
