摘要:
The invention relates to a composition, in particular a cosmetic or dermatological composition, having an aqueous dispersion of vesicles with a lipid membrane, characterized in that the lipid membrane contains at least one carbamate of following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 are defined in the specification.
摘要:
The subject of the invention is a process for the preparation of 2-aminoalkane-1,3,4-triols, in a single stage, preferably a single reduction state, from alkyl 2-hydroxyimino-3-oxo-4-acyloxyalkanoates. The invention makes possible a significant reduction in the number of stages and a marked improvement in the synthesis yields.
摘要:
New lysine derivatives containing a containing an alkylsulphonyl or alkylaminocarbonyl group of formula (I): COOH--CH(NH.sub.2)--(CH.sub.2).sub.4 --NH--X in which X represents an --SO.sub.2 R or --CONHR group, where R represents a linear or branched, saturated or unsaturated, alkyl radical having from 8 to 22 carbon atoms, salts thereof, and mixtures of the derivatives and the salts. A process for the preparation of these derivatives, salts, and mixtures and use of such derivatives, salts, and mixtures, especially in cosmetics. Compositions, especially cosmetic compositions, comprising the derivatives, salts, and mixtures.
摘要:
Lysine derivatives, the salts of the derivatives, their optical isomers of D or L configuration, or their mixtures, the derivatives containing an N.sup..epsilon. -alkoxy or N.sup..epsilon. -alkenoxycarbonyl group of formula: ##STR1## in which: R represents a linear or branched C.sub.13 -C.sub.24 alkyl radical, the C.sub.16 radical being branched, or a linear or branched C.sub.8 -C.sub.24 alkenyl radical. The lysine derivatives are used in cosmetic, pharmaceutical hygiene or food compositions.
摘要:
Linear bi- or tri-enic fatty esters of erythromycin A have the formula ##STR1## wherein one of R and R' represents a linear bi- or tri-enic C.sub.18 acyl radical having an all cis (Z) stereochemical configuration and the other of R and R' represents hydrogen.
摘要:
The invention relates to a process for straightening keratin fibers, comprising: (i) a step in which a straightening composition containing at least two denaturing agents is applied to the keratin fibers, (ii) a step in which the temperature of the keratin fibers is raised, using a heating means, to a temperature of between 110 and 250° C.
摘要:
The invention relates to a cosmetic composition, particularly for hair care, and to a method for cosmetically treating keratin material, particularly the hair, using the compounds of Formula (I), where: —n=1, 2, 3, or 4; —R1, R′1, R2, and R′2 are H, —OH, —NRR′, or a C1-C18 carbon group capable of containing one or more heteroatoms selected from among O, S, and N; and —Z is a multivalent carbon radical optionally substitutable and/or interruptible by specific groupings, it being understood that said radical Z includes at least one heteroatom selected from among N, O, and S.
摘要:
The present disclosure relates to the cosmetic use of grafted polysaccharide compounds comprising at least one non-polymer siloxane graft that may be obtained by reacting a polysaccharide and a siloxane compound corresponding to formula (I), such as for the cosmetic treatment of keratin materials. The disclosure also relates to compositions comprising the grafted polysaccharide compounds in a cosmetically acceptable medium, and also to certain novel grafted polysaccharide compounds comprising at least one non-polymer siloxane graft.
