摘要:
Use of at least one material chosen from homopolymers and salts thereof of formula (I), defined herein, for moisturizing the skin, mucous membranes and/or keratin fibres, and/or as a moisturizer and/or emollient, for the skin, mucous membranes and/or keratin fibres. The invention also relates to a cosmetic or pharmaceutical composition for moisturizing the skin, mucous membranes and/or keratin fibres, comprising at least one material chosen from homopolymers and salts thereof of formula (I).
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:
An O-acyl product derived from glucose which may be obtained by partial or total esterification of glucose and of vitamin F, comprising a mixture of esters, for example, monoesters, of glucose and of at least one acid chosen from linoleic acid, oleic acid, palmitic acid and stearic acid, compositions, for example, cosmetic and pharmaceutical compositions, comprising this novel derivative, and their use for improving the condition of head hair and/or other hairs, and, for example, for reducing and/or impeding the loss of head hair and/or other hairs, and/or for inducing and/or stimulating hair growth, as well as a process for preparing O-acyl derivatives mainly in position 6 of glucose, comprising preparing a mixed anhydride by reacting a carboxylic acid with a trimethylacetyl halide, followed by reacting said mixed anhydride formed with glucose.
摘要:
The disclosure provides ready-to-use cosmetic compositions for relaxing keratin fibers in a cosmetically acceptable medium free of polyhydroxylated alkane, containing, as a relaxing agent, an imine not belonging to the hydroxide family. The disclosure also provides kits containing compartments to be placed in contact to form the ready-to-use compositions, and processes using these compositions.
摘要:
The present invention relates to novel amphoteric polysaccharide compounds containing aldehyde function(s) corresponding to the formula (I): P—(O—(Y)p-CAT)m in which: P represents a polysaccharide chain, the said chain hearing one or more aldehyde functions and optionally one or more groups —COOV, this group possibly being obtained during the oxidation of certain carbon atoms of a saccharide unit, Y represents a linear or branched, saturated or unsaturated, optionally hydroxylated divalent C1-C8 divalent hydrocarbon-based group comprising at least one ether and/or amine function in the hydrocarbon-based chain, or a group —Si(R)2—[O—Si(R)2]q-Z-; p is O or 1, and CAT represents an ammonium group or a cationic polymer chain obtained by grafting and polymerization of ethylenic monomers bearing an ammonium function. The invention also relates to their use in cosmetics and to compositions comprising them.
摘要:
An embodiment disclosed herein is the use in cosmetics of at least one dithiol comprising an amide functional group for transforming the shape of the hair. Also disclosed herein are cosmetic compositions comprising at least one dithiol comprising an amide functional group in a cosmetically acceptable medium.
摘要:
The invention concerns the use in a cosmetic composition of at least a poly-aminoacid of general formula (1) in which X is —O—, —S— or —NR3; R1 represents in particular a hydrogen atom or a C114 C40 alkyl radical; R2 represents in particular a hydrogen atom or an optionally substituted alkyl radical; R3 represents a hydrogen atom or an alkyl radical; R4 represents a hydrogen atom or a radical such as NH2, OH, SH, —CHOHCH3, —CONH2; n is a number greater than 1 such that the poly-aminoacid derivative molecular weight ranges between 200 and 200000. The invention also concerns the use of said derivatives for keratinous fibre strengthening and care. (I)
