摘要:
The invention relates to the cosmetic use of polysaccharide compounds containing non-polymer siloxane graft(s) that may be obtained by reacting a polysaccharide and a siloxane compound corresponding to formula (I), especially for the cosmetic treatment of keratin materials. The invention also relates to compositions comprising the said polysaccharide compounds in a cosmetically acceptable medium, and also to certain novel polysaccharide compounds containing non-polymer siloxane graft(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.
