摘要:A cationic oligomer of a saccharide, wherein the saccharide is functionalized by a cationic group, for example an ammonium, phosphonium, imidazolium, or pyridinium group. In a preferred embodiment, the cationic oligomer of a saccharide is a cationic cyclodextrin. There is also provided a use of the cationic oligomer of a saccharide as a chiral agent for resolving enantiomers by a chromatographic method or an asymmetric synthesis.

摘要:The présent invention relates to a composition comprising sarsasapogenin or a plant extract containing it in order to improve the gêneral state of the skin and in particular to improve and/or embellish any part of the body showing a déficit in lipids. More particularly, the invention is directed to a cosmetic method to improve the figure, comprising the step of topically applying to the skin a cosmetic or dermopharmaceutical composition comprising sarsasapogenin to favour the expansion and/or the formation of the subcutaneous adipose tissue, and/or to favour the lipid synthesis in the epidermis.
