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.
