Quaternary siloxane polymers of the formula: <IMAGE> in which A denotes an alpha , beta -bis-alkylpolysiloxane or a C1-6 hydrocarbon chain which can contain OH groups and can be interrupted by one or more oxygen atoms and/or aromatic rings; R1, R2, R3 and R4, which are identical or different, denote a C1-C6 alkyl or phenyl; R5=methyl, ethyl or -CH2-; R6=C1-C18 alkyl or -CH2-; if R5 and/or R6 denote -CH2-, they form a methylpiperazinium radical or ethylpiperazinium radical, a diethylenediamine radical or a heterocycle with -N-A-N-; Y denotes one of the anions Cl-, Br-, CH3SO3-, <IMAGE> m=1-6; and p=1-50 are disclosed for use, in particular, for treating the hair, nails and skin. They are resistant to several rinses on these substrates. |
