Lipophilic quaternary ammonium salicylate, characterized in that it corresponds to the formula: <IMAGE> in which: (i) R1, R2, R3 and R4, which may be identical or different, denote an alkyl or alkylcycloalkyl radical, optionally substituted or interrupted; (ii) R3 and/or R4 denote(s) a group: R8[OC2H3R7]n [OCH2CHOH-CH2]p in which 0</=n</=4 and p denotes 0 or 1; R8 denotes H or an alkyl, alkenyl, alkylcycloalkyl or alkylaryl radical; (iii) R4 denotes an alkylphenyl radical; (iv), (v) R1 and R2 can form a saturated or unsaturated aromatic or non-aromatic heterocycle; (vi) R1, R2 and R3 form polycyclic derivatives with the nitrogen atoms; R5 denotes a group corresponding to the formula: <IMAGE> in which n is an integer varying between 0 and 10. |
