Use of 3-substituted stilbene derivatives as deodorizing active principles in cosmetic compositions

摘要

A 3-substituted stilbene derivative (I) is used as a deodorant in a cosmetic compositions. Certain specific stilbene derivative compounds are new. The stilbene derivatives used are of formula (I) A = H or OR2; R1 and R2 = H, 1-4C alkyl, R3-CO-, PO(OX1)(OX2), SO2(OX3), glycosyl or uronyl; R3 = 1-30C hydrocarbon radical that may be saturated or unsaturated and may be hydroxylated, or carboxylated; R4 and R5 = H or OH; X1, X2, and X3 = H, monovalent alkali metal cation, ammonium, and X1 and/or X2 may also be a divalent metal cation. Preferably (I) is natural or synthetic 3,5-dihydroxy stilbene (Pinosylvine), 3-hydroxy stilbene, or 3,5,3',4'-tetrahydroxy stilbene. The compositions preferably contain 0.001 - 10%, especially 0.01 - 5% of the compositions other deodorant or antitranspirant ingredients. Independent claims cover compounds of formula (I) per se where A, X1, X2, and X3 are as defined, R1 and R2 = R3CO, PO(OX1)(OX2), SO2(OX3), glycosyl or uronyl, and R3 has 4 - 30 C atoms.
