摘要:
The present invention relates to a deodorant composition, in particular a cosmetic composition, comprising, as odor-absorbing agent, at least one water-soluble zinc salt, and preferably zinc pyrrolidonecarboxylate, to the use of the composition for the manufacture of cosmetic products intended for human topical application, in particular deodorants, to a process for treating human axillary smells, and to the use of a water-soluble zinc salt as, preferably sole, an odor-absorbing agent in a deodorant composition. The composition is particularly intended for formulations comprising an aqueous phase: aqueous lotions, emulsions and preferably water-in-silicone emulsions.

According to this process, one effects a stereospecific reduction of the two hydroxyl groups of an ether-diol by a mixture (titanium trichloride, lithium aluminum hydride) at a temperature between 5.degree. C. and about 40.degree. C. and that optionally, one converts the resulting ether into vitamin A, retinol or retinoic acid.Application to the synthesis of all-trans compounds selected from the group consisting of vitamin A and its ethers, retinol and retinoic acid, and their 13-cis isomers.

An anti-oxidant system contains, in combination, at least one stabilized ascorbyl ester, at least one tocopherol or a mixture of tocopherols, or cafeic acid or a derivative thereof, at least one complexing agent and at least one non-thiol polypeptide. The anti-oxidant system is employed to stabilize fatty bodies and cosmetic compositions.
