OXAZOLIUM COMPOUND AND COSMETIC AND SKINNTREATING AGENT CONTAINING THE SAME

摘要

NEW MATERIAL:An oxazolium compound I (R1-R3 are lower to medium-length alkyl; X is anion). EXAMPLE:2-[ ( N-methyl-4-ethoxycarbonylanilino )vinyl ]-3,4-dimethyl-oxazolium iodide. USE:Cosmetics and skin-treating agents. Low toxicity. Characterized by an alkoxycarbonyl group at the para position of a phenyl group. PROCESS:For example, a 3-alkyl-2,4-dimethyloxazolium compound II and a 4-alkoxycarbonyl-N-alkylaniline III are thermally reacted with orthoformic acid ester in the absence of a solvent or in a solvent such as an alcohol to give the compound I.
