NEW MATERIAL:The compound of formula I [m is 0 or 1; when m is 0, R<1> is 1-36C alkyl, alkenyl or phenyl substituted with 1-15C alkyl, R<2> is 2-3C alkylene and n is 0-30; when m is 1, R<1> is 1-22C straight-chain alkyl and n is 0; M is H or salt of alkali metal, alkaline earth metal, alkylamine, alkonolamine or ammonium]. EXAMPLE:Dodecyl glycerolphosphate sodium salt. USE:Raw material for cosmetic and perfumery. It has lower Kraft point and high frothability. PREPARATION:For example, an alkali metal monosalt of a phosphoric acid ester of formula II (M' is alkali metal) is made to react with glycidol of formula III to obtain the alkali metal salt of phosphoric acid ester of formula IV, which is optionally converted to free acid. |
