PROCESS FOR PRODUCING EUTECTIC MIXTURES OF P-HYDROXYBENZOIC ACID ESTERS AND PRODUCT OBTAINED

摘要

THE INVENTION CONCERNS STABLE EMULSIONS OF P-HYDROXYBENZOIC ACID ESTERS. THE EMULSION OF THE INVENTION, OF THE OIL-IN-WATER TYPE, IS FORMED ABOUT 10 A 60 BY WEIGHT OF EUTECTIC OIL CONTAINING MIXED THREE OR MORE THAN THREE ALKYLIC ESTERS OF P-HYDROXYBENZOIC ACID, ABOUT 1.5 TO 5.0 BY WEIGHT OF AN EMULSIFYING AGENT WHICH MAY BE GELATINE, CASEIN, COLLAGEN, GLYCERYLE OLEATE, AN AMMONIUM OR SODIUM SALT OF A NONYLPHENOXYPOLY (ETHYLENEOXY) ETHANOL SULFURIC ESTER OR THEIR MIXTURES AND ABOUT 3 TO 10 BY WEIGHT OF SORBITOL, THE REST BEING WATER. IT ALSO CONCERNS THE PREPARATION OF THESE EMULSIONS. / P P THE EMULSIONS OF THE INVENTION ARE HEDLED WITH ANTIMICROBIAL ACTIVITY. / P
