THE INVENTION RELATES TO COMPOUNDS CHARACTERIZED IN THAT THEY COMPLY WITH THE GENERAL FORMULA: (CF DRAWING IN BOPI) IN WHICH R IS THE HYDROCARBON RADICAL OF A FATTY ACID OF 16 OR 18 CARBON ATOMS, OR ISOSTEARIC ACID OR A MIXTURE OF THESE RADICALS, R A HYDROGEN ATOM OR THE RADICAL: (CF DRAWING IN BOPI) X, Y AND Z ARE WHOLE NUMBERS AND SXYZ A VALUE OF 50 TO 60. THE INVENTION ALSO RELATES TO A PROCESS FOR THE PREPARATION OF THESE COMPOUNDS, CHARACTERIZED BY THE FACT THAT IT IS FIXED BY ADDITION TO GLYCEROL OR 1,2-PROPANEDIOL, IN THE PRESENCE OF USUAL CATALYSTS, AT TEMPERATURES OF 80 TO 150C AND AT HIGH PRESSURE, 50 TO 60 MOLES OF ETHYLENE OXIDE AND THE ADDITIONAL PRODUCT IS ESTERIFIED AT HIGH TEMPERATURES, WITH AT LEAST EQUIVALENT QUANTITIES OF RCOOH RELATING TO THE HYDROXYL GROUPS, OR WHEN TRANSESTERIFIED WITH RCOOCH OR WHICH IS DONE REACT ON RCOCI AND WHETHER THE WATER OR METHANOL RELEASED IN THE REACTION IS SEPARATED OR NEUTRALIZED HYDROGEN CHLORIDE, AS WELL AS THEIR APPLICATION AS THICKENERS, IN PARTICULAR FOR AQUEOUS SOLUTIONS CONTAINING SURFACTANTS AS WELL AS SOLUBILIZERS, IN PARTICULAR FOR COSMETIC COMPOSITIONS. |
