NON-IONIC SURFACE ACTIVE AGENTS CONTAINING THE MOLECULE OF A CARBOHYDRATE SELECTED FROM THE GROUP CONSISTING OF WATER-SOLUBLE, INCLUDING COLLOIDALLY SOLUBLE HEXOSE-UNIT MONOSACCHARIDES AND WATER-SOLUBLE, INCLUDING COLLOIDALLY SOLUBLE HEXOSE UNIT POLYSACCHARIDES IN WHICH THE HYDROGEN ATOM OF AT LEAST ONE OH GROUP OF THE CARBOHYDRATE IS REPLACED BY A GROUP HAVING THE GENERAL FORMULA I WHEREIN R1 STANDS FOR A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC AND CYCLOALIPHATIC HYDROCARBON RADICALS, AND R2 STANDS FOR A MEMBER SELECTED FROM THE GROUP CONSISTING OF HYDROCARBON RADICALS AND HYDROGEN; THE NUMBER OF SAID GROUPS OF FORMULA I BEING AT LEAST 1 IN THE WHOLE MOLECULE, AND AT MOST 2 CALCULATED PER HEXOSE UNIT OF THE MOLECULE, THE AGGREGATE NUMBER OF CARBON ATOMS OF R1 AND R2, CALCULATED PER HEXOSE UNIT, BEING FROM 10 TO 19 WHEN SAID CARBOHYDRATE IS A MONOSACCHARIDE, AND THE AGGREGATE NUMBER OF CARBON ATOMS OF R1 AND R2, CALCULATED PER HEXOSE UNIT, BEING FROM 4 TO 19 WHEN SAID CALCULATE IS A POLYSACCHARIDE.
