ABSTRACT:
Carboxyfunctional silicone glycols are made by equilibration at elevated temperatures of silicone glycols in which the glycol radical or radicals are bonded to silicon with an Si--C linkage and carboxyfunctional siloxanes in which the carboxy radical or radicals are bonded to silicon with an Si--C linkage in the presence of an acid catalyst which is capable of breaking Si--O linkages but not Si--C linkages. The carboxyfunctional silicone glycols so produced are of the type which are useful as profoamers, surfactants, spreading agents for active chemicals, such as pesticides, hydrophilizing treatments for fabrics and hair, as emollients in cosmetic formulations and as chelates.
