Abstract
Abstract Polyglycol esters which can be obtained by partially esterifying an oxalkylate of 1,1,1-trimethylolethane or pentaerythritol with a mixture of ethylene oxide and propylene oxide in the molar ratio of from 2:1 to 4:1 with sub-stoichiometrical amounts of a carboxylic acid having from 10 to 20 carbon atoms or an acylating derivative of such a carboxylic acid may be used as surface-active agents. The polyglycol esters increase and/or stabilize the viscosity of aqueous systems and are also suitable as emulsifying agents.
