Disclosed is a ketal having the formula:
wherein R′ and R″ independently are an alkyl group having from 8 to about 20 carbon atoms; m and n independently are an integer of from 1 to about 200; and r and s independently are an integer of from 1 to 3; and the method for preparing the ketal by transketalization using 1,1-dimethoxycyclohexane or 1,1-diethoxycyclohexane with an (alkoxyphenoxy)ethanol type of surfactant. The ketal is at least partially soluble in water.
