Abstract

Isotridecanol block alkoxylates I ##STR1## where R is isotridecyl, PA0 m is 2 when n is 3 or 4, or PA0 m is 3 or 4 when n is 2, and PA0 x and y are independently of each other from 1 to 20, PA0 subject to the proviso that x is not less than y when m=2 and n=3 or 4, PA0 are useful as low-foam or foam-suppressing surfactants, especially in detergent and cleaner formulations and for chemical-technical applications.
