  • Iso-tridecanolalkoxylates in block form as low-foam or antifoaming surfactants
    Patent number: 6057284
    Abstract: Isotridecanol block alkoxylates I ##STR1## where R is isotridecyl,m is 2 when n is 3 or 4, orm is 3 or 4 when n is 2, andx and y are independently of each other from 1 to 20,subject to the proviso that x is not less than y when m=2 and n=3 or 4,are useful as low-foam or foam-suppressing surfactants, especially in detergent and cleaner formulations and for chemical-technical applications.
