Abstract (en)
[origin: US4744923A] Alkylaminopolyethylene glycol ethers corresponding to the following formula <IMAGE> in which R represents a C6-C20 alkyl or alkenyl radical, R1 and R2 are the same or different and represent a C1-C8 alkyl radical and the indices m and n are the same or different and represent a number of from 3 to 20, with the proviso that the sum of m and n is from 5 to 25, are suitable as foam inhibitors for detergent preparations. The foam inhibitors are stable to strong alkalis and strong acids and may be used in concentrations of from 10 to 2500 ppm.
