POLYETHYLENE GLYCOL ETHER LOW TEMPERATURE FOAM SUPPRESSING AGENTS IN LOW-FOAM CLEANING AGENTS

摘要

The invention is cleaning compositions containing Polyethylene-glycol ethers of the formula R1-(CH2CH2O)n-R2 (1) in which R1 is a straight-chain or branched alkyl- or alkenyl radical having from 20 to 28 carbon atoms R2 is an alkyl radical having from 4 to 8 carbon atoms and n is an integer from about 6 to about 20 as a foam-suppressing additive. The cleaning compositions are stable over a broad temperature range and have low foaming characteristics particularly at about ambient temperatures.
