THE USE OF POLYGLYCOL ETHERS AS FOAM-INHIBITING ADDITIVES IN LOW-FOAM CLEANING AGENTS |
摘要 |
Foam-inhibiting compositions for use in an aqueous solution containing polyethylene glycol ethers corresponding to the following formula R1-O-(CH2CH2O)n-R2 in which R1 represents a linear or branched alkyl or alkenyl radical containing from 8 to 18 carbon atoms, R2 represents an alkyl radical containing from 4 to 8 carbon atoms and n is a number of from 7 to 12, mixtures of the same with a polyglycerol polyethylene glycol alkyl ether of 1 part by weight of polyglycerol having a hydroxyl number in the range of from 900 to 1200 adducted with from 4 to 20 parts by weight of ethylene oxide and etherified at the free hydroxyl groups with alkyls having from 4 to 8 carbon atoms, and their use as foam-inhibiting additives for low-foam cleaning agents. |
