摘要:
Hydroxy mixed ethers of the general formula (I): R1O[CH2CH2O]xCH2CH(OH)R2 (I) wherein R1 represents a linear or branched, alkyl or alkenyl group having from 4 to 22 carbon atoms; R2 represents a linear or branched, alkyl or alkenyl group having from 2 to 22 carbon atoms; and x represents a number of from 40 to 80, are described along with compositions containing such hydroxy mixed ethers in conjunction with other surfactants. Also described are various anti-foaming uses for such ethers and compositions containing the same.
