Low in order to solubilize the solubility molecule the new non ionicity surface active agent

摘要

General formula (i):CH₃ - (CH₂) _x-CH- (CH₂) _y-CO- [-o-r3-] _z-O-R1R2-O (i)[In formula, for example R₁ is methyl, R₂ C₁₄ - C₂₂ acyls which are substituted optionally, is alkyl, or arukeniru, R₃ is ethylene, x is 2 - 12, the polyoxyalkylene glycol hydroxy fatty acid derivative or the mono alkylation which possesses the substituent of specification in the polyoxyalkylene/alkyl polyoxyalkylene chain and with respect to hydroxy position of the hydroxy fatty acid of specification y is, is and 7 - 17 (25 - 57 is] follows x+y) 3 - 19 and z, has the chain length of the repetitive monomer unit 25 - 455Being the non ionicity surface active agent whose shape of the polyoxyalkylene glycol hydroxy fatty acid derivative is new; The non ionicity surface active agent which is drawn up profitably by accompanying enzyme process method, the formulation which includes those, as a solubilizer the process method which accompanies those uses and the hydrolase in order to draw up those.
