Title:
NON-IONIC SURFACTANT AND NON-IONIC SURFACTANT PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/170637
Kind Code:
A1
Abstract:
This non-ionic surfactant is characterized by having a structure represented by general formula (1) and by having an acetal structure formed by a reaction between an alcohol and a hydrophilic vinyl ether. (In general formula (1), R1 is a residue derived from an alcohol, (AO)n are oxyalkylene groups derived from hydrophilic vinyl ethers and are the same or different, n represents the average number of moles of oxyalkylene groups added and is a number 1-400. X is a hydrogen atom or a hydrocarbon group optionally having a substituent.)
