Emulsifying dispersant and biocidal composition containing same

摘要

An emulsifying dispersant is disclosed which is a nonionic surface active agent substantially free of a terminal primary hydroxyl group, obtained by esterifying or etherifying a terminal hydroxyl group of an alkylene oxide adduct of a hydroxyl compound or an alkylene oxide adduct of a carboxyl compound. This emulsifying dispersant is remarkably effective for preventing decomposition of a biocidal agent and for emulsifying the biocidal agent. A biocidal preparation formed using this emulsifying dispersant has good storage stability and good emulsion stability.
