Abstract: A washing powder product with high oil dirt removal capacity was prepared based upon various surfactants as well as inorganic builders and accessories.The blended surfactants were composed of sodium linear alkyl benzene sulfonate (LAS),sodium fatty alcohol ether sulphate (AES),dodecyltrimethylammonium bromide (DTAB),and alkyl polyglucoside (APG).The formulation range of surfactants were examined and identified by orthogonal test.Results showed that when the mass fraction of the washing powder product is w(LAS)∶w(AES)∶w(DTAB)∶w(APG)=40∶20∶1∶15,its oil dirt removal rate can reach 98.0%.

Key words: surfactant, blend, orthogonal test, oil dirt removal rate
