Abstract
In this paper, the physicochemical properties and applicationproperties of two isomers, one with a branched structure (9,10-dihydroxystearic acid ethoxylate) and the another with a linearstructure (stearic acid ethoxylates) were systematically studied.It has been found that: (1) The DHSAE-15 (9,10-dihydroxystearicacid ethoxylated with 15 mean EO units) with a branched struc-ture has better wettability and higher efficiency in reducing sur-face tension than the corresponding linear product SAE-15(stearic acid ethoxylated with a 15 mean EO units); (2) SAE-15 has better detergency than DHASE-15; (3) the spatial config-uration plays a limiting role on the size of the aggregate.
