For instance, if a surfactant has an HLB = 1, it is considered very oil soluble, while a surfactant with an HLB = 15 is considered to be water soluble. The HLB number is also a measure of the percent ethoxylation (EO) of the respective surfactant. bpp building careers through educationWeb24 giu 2015 · Surfaktan yang digunakan pada proses deresinasi pulp Sumber : Rosen and Dahanayake (2000). 41.
