The two anionic extended surfactants evaluated were sodium alkyl polypropylene oxide sulfate(R-(PO) -so4Na with alkyl(R) group consisting of branched hydrocarbon chain with 14-15 car bons(C and with five propylene oxide units known as Alfoterra145-5PO which was 28.7x active units known which was 29.xactive. These surfactants were donated from Sasol North Americalnc. The non- ionic surfactant evaluated was coconut fatty acid diethanolamine(Comperlan KD) which was 98x active. This surfactant was pur- chased from Cognis, Thailand. The palm kernel oil and palm kernel seed used in this work were donated from Lamsoong Thailand com pany and used as received during July to December 2006.
