SURFACTANT

PROBLEM TO BE SOLVED: To provide a surfactant with a reduced variation in surface activity. SOLUTION: The surfactant comprises (A) a hydrophilic silica of a specific surface area of 100-450 m2/g, measured by the BET method (JIS R1626-1996), (D) a polyoxyalkylene compound and (C) a hydrophobic silica...

description	PROBLEM TO BE SOLVED: To provide a surfactant with a reduced variation in surface activity. SOLUTION: The surfactant comprises (A) a hydrophilic silica of a specific surface area of 100-450 m2/g, measured by the BET method (JIS R1626-1996), (D) a polyoxyalkylene compound and (C) a hydrophobic silica. (D) preferably contains one or more of compounds of formulae (1) and (2) (wherein R is a 1-6C linear alkyl or alkenyl group or a hydrogen atom; OAs are each a 3-4C oxyalkylene group; n is a 10-100 integer; and m is 0 or 1). More preferably, the surfactant contains (B) water in a B/A weight ratio of 0.1-20. COPYRIGHT: (C)2006,JPO&NCIPI
