Abstract
A surfactant composition for a foamed sand including 80 to 99.8 mass % of a compound (A) represented by formula (1); 0.1 to 10 mass % of a compound (B) represented by formula (2); and 0.1 to 10 mass % of an amphoteric surfactant (C): R1O-(EO)n—SO3M1 (1) wherein R1 represents a hydrocarbon group having 6 to 22 carbons, EO represents oxyethylene group, n is 1 to 10, and M1 represents an alkali metal, an alkaline earth metal, ammonium or an organic ammonium; R2O—SO3M2 (2) wherein R2 represents a hydrocarbon group having 6 to 22 carbons, and M2 represents an alkali metal, an alkaline earth metal, ammonium or an organic ammonium.
Claims1
