As the result of the qualitative and quantitative analysis of the surfactant mixture, the main surfactant of the fast biodegradable detergent which were derived from vegetable oil was Sodium Lauryl Sulfate. The Detergents contained sodium lauryl sulfate, nonionic surfactant, soap, etc, as the rest sufactants. Linear Alkylbenzene Sulfonate and alpha-Olefin Sulfonate which were derived from petroleum were not detected. The biodegradation rate of the detergent prepared from vegetable oil was faster than that of the detergent derived from petroleum stood in 7 days.

A series of four sodium α-sulfo fatty vinyl ester oligomers including sodium α-sulfo lauric acid vinyl ester oligomer, sodium α-sulfo myristic acid vinyl ester oligomer, sodium α-sulfo palmitic acid vinyl ester oligomer and sodium α-sulfo stearic acid vinyl ester oligomer were examined for surface activities such as surface tension, foaming power, foam stability, emulsifying power, dispersion effect, solubilization of orange OT. The critical micelle concentration(CMC) was also evaluated. Consequently, these sodium α-sulfo fatty acid vinyl ester oligomers were shown to have a good cohesive power and dispersion effect.
