Surfactants having propane sulfonate group were prepared from fatty alcohols, acids, amides and amines.
Surface active properties of their aqueous solutions were examined for surface tension, foaming-, penetrating-, emulsifying powers, hard water resistance and CMC.
In general, their CMG's were lower than those of sodium alkyl-sulfates, and their surface active properties were excellent even at lower concentrations.
As to the relationship between the alkylchain length in these derivatives and the surface active properties, lower surface tension was obtained by C14-and C16-derivatives, excellent emulsifying property by C18-derivatives, and superior foaming and penetrating powers by C12- and C18F1-derivatives.
