Abstract
Blends of N-acyl aminoalkane sulfonates and amphoteric and/or anionic surfactants can be prepared by quenching a molten reaction mixture of an aminoalkane sulfonate amidated with a fatty acid with an aqueous solution comprising an amphoteric and/or anionic surfactant. N--acyl aminoalkane sulfonates can be purified by quenching a molten reaction mixture in isopropanol.
