Abstract

Abstract ABSTRACT An aqueous carpet cleaning composition which imparts soil and stain repellent properties to the carpet fibers com-prising from about 0.07 to about 1.8 wt-% of a mixture of a perfluoropropionic acid lithium salt of formula I herein or mixture thereof and a perfluoroalkyl phosphate mono/bis-diethanol-amine salt of formula II herein or mixture thereof; from about 0.05 to about 5.0 wt-% of a nonionic, anionic or amphoteric surfactant; 0 to an amount sufficient to provide a pH in the range of from about 4.0 to 9.5 of a pH adjusting agent; and water q.s. to 100 wt-%. F(CF2)n-CH2CH2-S-CH2CH2-COOLi (I) [where n is 6 to 12]
