Abstract
Aqueous cleaning and surface treatment compositions for imparting oil and water repellency to treated surfaces which comprise: PA1 (a) fluoroaliphatic radical-containing poly(oxyalkylene) compound; PA1 (b) anti-resoiling composition; PA1 (c) anionic surfactant compound, preferably one or more selected from alkyl sulfates, alkyl benzene sulfates, and alkane sulfonates as well as salts thereof; PA1 (d) organic solvent; PA1 (e) citric acid salts, preferably one or more anhydrous and dihydrous sodium citrates PA1 (f) water wherein the are at a neutral or alkaline pH, especially from about 8 to about 10. The compositions are particularly shelf stable, and exhibit excellent shelf stability in pressurized aerosol containers.
