Abstract
Aqueous thixotropic foam-producing chemical compositions are presented which are comprised of an anionic sulfonate or sulfate surfactant, a fatty acid having 10-30 carbon atoms, an acrylic-based thixotropic thickener, an acrylic acid polymer processing aide and a base present in a concentration sufficiently high to neutralize all of the acid components of the mixture and adjust the pH to above 7.5. The thixotropic foam-producing compositions are useful for producing thixotropic foams which have the ability to resist slumping on sloped surfaces. Also disclosed is a process for mixing highly viscous, low density chemical foaming compositions with water without causing foaming of the resulting mixture.
