High solids, pumpable aqueous compositions of high monoalkyl phosphate ester salt content |
摘要 |
Stable, pumpable aqueous surfactant compositions of water and alkyl phosphate ester salts having a molar ratio of mono- to di- alkyl phosphate esters equal to or greater than 80:20, with the surfactant composition being essentially free of water-soluble alcohol or co-solvent. The pumpable aqueous surfactant compositions have a solids content of about 40% by weight or more and exhibit one or more pumpable regions over a range of pH values for the aqueous surfactant composition.
