ABSTRACT:
Mixtures of alkoxylated ether sulfate anionic surfactants of this invention are prepared by conventional procedures, e.g., oxyalkylation with propylene oxide or 1,2-butylene oxide of a plasticizer range linear or branched "oxo" alcohol; optionally followed by oxyalkylation with ethylene oxide or with a mixture of ethylene oxide and higher alkylene oxide; sulfation of the alkoxylated product; and neutralization of the sulfated derivative. The alkoxylated ether sulfate anionic surfactant compositions of the present invention are liquids which exhibit superior detergency to polyester fabrics, excellent hard water stability, low foaming, low odor, and exhibit excellent compatibility with non-ionic and other surfactants in detergent formulations. The compositions of the invention are prepared as concentrates containing high proportions of active ingredients which are capable of being diluted with water without formation of a gel phase or lumps and as surfactants exhibit properties comparable to commercial surfactants prepared from "detergent" range alcohols.
