Surfactant detergent composition containing mid-chain branched surfactants

Abstract

A detergent composition containing a selected surfactant system is disclosed which has improved performance particularly under high water hardness and low temperature wash water conditions. The detergent composition includes a mid-chain branched primary alkyl sulfate surfactant and a linear alkyl benzene sulfonate surfactant and a linear alkyl sulfate surfactant in optimally selected relative proportions. combination. Additionally, the detergent compositions contain up to about 5% alkyl ethoxylated sulfate surfactant and up to about 5% nonionic surfactant while having such relatively low amounts of nonionic surfactant. , unexpectedly has improved performance.

Description

field of invention [0001] The present invention generally relates to improved performance detergent compositions containing selected surfactant systems. More specifically, the detergent composition includes a mid-chain branched primary alkyl sulfate surfactant in combination with a linear alkylbenzene sulfonate surfactant and a linear alkyl sulfate surfactant. An agent system which provides compositions with improved cleaning performance, especially under low water temperature wash conditions. Background of the invention [0002] Conventional detersive surfactants include molecules with water-solubilizing substituents (hydrophilic groups) and lipophilic substituents (hydrophobic groups). Such surfactants generally include hydrophilic groups, such as carboxylate, sulfate, sulfonate, amine oxide, polyoxyethylene, etc., attached to an alkyl, alkenyl or alkenyl group usually containing about 10 to about 20 carbon atoms. Alkaryl hydrophobic group. Theref...
