  • Detergent composition with a selected surfactant system containing a mid-chain branched surfactant
    Patent number: 6380143
    Abstract: A detergent composition, having a selected surfactant system for improved performance, especially under high water hardness and low temperature wash water conditions is disclosed. The detergent composition includes a mid-chain branched primary alkyl sulfate surfactant in combination with a linear alkylbenzene sulfonate surfactant, and linear alkyl sulfate surfactant at optimally selected relative proportions. Additionally, the detergent composition contains up to about 5% of an alkyl ethoxylated sulfate surfactant and up to about 5% of a nonionic surfactant while unexpectedly having improved performance with such relatively low levels of a nonionic surfactant.
    Type: Grant

  • Detergent composition containing mid-chain branched surfactants and an electrolyte for improved performance
    Patent number: 6232282
    Abstract: A detergent composition containing a mixture of linear alkybenzene sulfonate surfactant and mid-chain branched surfactant and an electrolyte is disclosed. The detergent composition includes a mid-chain branched primary alkyl sulfate surfactant and an electrolyte capable of increasing the ionic strength of the compositions resulting in improved performance, especially under low water temperature wash conditions. Typical electrolytes include sodium chloride, magnesium sulfate, calcium carbonate and the like.

  • Low sudsing granular detergent composition containing optimally selected levels of a foam control agent and enzymes
    Patent number: 6169063
    Abstract: A granular detergent composition is provided. The detergent composition comprises at least about 1% by weight of a surfactant and at least about 1% by weight of a builder. The detergent composition also includes from about 6 to about 9% of a particulate foam control agent. In addition, the detergent composition includes from about 0.1 to about 10% of hydrated magnesium sulfate, from about 0.05 to about 0.4% of a protease enzyme, and from about 0.05 to about 0.2% of a cellulase enzyme. The detergent composition produces the low level of foam required for optimal cleaning in washing machines employing a low water wash process.
