Definitions

  • the present invention relates to laundry detergent compositions with improved stability of water insoluble brightener that contain mid-branched primary alkyl sulfate.
  • Optical brighteners have been known in the art for use in laundry detergent compositions and when deposited on fabrics, provide a visual benefit. These are desirable to include in liquid laundry detergent compositions as they may make white clothing look whiter and/or make colored clothing appear brighter, and therefore, newer. Optical brighteners which are more insoluble in water are preferable for deposition on fabrics. However, such brighteners are characteristically more difficult to stably formulate in aqueous liquid laundry compositions.
  • MEA monoethanolamine
  • MAS surfactants Mid-branched primary alkyl sulfate surfactants having an average carbon chain length of from about 14 to about 17
  • MBAS surfactants exhibit good cleaning properties when used as a main chassis surfactant as well as when used in a lower level in combination with other surfactants or in low surfactant detergent compositions.
  • the MBAS surfactants with a carbon chain length of about 16 to 17 also referred to as "HSAS surfactants" generally provide better cleaning than those of other chain-lengths.
  • use of the HSAS surfactants typically results in an increase in the hydrophobicity of the surfactant system. Without being bound by theory, it has been surprising found that this increased hydrophobicity of the surfactant system appears to lead to decreased brightener stability, even when combined with water insoluble brighteners. One of ordinary skill would have contrarily expected better solubility of the water insoluble brightener with increased surfactant system hydrophobicity.
