  • Patent number: 6746997
    Abstract: A process for the preparation of mixed ethoxylated alkyl phenol/alkyl phenol ethoxy sulfate surfactants, such surfactants, and detergent formulations incorporating the same. The mixed surfactants are more tolerant of sodium carbonate, allowing greater amounts of sodium carbonate to be used so that the amount of surfactant can be reduced resulting in overall cost savings in the resultant laundry product.

  • Patent number: 5863877
    Abstract: A non-bleaching cleaning composition, e.g. laundry detergent, wherein the solids content comprises at least about 70 wt. % of sodium carbonate, and up to about 12 wt. % of elemental magnesium in the form of a water soluble salt, e.g., magnesium sulfate or magnesium chloride, based on the total weight of the solids composition.
