  • Patent number: 10415004
    Abstract: A solid fabric softening composition is disclosed which includes a quaternary ammonium fabric softening compound which is stabilized to form a solid with a mixture of a water soluble organic salt and a medium to long chain carboxylic acid. This stabilizing combination has been shown to effectively form a solid quaternary ammonium based fabric softening composition with up to as much as 70% by weight of quaternary ammonium compound. The formulations are stable at typical storage temperatures of up to 110° F. and provide fabric softening similar to and even superior to other traditional liquid formulations.

  • Publication number: 20130047345
    Abstract: A method for sanitizing, disinfecting and bleaching laundry is provided. The method includes steps of applying an antimicrobial composition at a pH from about 4 to about 9 in an industrial laundry washing machine for effective antimicrobial efficacy, and thereafter applying a detergent use solution at an alkaline pH for removal of soil from the laundry, and optionally applying a bleach activator and/or catalyst to boost the bleaching component of the antimicrobial composition on the laundry, and lastly draining the antimicrobial composition, the detergent use solution and the bleach catalyst composition from the laundry.

  • Patent number: 8314057
    Abstract: The invention discloses synergistic combinations of surfactants blends and cleaning composition. In certain embodiments a surfactant system is disclosed which includes extended anionic surfactants, linker surfactants, and a multiply charged cation component. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. In another embodiment anionic surfactants are combined with a solvent, and amine oxide to remove sunscreen stains. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.
