Patent number: 10415004Abstract: 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.Type: GrantFiled: April 17, 2018Date of Patent: September 17, 2019Assignee: Ecolab USA Inc.Inventors: Stephen B. Christensen, Joanna A. Pham, Jessica Bull

Patent number: 8314057Abstract: 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.Type: GrantFiled: September 17, 2010Date of Patent: November 20, 2012Assignee: Ecolab USA Inc.Inventors: Stephen B. Christensen, Joanna A. Pham, Victor Fuk-Pong Man, Michael Charles DeNoma, Yvonne Marie Killeen, Steven Eugene Lentsch, Dawn Lock
