Patent number: 8697622Abstract: Synergistic combinations of extended chain surfactants and co-surfactants, emulsions or microemulsions and cleaning compositions incorporating the same are provided. In certain embodiments a surfactant system is disclosed which includes extended nonionic surfactants, and a linker surfactant. This system forms stable emulsions or microemulsions with oils, including non-trans fats and fatty acids and these emulsions or microemulsions are stable, irreversible and can be created at low temperature. The cleaning compositions may include the surfactant system alone, a stable emulsion or microemulsion with oil and the surfactant system, a pre-spotter or other pre-treatment or soft surface and hard surface cleaning compositions comprising the surfactant combination.Type: GrantFiled: September 17, 2010Date of Patent: April 15, 2014Assignee: Ecolab USA Inc.Inventors: Victor Fuk-Pong Man, Yvonne Marie Killeen, Steven Eugene Lentsch, Michael Charles DeNoma

Patent number: 8580727Abstract: 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 12, 2013Assignee: Ecolab USA Inc.Inventors: Victor Fuk-Pong Man, Michael Charles DeNoma, Yvonne Marie Killeen, Steven Eugene Lentsch
