  • Patent number: 8697622
    Abstract: 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.

  • Patent number: 8580727
    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.

  • Patent number: 6825159
    Abstract: A cleaning composition including a less than fully ionized source of alkalinity within the cleaning composition, a source of chlorine, and a polar carrier. In at least some embodiments, it has been found that chlorine has an increased level of stability within the cleaning composition relative to a second composition having similar components and a similar level of titratable alkalinity, but that includes a fully ionized source of alkalinity as a sole source of alkalinity. Some other embodiments relate to methods of making, and methods of using such cleaning compositions.
