  • Patent number: 5955414
    Abstract: An aerosol foam cleaning composition for carpets and other soft-furnishings is provided. It has a volatile hydrocarbon propellant, a surfactant, a foam stabilizer polymer, a stain repellent fluorocarbon, an amine oxide foam booster, and water. The foam does not release hydrocarbon propellant at such a rate so as to create flammability problems, yet provides adequate residual stain repellent.

  • Patent number: 5328628
    Abstract: This invention relates to a method of stabilizing liposomes contained in aqueous compositions against lysis by anionic surfactants otherwise known to disrupt and lyse such liposomes by using certain surfactants as stabilizing agents and to the stabilized compositions obtained thereby as well as to a method of making detergent compositions containing such stabilized liposomes and anionic surfactants as well as to the compositions themselves. The compositions can be used as shower gels and shampoos. The liposomes are preferably vesicles derived from natural phospholipids or from synthetic nonionic amphiphilic compounds which are sometimes referred to as "niosomes" and may contain water soluble humectants or vitamins.
