  • Publication number: 20020011584
    Abstract: Stable, aqueous compositions for treating surfaces, especially fabrics, comprise: a relatively low molecular weight polyalkyleneoxide polysiloxane surfactant; a buffering agent to maintain the pH of the composition in the range of from about 4 to about 10, preferably from about 5 to about 9.5, and more preferably from about 6 to about 9; and an aqueous carrier. The compositions can further comprise catoinic surfactants to further enhance the spreading and/or fabric penetration ability of the compositions. The compositions can further comprise a variety of other optional ingredients. Methods of treating surfaces include methods wherein the compositions are contacted with surfaces, especially fabrics, to reduce malodor impression on the surfaces and/or reduce the appearance of wrinkles in fabrics.

  • Patent number: 6019252
    Abstract: A plastic container (liner) that fits closely inside a conventional aerosol can to provide protection for the can. The completed liner/container and can assembly is filled with, e.g., an acidic detergent composition and aerosol propellant. Inwardly curved channels are provided linearly down the sides of the plastic container to allow air to escape when the plastic liner/container is inserted into the body of the aerosol can before the top is added to the can. The plastic container is molded into a collar around the valve opening in the top of the can after the top is attached to the body to form a "pre-assembly" container that is then filled. An acid compatible valve assembly is attached through the valve opening to seal the can, and propellant is added.
