  • Cleaning composition
    Patent number: 7939480
    Abstract: A post-foaming personal cleaning composition in the form of a gel for use in an aerosol container. This composition includes a base material of a surfactant in an amount not less than 7 % by weight and a thickener that is a blend of at least one of glyceryl ester, and a glyceryl ester derivative with at least one of a betaine and a gum. The base material preferably has a viscosity greater than 9,500 cps. The composition also includes a foam forming material, above 9 % by weight of the composition with at least a part of the foam forming material being maintained in suspension in the composition until after the composition is dispensed from the aerosol container. The foam forming material is preferably a saturated aliphatic hydrocarbon having from 4 to 5 carbons and the composition is in the form of a gel prior to inclusion of the foam forming material.
    Type: Grant

  • Cleaning composition
    Patent number: 5804546
    Abstract: A cleaning composition consists of a surfactant and two components for example an acid and a carbonate or bicarbonate. When the two components are mixed together a gas is generated which acts on the surfactant to create a lather. The composition may be disposed in a package having two containers one for each component.
