  • Patent number: 8658588
    Abstract: A composition for cleaning hard surfaces which is self-adhering to a wet or dry hard surface through a plurality of flows of water thereover. The composition is a gel having a viscosity of about 600,000 cP to about 1,500,000 cP and is capable of being manually applied, i.e., in absence of an applicating dispenser, to a hard surface. The gel composition with high viscosity provides for continuous cleaning until depletion, or may be used for one-time cleaning at any time between application of the composition to a hard surface and depletion of the gel composition.

  • Publication number: 20130259943
    Abstract: A stable, high VOC, single phase, non-aqueous liquid aerosol composition having enhanced dispersion based on reduced particle size and increased evaporation rate to result in improved active ingredient dispersion, slower settling in air and less residue on surfaces. The composition includes at least one hydrocarbon propellant, at least one active ingredient and a solvent blend. The solvent blend includes at least one low volatility solvent and at least one high volatility solvent wherein each has a defined vapor pressure and Hansen solubility parameter. The composition upon dispersion as a spray has an aerosol particle size of less than 30 microns.

  • Patent number: 8328894
    Abstract: A device is provided that is capable of circulating air throughout a personal space as well as collecting and preventing the build up of dust and other particulate matter by drawing in air from the surrounding environment and removing some dust, allergens and other such particulate matter therefrom. The filtered air is then expelled out of the device and back into the surrounding environment. The device includes a housing defining an interior space having a motor and fan assembly disposed therein. The housing includes an inlet with a filter provided therein such that air drawn in through the inlet is filtered. The air is then expelled through a circumferentially disposed outlet. The filter element preferably includes a lock and key system configured to prevent operation of the device in the absence of a properly keyed filter.
