  • Publication number: 20160121011
    Abstract: Aerosol compositions propelled by compressed gas providing enhanced intensity of one or more active components (e.g., fragrance, malodor counteractant, insecticide, disinfectant, or antimicrobial) over an extended period of time in the environment of use consistently over the life of the product. This is provided by a selected combination of spray rate and average particle size of the composition. The increased intensity over time can be further enhanced by further selection of the initial and terminal pressure under which the composition is maintained, and the pressure drop ratio, with respect to the composition product and a suitable dispensing container.

  • Patent number: 9138409
    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: 8629094
    Abstract: A method and composition for deodorizing soft surfaces such as carpeting and upholstery are disclosed. The method includes the spraying of a liquid composition on a soft surface and allowing the composition to absorb into the soft surface, form liquid agglomerations within the soft surface to the agglomerations can make contact with malodorants disposed within the soft surface. The composition is capable of penetrating rapidly and deeply into the soft surfaces for contacting odor-causing substances embedded therein. The composition comprises an active ingredient such as a glycol or triethanolamine. Other ingredients that contribute to the surface penetration and/or agglomeration formation include ethanol, water, fragrance and a combination of at least one nonionic and at least one ionic surfactant.

  • Patent number: 8440171
    Abstract: An air treating composition for eliminating odors from air in combination with specific spray valve and actuator requirements and spray performance parameters providing maximum dispersion of the active component in the composition into the air is disclosed. The particles of the composition are small so that the active component is dispersed into air as a fine dispersion to provide more contact with odors and to provide quick absorption of odors. The particle size of the composition is controlled through the selection of valve and actuator dimensions. The air treating and odor eliminating composition of the invention includes water, a low molecular weight polyol, an emulsifier, and a propellant. The composition may also include additional adjuvants such as solvent(s), fragrance(s), corrosion inhibitor, pH adjustor and the like.
