Embodiment 1

[0081] A standard 0.78 fl oz aluminum aerosol container with a total volume of 33 ml was added at 8.5% by weight of a fragrance selected from the previously described group. The container was then sealed with a standard continuous valve and charged with 91.5% by weight butane 70 propellant.

Embodiment 2

[0083] A standard 0.78 fl oz aluminum aerosol container with a total volume of 33 ml was added at 5.2% by weight of a fragrance selected from the previously described group. The container was then sealed with a standard continuous valve and charged with 94.8% by weight HFC-152a propellant.

[0084] In each case, the resulting container was then filled into a solenoid operated metered dose aerosol spray device such as in the applicant's co-pending patent applications GB 0427646.5, GB 0503098.6, GB 0503042.4, GB 0503095.2 , GB 0521064.6, GB 0521061.2, GB 0521063.8 and GB 0521071.1 are hereby incorporated by reference.

[0085] The resulting device has excellent performance throughout the lifetime of the container, as evidenced by the absence of "dripping".

Abstract

A method of dispensing periodic metered doses of a single phase aerosol composition wherein: the aerosol composition comprises a propellant and at least one active component selected from the group comprising fragrances, perfumes, air fresheners, deodorants and sanitisers; the metered dose spray rate is between 0.1 and 2 g / s of aerosol composition; and the mean particle size of each dose of the aerosol composition is between 1 mum and 40 mum.

Description

technical field [0001] The present invention describes a method of dispensing a single phase aerosol composition by use of a metered dose device, a composition for use in said device, said composition and a method of manufacture of a device containing said composition. Background technique [0002] Aerosol is a common industry term used to refer to a number of products that can be dispensed as a mist, stream, spray, powder or even foam. Pressurized cans are the typical vehicle used to form aerosols for dispensing personal, household, industrial and pharmaceutical products, providing an inexpensive and easy-to-use method of dispensing such products. Typically, an aerosol dispenser includes a container that holds a liquid product for dispensing, such as soap, insecticide, paint, deodorant, sanitizer, or air freshener, among others. A pressurized propellant is used to provide sufficient force to expel the liquid product from the container. The user thus actuates the aerosol d...
