Definitions

• the present invention relates to a sprayable bleaching composition packaged in a container adapted to produce a spray.
• the present invention is primarily but not exclusively applicable to the treatment of hard surfaces.
• Halogen bleaches in particular hypochlorite, are known to be some of the most effective hygiene agents, especially at low concentrations, and are available in commercial quantities at acceptable cost. Halogen bleaches provide a hygiene benefit against a wide range of microbes including bacteria, moulds, yeast and fungi.
• Cleaning compositions have traditionally been delivered to surfaces by use of a carrier such as a cloth or sponge onto which the composition is poured or which is dipped into a solution of the composition. This mode of application results in some wastage of the product due to absorbtion onto the cloth or sponge.
• liquid products have been provided in a package adapted to produce a fine spray (aerosol) or jet of the product to facilitate delivery to a surface.
• Typical spray heads comprise a single, relatively small, aperture to which product is fed by pump means operated by a trigger mechanism.
• the deciding factors in determining whether a particular spray head will produce a mist or a jet include product properties, spray aperture geometry and spray pressure.
• J62/28600 proposes the use of specific solvents
• WO94/24259 proposes the use of surfactants in combination with a specific design of the spray head of the package
• EP 594 314 proposes the control viscosity by means of a selected surfactant in order to reduce the bleach odor, including in cases when airbone droplets are created while dispensing.
