Description

Spray bleach compositions with reduced irritation to the respiratory system

Halogen bleach, specifically hypochlorite, is known as one of the most effective hygienic preparations, especially at low concentrations, and is available in commercial quantities at acceptable costs. Halogen bleaching provides hygienic benefits against a wide range of microorganisms, including bacteria, fungi, yeasts and fungi.

Cleaning compositions have traditionally been applied onto the surface using media such as cloths or sponges on which the composition is poured or wetted in a solution of the composition. This application form wastes part of the product because the product is absorbed onto a cloth or sponge.

More recently, liquid products have been provided in packages suitable for producing fine sprays (aerosols) or jets of products to facilitate delivery to surfaces. Conventional spray heads comprise simple, relatively small perforations in which the product is supplied by pump means actuated by a trigger mechanism. Determinants that determine whether a particular spray head produces a mist or jet include product characteristics, spray puncture type, and spray pressure.

A known problem with sprays is that airborne droplets are formed that directly irritate the user's respiratory system as a direct result of spraying fine mist, or by the impact of jets on hard surfaces. As a result, in particular, according to the instructions for the use of certain products containing relatively high concentrations of halogen bleach, the user is advised to spray onto the cloth for subsequent application onto the surface without spraying the product directly onto the surface. . Using a cloth or sponge in this way reduces the convenience of using a spray.

It is therefore an object of the present invention to provide a sprayable composition comprising a halogen bleach which does not present the above mentioned problems of irritating the respiratory system of the user due to the inhalation of the solvent droplets.

Various solutions to this problem have been proposed in the art. For example, J62 / 28600 suggests the use of certain solvents; WO 94/24259 proposes the use of surfactants in combination with specially designed spray heads of packages; EP 594 314 proposes a viscosity control by using a surfactant selected to reduce bleach odors, including when air droplets are produced upon spraying. Finally, WO95 / 07957 proposes the use of concentrators to control the size of the irritant particles generated due to the use of nebulizers.

The inventors have now found that this object can be met by combining a halogenated bleach and a sprayable liquid composition further comprising an effective amount of an organic or inorganic derived -NH ₂ compound. While not wishing to be bound by theory, it is believed that the induced -NH ₂ compound does not prevent the formation or inhalation of the flux droplets but reduces or eliminates the stimulus resulting therefrom.

Compositions comprising a halogen bleach and an inorganic derived -NH ₂ compound have already been described in the art, but not for spray compositions, for example, Japanese Patent Application Laid-Open No. 63-108099, European Patent No. 119 560 See Belgian Patent No. 749 728, US Patent No. 2,438,781, US Patent No. 3,749,672, UK Patent No. 2,078,522, European Patent No. 362 178, US Patent No. 3,749,672.
