Spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray head have been known to cause respiratory distress in the form of a choking mist. The choking mist associated with aerosol use can be reduced or eliminated by formulating surface cleaning compositions that can be dispensed through a spray head resulting in an aerosol or mist droplet having a median particle size greater than about 170 mu m, more preferably 200 mu m. We have found that typical spray-on cleaners have a median particle size less than about 170 mu m and, depending on the concentration and degree of irritation of strong base or strong acid components can cause severe respiratory distress. Preferred thickeners have been found for use in the non-choking aerosol or mist compositions. |
