Aerosol Freeze Formulation and Delivery System

Abstract

An environmentally safer aerosol freeze spray formulation and delivery system that is under pressure in an aerosol can and can only be released by pulling the trigger of the trigger sprayer by a finger or fingers. The trigger sprayer unit cannot be sprayed until the tab is pulled. The can is cylindrical canister housing and has a dip tube that goes into the can into the freeze spray. The freeze spray formulation in the can travels up through the dip tube up to the trigger sprayer and out a nozzle in which is cold and will flow out as an mist when the trigger is depressed.
