Abstract
Chemical compositions are provided, for use as topical anesthetics or skin refrigerants. These compositions do not cause the depletion of the stratospheric ozone layer and are non-toxic, non-carcinogenic and less flammable than ethyl chloride. Also these chemical compositions match the skin temperature versus time profile needed in the management of myofascial pain syndromes, for effectively freezing skin prior to minor skin surgery and for effectively freezing skin prior to giving painless injections.
