Cryogesic Fine Spray works as a vapo-coolant when sprayed topically onto the skin. It creates an analgesic effect, when sprayed onto the skin, and makes the skin cold and less sensitive as the liquid evaporates. This effect lasts for about 30-45 seconds, until the skin re-warms. Cryogesic Spray contains Ethyl Chloride and is a rapid-acting vapo-coolant spray, providing short term topical local analgesia for minor invasive procedures. Do not spray on open wounds. Do not over-cool skin as this may cause frostbite. Repeated exposure may cause skin dryness or cracks. In clinical use, minimise inhalation of vapours by the patient, especially when applying to head and/or neck. Do not spray into eyes. Use in a well-ventilated area. Solvent vapours can form explosive mixtures with air. Do not expose to temperatures exceeding 50°C. Do not spray on or near a naked flame or incandescent material
