How cold is Ethyl Chloride spray?
The temperature of the product will vary due to the delivery system (fine stream, medium stream or mist spray) and the distance from which the product is sprayed (see Question 5). Since Gebauers skin refrigerants work by evaporation, the faster a product evaporates from the surface of the skin, the colder the cooling effect will be. Stream sprays dispense a larger volume of product at a specific pinpoint site, so it takes longer for the product to evaporate. The stream products range from around -4C at 2 inches to -8C at 7 inches. The fine stream spray can be used from18 inches and reaches a temperature of approximately -20C. Although the stream spray produces an effective cooling of the skin, it is not as cold as the mist but the cooling effect lasts longer than the mist due to the lowered evaporation rate of the chemical from the point of contact. The mist spray reaches a temperature of approximately -15C at 3 inches. Mist streams produce very fine droplets of product that are disper
