CLORETILO CHEMIROSA is a local anesthetic "a frigore', whose effect is achieved by cooling the irritated area, being able to reach a temperature of up to ‑20°. This cooling is produced by the rapid evaporation of the­ ethyl chloride, which produces ischemia in the tissues of the skin's surface with the consequential loss of sensitivity in the nerve endings.


Anesthesia is achieved in 15 to 20 seconds, which is displayed by the white, hardened appearance of the skin.


Local anesthetic for treatment prior to minor surgical operations and in sports medicine.
