Epichlorohydrin

Epichlorohydrin (abbreviated ECH) is an organochlorine compound and an epoxide. It is a colorless liquid with a pungent, garlic-like odor, moderately soluble in water, but miscible with most polar organic solvents. Epichlorohydrin is a highly reactive compound and is used in the production of glycerol, plastics, epoxy glues and resins, and elastomers. In contact with water, epichlorohydrin hydrolyzes to 3-MCPD, a carcinogen found in food.
Epichlorohydrin (EPI) is an extremely versatile chemical intermediate used in a wide variety of applications. Approximately 76% of the world’s consumption of (EPI) is used to make epoxy resins.
EPI is flammable. Direct, prolonged contact with pure EPI as liquid can severely damage the skin and eyes. Vapors may also produce eye irritation and damage to cornea of the eye. EPI is a probable carcinogen, a poison that can cause death at higher exposures, a mutagen and a skin sensitizer. 
Occupational exposures are possible; however, consumer exposures are not likely because end-use products are expected to contain only trace levels of EPI. Industrial operations use EPI in closed systems and are designed with engineering controls to minimize personnel and environmental exposures.
EPI is considered a hazardous chemical. If released into the environment, however, it biodegrades rapidly.
