  • Toxicity Summary: IDENTIFICATION: Epichlorohydrin is a colorless liquid in which the vapor forms explosive mixtures in air. Phosgene, hydrogen chloride and carbon monoxide are liberated while burning. Acids, caustic solutions and halide salts initiate polymerization reactions. The compound is very reactive with metals such as zinc, aluminum, anhydrous metal halides, strong acids and bases along with alcohol containing materials. In the presence of moisture epichlorohydrin is corrosive to steel. Epichlorohydrin has a chloroform like odor. It is soluble in water. Epichlorohydrin is used for the manufacture of glycerine and unmodified epoxyresins. It is also used in the production of elastomers, glycidil ether, cross linked food starch, wet strength resins for the paper industry, water treatment resins, surfactants, ion exchange resins, plasticizers, dyestuffs, pharmaceutical products, emulsifiers, lubricants and adhesives. HUMAN EXPOSURE: On the basis of use patterns and the chemical and physical properties of epichlorohydrin, human exposure is mainly occupational, through vapor inhalation, direct skin contact and a slight exposure resulting from food consumption. Five human volunteers showed signific Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated for epichlorohydrin(SRC), using a log Kow of 0.45(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 40(SRC), determined from a log Kow of 0.45(2) and a regression-derived equation(3), indicates that epichlorohydrin is expected to have very high mobility in soil(SRC). Volatilization of epichlorohydrin from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.0X10-5 atm-cu m/mole(SRC), calculated from a vapor pressure of 16.4 mm Hg(4) and water solubility of 65,900 mg/L(5). The potential for volatilization of epichlorohydrin from dry soil surfaces may exist based upon the vapor pressure(4). Epichlorohydrin may undergo hydrolysis in moist soil surfaces based on a hydrolysis half-life of 8.2 days in distilled water(6). Epichlorohydrin achieved 3% of the theoretical BOD in a sewage sludge over a 5 day incubation period, but achieved 14% of the theoretical BOD following acclimation(7), suggesting that biodegradation in acclimated soils may be important(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 40(SRC), determined from a log Kow of 0.45(2) and a regression-derived equation(3), indicates that epichlorohydrin is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.0X10-5 atm-cu m/mole(SRC), calculated from its vapor pressure of 16.4 mm Hg(4) and water solubility of 65,900 mg/L(5). Using this estimated Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 19 hours and 12 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low. The hydrolysis half-life of epichlorohydrin is 8.2 days in distilled water and 5.3 days in simulated seawater(8). Epichlorohydrin achieved 3% of the theoretical BOD in a sewage sludge over a 5 day incubation period, but achieved 14% of the theoretical BOD following acclimation(9); thus biodegradation in acclimated water may be important(S Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), epichlorohydrin, which has a vapor pressure of 16.4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase epichlorohydrin is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 36 days(SRC), calculated from its rate constant of 4.4X10-13 cu cm/molecule-sec at 25 °C(3).

Synthetic glycerine is an ECH 'sink' allowing integrated players to use spare capacity to run synthetic glycerine plants independently of the natural glycerine market, and exit or substitute the natural product whenever epoxy demand requires.
