  • Health Effects: The principal acute effect of inhalation exposure to BCEE vapor is irritation and injury to the cells of the respiratory epithelium.

  • Toxicity Summary: BCEE is extremely meabolized, with thiodiglycolic acid (TDGA) being the principal endproduct. The pathway leading to TDGA formation is uncertain, but probably involves oxidative cleavage of the ether bond to yield chloroacetaldehyde and 2-chloroethanol.

  • Environmental Bioconcentration: A BCF of 0.4 to 1.3 in carp(1) and a BCF of 11 in bluegills exposed to bis(2-chloroethyl) ether for 14 days(2) was observed. According to a classification scheme(3), these BCF values suggest that 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 120(SRC), determined from a log Kow of 1.29(2) and a regression-derived equation(3), indicates that bis(2-chloroethyl) ether is expected to have high mobility in soil(SRC). Volatilization of bis(2-chloroethyl) ether from moist soil surfaces is expected to be important(SRC) given an estimated Henry's Law constant of 2.9X10-5 atm-cu m/mole(SRC), calculated from its vapor pressure(4) and water solubility(5). In a 140 cm long column containing Lincoln fine sand collected in Ada, OK, 86% of the applied bis(2-chloroethyl) ether reached 140 cm, indicating minimal adsorption to this soil(6). The potential for volatilization of bis(2-chloroethyl) ether from dry soil surfaces may exist(SRC) based on a vapor pressure of 1.55 mm Hg(4). No data concerning the hydrolysis of bis(2-chloroethyl) ether in soil were available. The hydrolysis rate constant for bis(2-chloroethyl) ether in water was determined to be 2.6X10-5/hour under neutral conditions; this corresponds to a half-life at pH 7 and 25 °C of 3 years(7). Bis(2-chloroethyl) ether may be resistant to biodegradation under aerobic conditions in environmental medi Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a log Kow of 1.29(2) and a regression-derived equation(3), indicates that bis(2-chloroethyl) ether is not expected to adsorb to suspended solids and sediment in water(SRC). Bis(2-chloroethyl) ether is expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 2.9X10-5 atm-cu m/mole(SRC), calculated from its vapor pressure(4) and water solubility(5). Estimated volatilization half-lives for a model river and model lake are 40 hours and 16 days, respectively(3,SRC). According to a classification scheme(6), a BCF of 0.4 to 1.3(7) suggests the potential for bioconcentration in aquatic organisms is low(SRC). In one study, bis(2-chloroethyl) ether showed 50% biodegradation after 30 days when incubated with Ohio River water; acclimation appears to be important(8). Bis(2-chloroethyl) ether may be resistant to biodegradation under aerobic conditions in environmental media based upon screening test data from studies using activated sludge(7,SRC). In general, many ethers are known to be resistant to biodegradation(9). The hydrolysis rate constant for bis(2 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), bis(2-chloroethyl) ether, which has a vapor pressure of 1.55 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase bis(2-chloroethyl) ether 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 5 days(3,SRC). Direct photolysis in the atmosphere is not expected to be a major significant degradation process since no functional groups are present in bis(2-chloroethyl) ether that would lead to absorption of sunlight(SRC).

Questions this page answers

This official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. Regional annex coverage does not replace member-state implementation dates, notifications or national deviations.

The record cites ASEAN Annex II, reference 1174, source version 2026-1. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.
