  • Toxicity Summary: IDENTIFICATION AND USE: In the literature 1-methoxy-2-propanol is often referred to as propylene glycol monomethyl ether (PGME). Commercial PGME (CAS 130-67-8) typically contains at least 98.5% 1-methoxy-2-propanol (alpha isomer) and only 1.5% of 2-methoxy-1-propanol (beta isomer). PGME is a colorless liquid, miscible with water and many organic solvents. This makes it useful for a wide variety of solvent applications in the manufacture of lacquers, paints, dyes, inks, cleaning agents and liquid soaps. HUMAN EXPOSURE AND TOXICITY: PGME alpha (1-methoxy-2-propanol) has low toxicity. In male volunteers, following exposure to 100 ppm of PGME the subjects felt that the odor was too strong to be tolerated, but odor tolerance developed within 25 min. During a 3.5-hr exposure at 100 ppm, mild eye irritation was noted in 3 of the 6 individuals. At 250 ppm, the majority of the 23 subjects exposed for 1-7 hr complained of eye, nose or throat irritation; several subjects developed headaches, and one was nauseated. None of the exposures resulted in changes in visual, coordination, neurological or brake-reaction tests. Clinical studies (e.g., blood cell count, SGOT, SGPT, BUN and complete urina Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for 1-methoxy-2-hydroxypropane(SRC), using an estimated log Kow of -0.49(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that 1-methoxy-2-hydroxypropane is expected to have very high mobility in soil(SRC). Volatilization of 1-methoxy-2-hydroxypropane from moist soil surfaces is not expected to be an important fate process(SRC) given a Henry's Law constant of 9.2X10-7 atm-cu m/mole(3). 1-Methoxy-2-hydroxypropane is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 12.5 mm Hg at 25 °C(4). Aerobic degradation using a sandy loam soil resulted in half-lives of <1 and <7 days at 0.2 and 100 ppm, respectively(5), indicating that biodegradation may be an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that 1-methoxy-2-hydroxypropane is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon a Henry's Law constant of 9.2X10-7 atm-cu m/mole(4). 1-Methoxy-2-hydroxypropane is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(5), an estimated BCF of 3(SRC), from an estimated log Kow of -0.49(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 90% of theoretical BOD using activated sludge in the Japanese MITI test(6) suggests that biodegradation is an important environmental fate process in water(SRC). 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), 1-methoxy-2-hydroxypropane, which has a vapor pressure of 12.5 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-methoxy-2-hydroxypropane 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 21 hours(SRC), calculated from its rate constant of 1.86X10-11 cu cm/molecule-sec at 25 °C(3). 1-Methoxy-2-hydroxypropane does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

Being a moderately volatile solvent, it improves paint penetration, flow properties, and the gloss of paint coats; it also prevents blushing and formation of fish eyes and blisters.

Questions this page answers

This substance is not unrestricted: cosmetic use is subject to the conditions in the cited official record. Check product type, body area, concentration, purity and warning requirements before deciding whether a formulation is compliant.

If this row does not reproduce conditions, open the cited official detail because omission does not mean unrestricted use. The Hotlist is an administrative compliance tool, not an exhaustive safety approval list.

The record cites Hotlist restricted entry 53, source version Health Canada Hotlist 2025-08-13. 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.
