Description

2-Methoxyethanol, or methyl cellosolve, is an organic compound with formula C 3H 8O 2 that is used mainly as a solvent. It is a clear, colorless liquid with an ether-like odor. It is in a class of solvents known as glycol ethers which are notable for their ability to dissolve a variety of different types of chemical compounds and for their miscibility with water and other solvents. It can be formed by the nucleophilic attack of methanol on protonated oxirane followed by proton transfer:
C 2H 5O+ + CH 3OH → C 3H 8O 2 + H+
2-Methoxyethanol is used as a solvent for many different purposes such as varnishes, dyes, and resins. It is also used as an additive in airplane deicing solutions. In organometallic chemistry it is commonly used for the synthesis of Vaska's complex and related compounds such as carbonylchlorohydridotris(triphenylphosphine)ruthenium (II). During these reactions the alcohol acts as a source of hydride and carbon monoxide.
2-Methoxyethanol is toxic to the bone marrow and testicles. Workers exposed to high levels are at risk for granulocytopenia, macrocytic anemia, oligospermia, and azoospermia.
The methoxyethanol is converted by alcohol dehydrogenase into methoxyacetic acid which is the substance which causes the harmful effects. Both ethanol and acetate have a protecting effect. The methoxyacetate can enter the Krebs cycle where it forms methoxycitrate.

Excerpt from ERG Guide 127 [Flammable Liquids (Water-Miscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)

8.Exposure controls/personal protection

8.1 Control parameters

Occupational Exposure limit values

NIOSH recommends that 2-methoxyethanol (2ME) ... be regarded in the workplace as having the potential to cause adverse reproductive effects in male and female workers. These recommendations are based on the results of several recent studies that have demonstrated dose related embryotoxicity and other reproductive effects in several species of animals exposed by different routes of administration. Appropriate controls should be instituted to minimize worker exposure to 2ME. NIOSH suggests that producers, distributors, and users of 2ME give this information to their workers and customers and that trade associations, and unions inform their members.

Recommended Exposure Limit: 10 Hour Time-Weighted Average: 0.1 ppm (0.3 mg/cu m), skin.

Biological limit values

no data available

8.2 Appropriate engineering controls

Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

8.3 Individual protection measures, such as personal protective equipment (PPE)

Eye/face protection

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

12.2 Persistence and degradability

AEROBIC: Biodegradation of 2-methoxyethanol (100-1000 mg/L) with activated sludge at 20 degrees C for 10 days resulted in 64.7% theoretical BOD(1). Biodegradation of 2-methoxyethanol at 3, 7, and 10 mg/L with filtered sewage seed in fresh water resulted in 30% theoretical BOD in 5 days and 88% theoretical BOD in 20 days; in salt water 6% theoretical BOD in 5 days and 39% theoretical BOD in 20 days was observed(2). Sewage seed degraded 2-methoxyethanol over 5 days resulting in 7% theoretical BOD using unadapted seed and 30% theoretical BOD using adapted seed(3). 2-Methoxyethanol, present at 100 mg/L, reached 83-94% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese Ministry of Trade and Industry (MITI) test(4).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for 2-methyoxyethanol(SRC), using a log Kow of -0.77(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(SRC).

12.4 Mobility in soil

The Koc of 2-methoxyethanol is estimated as 1(SRC), using a log Kow of -0.77(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-methoxyethanol is expected to have very high mobility in soil(SRC).
