Useful:

• Chemical Classes: Solvents -> Glycol Ethers (E Series)
• Canonical SMILES: COCCO
• Inhalation Risk: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C.
• Effects of Short Term Exposure: The substance is mildly irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system, blood, bone marrow, kidneys and liver. Exposure at high levels could cause unconsciousness. Medical observation is indicated.
• Effects of Long Term Exposure: The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the blood and bone marrow. This may result in anaemia and lesions of blood cells. May cause toxicity to human reproduction or development.
• Description: Methoxyethanol is a glycol ether that has been known since the 1920s, but its use significantly increased in the 1970s. Cellosolve was a solvent product containing glycol ethers and registered in the 1920s by Carbide and Carbon Chemicals Corp. Glycol ethers are derived from either ethylene oxide (E-series) or propylene oxide (p-series) combined with an alcohol. Methoxyethanol is an E-series glycol ether derived from methanol and ethylene oxide. Other commonly used glycol ethers include ethoxyethanol, butoxyethanol, and methoxypropanol. Use of methoxyethanol has declined in recent years due to risk management procedures and replacement by other substances.
• Physical properties: Colorless liquid with a mild, ether-like odor. Experimentally determined detection and recognition odor threshold concentrations were <300 μg/m3 (<96 ppbv) and 700 μg/m3 (220 ppbv), respectively (Hellman and Small, 1974).
• Uses: 2-Methoxyethanol is considered a non-comedogenic raw material. It is used as a solvent in nail products and as a stabilizer in cosmetic emulsions. It is able to penetrate the skin and may cause skin irritation. The primary use of 2-methoxyethanol is as asolvent for cellulose acetate, certain syntheticand natural resins, and dyes. Other applications are in jet fuel deicing, sealing moisture-proof cellophane, dyeing leather, and use innail polishes, varnishes, and enamels. Solvent for low-viscosity cellulose acetate, natural resins, some synthetic resins and some alcohol-soluble dyes; in dyeing leather, sealing moistureproof cellophane; in nail polishes, quick-drying varnishes and enamels, wood stains.
