Methoxy propanol, also known as propylene glycol methyl ether, is a clear, colourless liquid with a faint ether-like odour. It is soluble in water and has moderate volatility. Methoxy propanol is a propylene oxide-based glycol ether which is fast evaporating and hydrophilic. It has low surface tension as well as excellent solvency and coupling abilities.
Methoxy propanolis produced by reacting propylene oxide with methanol using a catalyst.
Synonyms: CAS No. 107-98-2, Propylene glycol monomethyl ether, 1-Methoxy-2-propanol, 1-Methoxy-2-hydroxypropane, 1-Methoxypropan-2-ol, 1-Methoxypropanol-2, 2-Methoxy-1-methylethanol, 2-Propanol-1-methoxy
Applications of Methoxy propanol (Propylene glycol methyl ether)
Methoxy propanol isprimarily used as a chemical building block for the production of propylene glycol methyl ether acetate. It is also used as a solvent in manufacturing processes for the chemical, automotive and agricultural industries and in paint, lacquer and varnishes. It is used as a coalescing agent in water-based paints and inks where it promotes polymer fusion during the drying process.
Methoxy propanol is formulated into a wide range of cleaners for industrial and commercial use such as those for ovens, glass, hard surfaces, floors, carpets and upholstery, as well as in speciality sanitation products such as swimming pool cleaners. It is also present in many everyday products such as polish, laundry aids, caulk, sealants, pesticides, inks for ballpoint and felt-tip pens, synthetic resin and rubber adhesives.
Storage and Handling
Methoxy propanol and its vapours are flammable. It should be stored in a cool, well-ventilated place away from sources of ignition. It must be isolated from incompatible materials such as strong oxidizers, bases and acids.
Methoxy propanol is a mild, but usually temporary, irritant to the eyes. Repeated or prolonged contact with the skin may cause irritation, and in very large amounts skin absorption may cause drowsiness or dizziness. High levels of methoxy propanol vapour may produce eye, nose and throat irritation, and at very high levels may produce anaesthetic or narcotic effects. Unnecessary exposure should be prevented by appropriate work practices and engineering controls, adequate ventilation and by the use of approved personal protective equipment including gloves, clothing and safety goggles and the use of respirators where appropriate to the task being carried out.
