Description
1-Methoxy-2-propanol (CAS 107-98-2), commonly known as propylene glycol monomethyl ether or PM glycol ether, is a glycol ether solvent sold under trade names including DOWANOL PM, ARCOSOLV PM, Closol, and Dowanol 33B. It carries no E-code designation and is classified under HS code 29094919.
In coatings and printing inks, it dissolves resins and controls evaporation rate to improve film leveling and reduce surface defects. In personal care formulations, it functions as a solvent carrier that enhances active ingredient penetration and acts as a preservation booster by disrupting microbial cell membranes at low concentrations.
This product is supplied as an industrial-grade liquid and is subject to REACH registration requirements within the EU. Procurement teams should confirm supplier SDS compliance and purity specifications prior to sourcing. Standard packaging formats typically include drums and IBC containers for bulk industrial supply.
