Description
Diethylene Glycol Monomethyl Ether (CAS 111-77-3), commercially known as Methyl Carbitol, Dowanol DM, and Poly-Solv DM, is a glycol ether solvent with the molecular formula C5H12O3. It carries no assigned E-code and is registered under EC number 203-906-6.
In coatings and printing inks, it functions as a coalescing solvent and viscosity modifier, improving film formation by slowing evaporation and maintaining resin solubility during application. In personal care formulations, it acts as a humectant and solubiliser, retaining moisture and enabling uniform dispersion of active ingredients across aqueous and semi-aqueous systems.
The material is supplied as a liquid under REACH compliance and is available in standard industrial drum and IBC packaging. Procurement teams should confirm grade specifications against application requirements, particularly for cosmetic or adhesive end uses where purity thresholds and supplier safety data sheet documentation are required.
