1-Methoxy-2-propanol
Description
1-Methoxy-2-propanol (CAS 107-98-2), commonly known as PGME or Propylene Glycol Methyl Ether, is a slow-evaporating glycol ether solvent used across coatings, adhesives, and personal care formulations.
Its controlled evaporation rate and broad solvency make it a preferred choice where film formation, flow, and compatibility with diverse resin systems are critical procurement considerations for manufacturers.
In architectural and industrial coatings, PGME improves flow and leveling in waterborne and solvent-based systems, reducing surface defects in the final film. This ensures a high-quality finish for industrial applications.
Adhesive and sealant manufacturers use it to dissolve or dilute resin components, ensuring consistent viscosity and open time in formulations. In printing inks, it supports pigment dispersion and controls drying speed.
Personal care formulators incorporate it as a solvent and carrier in products such as hair sprays, skin toners, and nail treatments where low odor and skin compatibility are required for consumer safety.
1-Methoxy-2-propanol is supplied as a clear liquid in drum, IBC, and bulk quantities. Standard commercial grades include technical and industrial-grade material, with high-purity grades available for cosmetic use.
Buyers should confirm purity specifications and isomer content, particularly the ratio relative to 2-methoxy-1-propanol, when sourcing for sensitive formulation work to ensure consistent performance and safety.
