Methylpropanediol
What is Methylpropanediol?
Methylpropanediol (CAS 2163-42-0), commonly abbreviated as MPD, is a diol solvent and humectant used in personal care, pharmaceutical, and polymer manufacturing.
Where is Methylpropanediol used?
- Personal care: humectant and solvent in skin creams, serums, and hair care products
- Pharmaceutical: carrier solvent in topical preparations where controlled penetration and stability are required
- Polymer chemistry: monomer or chain extender in polyesters, polyurethanes, and UV-curable resins
- Coatings and adhesives: reactive intermediate to tune film performance
- Its low viscosity and strong solvency make it a practical alternative to propylene glycol.
Good to know: Cosmetic-grade material meets purity requirements suitable for leave-on and rinse-off personal care applications. Pharmaceutical-grade supply is available from select manufacturers for use in regulated topical formulations.
Commercial specifications
- Clear, low-viscosity liquid in standard drum and IBC quantities
