Description
2-Methyl-1,3-propanediol (CAS 2163-42-0) is a short-chain diol commercially known under the trade name MPDIOL and also referred to as MP diol glycol or Polyol 4. It carries no assigned E-code and is registered under EC 606-809-0. The molecular formula is C4H10O2.
In polyester and polyurethane production, its branched structure introduces controlled chain irregularity, lowering crystallinity and improving flexibility in coatings and adhesives. In personal care formulations, it functions as a humectant and solvent carrier, drawing moisture to the skin while solubilising active ingredients and fragrances at low concentrations.
MPDIOL is supplied as a liquid and is subject to REACH registration requirements for European market supply. It is handled under HS code 2905.39.9000 for import and export classification. Procurement teams should confirm grade specifications and available pack sizes directly with the supplier to ensure compliance with application-specific standards.
