Import Dimethyl Isosorbide — Buy in Bulk from Supplier in China

Dimethyl isosorbide (DMI) is a colorless, transparent liquid solvent with a minimum purity of 99.0% as specified in the listing. It is derived from sorbitol, a naturally occurring sugar alcohol, and exhibits low volatility, high thermal stability, and strong solvency for polar and nonpolar compounds. This makes it suitable for formulations where solvent consistency and low toxicity are critical, particularly in pharmaceutical and cosmetic manufacturing.

The compound typically contains less than 0.5% water and negligible levels of residual solvents such as methanol or acetone, consistent with industry standards for high-purity DMI. Its molecular structure allows it to act as a cosolvent that improves the dissolution of active pharmaceutical ingredients without compromising formulation stability. Typical grades in commercial use range from 98.5% to 99.5% purity, with the 99.0% minimum here aligning with the upper tier of standard industrial specifications.

Buyers in the pharmaceutical sector use this solvent for topical creams, transdermal patches, and injectable suspensions where solvent residue must be minimized. Cosmetic manufacturers apply it in serums and lotions to enhance skin penetration of actives like retinoids and peptides. Trade terms are flexible but require direct confirmation with the supplier regarding minimum order quantities, packaging options (typically 200kg HDPE drums), and shipping terms such as FOB or CIF. Delivery lead times are not specified and must be verified prior to order placement.
