What Is Dimethyl Sulfoxide
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2S=O. This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high boiling point of 189 degrees, a melting point of 18.5 degrees and a flash point of 95 degrees closed cup.
Use in the Pharmaceutical Industry
Due to its excellent permeability and biocompatibility, DMSO is widely used as a drug delivery vehicle in the pharmaceutical sector, demonstrating particularly significant efficacy in treating conditions requiring high permeability, such as tumors and psoriasis. Its ability to penetrate biological membranes makes it a carrier for topical drug delivery, and it is used as a cryoprotectant in cell and tissue preservation.
Use in Cosmetics and Agriculture
DMSO's moisturizing properties secure its place in the cosmetics field, where it is commonly used in the manufacture of products like skin creams and shampoos. Owing to its strong solubility, DMSO is employed in the production of agricultural chemicals like pesticides and herbicides, where it serves as a solvent and carrier for the active ingredients.
Use as a Solvent and in Batteries
In chemical synthesis, DMSO serves as an efficient solvent and reaction medium, widely applied in synthesizing polymer materials, dyes, fragrances and more. In battery manufacturing, DMSO functions as an electrolyte solvent, contributing to enhanced battery performance. It also finds use in paints, coatings and inks, and as an additive in rubber and plastic formulations.
Quality and Specifications
DMSO is supplied in industrial grade with 99.0 percent minimum purity and in pharma or high-purity grade with 99.9 percent minimum. The product is stable under normal conditions and classified as low toxicity with irritation to skin and eyes.
