General Description

Dimethyl Isosorbide (DMI) is a clear, colorless liquid derived from isosorbide, which itself is a sugar-based compound usually obtained from glucose or sorbitol. DMI is a high-purity, water-miscible solvent known for its low toxicity, excellent stability, and ability to enhance the delivery of active ingredients through the skin. Chemically, it is a dimethyl ether derivative of isosorbide.

Uses in the Cosmetic Industry

Dimethyl Isosorbide is widely used in personal care and cosmetic formulations due to its solvent, carrier, and penetration-enhancing properties.

Hazards and Safety

Dimethyl Isosorbide is considered low hazard, but still requires attention in formulation and handling:

Irritation Potential:Generally well-tolerated, though may cause mild skin or eye irritation in some individuals at high concentrations.
Toxicity:Low systemic toxicity. Not classified as a carcinogen, mutagen, or reproductive toxin.
Inhalation Risk:Minimal under normal use; not volatile at room temperature.
Safe Use Concentration:Typically used at 1–10% in cosmetic formulations.

CAS Number: 5306-85-4

INCI Name: Dimethyl Isosorbide

Composition: Pure compound — Dimethyl ether of isosorbide (a derivative of sorbitol)

Purity Grade: Cosmetic/Pharmaceutical Grade

Appearance: Clear, colorless liquid

Solubility: Miscible with water, alcohols, glycols, and many organic solvents.

Preservation: Generally does not require preservation (it is self-preserving due to low water activity); however, products containing Dimethyl Isosorbide may be preserved according to the full formulation needs.

Storage: Store in a tightly closed container, in a cool, dry, and well-ventilated area; protect from light and moisture

Raw Material Sources: Derived from sorbitol (which is plant-based, typically from corn or wheat) via chemical modification

Manufacture: Synthesized by methylation of isosorbide (itself obtained by dehydration of sorbitol)

Animal Testing: May vary by supplier; confirm with specific manufacturer (many modern suppliers are cruelty-free)

GMO: Non-GMO (when sourced from non-GMO plant materials)
