Dimethyl Ether

What is Dimethyl Ether?

Dimethyl Ether, chemically C2H6O, is a synthetic, flammable gas produced from methanol or syngas processes. In cosmetics, it appears mainly in aerosol categories like hair sprays, deodorants, dry shampoos, and shaving foams. Pressurized into liquid form, it generates the force to release formulations as fine mists or foams, promoting uniform application without residue upon evaporation. As a solvent, it dissolves oils, fragrances, and actives efficiently across water- and oil-based systems. It also modifies viscosity, stabilizing textures, enhancing spreadability, and preventing separation for consistent performance during use.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Enables precise, even delivery in spray products for hassle-free application.

Dissolves diverse ingredients to create stable, homogeneous formulas.

Adjusts thickness to improve product feel and handling on skin or hair.
