About Odorless Mineral Spirits

Odorless mineral spirits (OMS), sometimes sold under the trade name Gamsol, are a hydrotreated petroleum distillate refined to strip out the aromatic hydrocarbons responsible for the sharp odor and higher toxicity of standard mineral spirits. The result is a mild-odor, slower-evaporating solvent that's gentler to work with indoors.

Because OMS is a mixture rather than a single compound, its exact boiling range and composition can vary slightly by refining batch — Superior Chemical Co. sources consistent, low-aromatic lots suited for professional and industrial use.

Frequently asked
Is OMS the same as mineral spirits?
OMS starts from the same petroleum distillate base as standard mineral spirits but goes through additional hydrotreating to remove most of the aromatic hydrocarbons, which is what gives it a much milder odor and lower toxicity profile.
What's the difference between OMS and Gamsol?
Gamsol is a well-known branded odorless mineral spirit product; 'OMS' is the generic category name. Functionally, they serve the same purpose and Superior Chemical Co. can source to match your specification.
What container sizes are available?
OMS ships in 55-gallon drums, 275-gallon totes, or 8,000-gallon tankers.
