Odorless Mineral Spirits

  • Aliphatic solvents
  • CAS 64741-65-7

Odorless Mineral Spirits (CAS 64741-65-7) appears in 4 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.

Low acute toxicity in normal use. Repeated or prolonged skin contact can cause dermatitis. Vapors at high concentrations cause CNS depression — ventilate when using indoors. The 'odorless' designation refers to aromatic removal, not absence of all volatiles.

Odorless mineral spirits (OMS) is a highly refined aliphatic petroleum distillate with aromatic content reduced to <1%. It is the standard carrier solvent in paste and liquid waxes, dissolving carnauba and synthetic wax polymers for easy application and release.

The low aromatic content substantially reduces health risk vs. standard mineral spirits: no benzene, toluene, or xylene. The primary concern is dermal exposure over time (irritant contact dermatitis) and inhalation of vapors in poorly ventilated spaces.

From an environmental standpoint, OMS is a slow-degrading petroleum fraction. The tiny quantities in consumer wax products are not an aquatic concern at normal dilution, but large spills to soil or water should be contained.
