2-Methylcyclohexanol is a straw-colored liquid. Weak, menthol-like odor. The odor threshold is 490 ppm. (higher than the OEL).
Colorless viscous liquids with a menthol-like odor. Less dense than water. Flash point 136°F. Vapors heavier than air. May be toxic by ingestion. Used as a solvent and to make soaps and detergents.
Moderately toxic by ingestion and subcutaneous routes. Mildly toxic by skin contact. Human system effects by inhalation: antipsychotic, unspecified liver and kidney effects. Combustible when exposed to heat, flame, or oxidizers. On heating it emits acrid fumes; can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical.

Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Methylcyclohexanolmust be stored to avoid contact with strong oxidizers (suchas peroxides, chlorates, perchlorates, nitrates, and permanganates), since violent reactions occur. Sources of ignition,such as smoking and open flames, are prohibited wheremethylcyclohexanol is used, handled, or stored in a mannerthat could create a potential fire or explosion hazard.

Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Attacks some plastics, rubber, and coatings.
UN 2617 (METHYLCYCLOHEXANOLS, flammable)
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Drug Information
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
METHYLCYCLOHEXANOL Use and Manufacturing
Methylcyclohexanol is used as a blendingagent in textile soaps as an antioxidant inlubricants, and as a solvent for lacquers.
Solvent for lacquers; blending agent in textile soaps; antioxidant in lubricants
Solvent for cellulose esters and ethers and forlacquers, antioxidant for lubricants, blending agentfor special textile soaps and detergents.
Methylcyclohexanol is produced by hydrogenating m- and p-cresols. Methylcyclohexanol can exist as three separate isomers, ortho, meta, and para, or as a mixture of isomers. The commercial product consists essentially of the meta and para isomers. Methylcyclohexanol is used as a solvent in lacquers, a blending agent in textile soaps, and an antioxidant in lubricants. In addition, methylcyclohexanol dissolves gums, oils, resins, and waxes.
