Specification

1.General Description :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.
2.Air & Water Reactions :Flammable. Soluble in water.
3.Reactivity Profile: Methylcyclohexanol is incompatible with the following: Strong oxidizers .
Health Hazard 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.
4.Fire Hazard: 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.
