General Description
A colorless liquid. Flash point 136°F. Slightly less dense than water and insoluble in water. Vapors are much heavier than air and may be narcotic in high concentrations. May emit acrid smoke and irritating fumes when heated to high temperatures. Used as a solvent and in making rubber.
Hazards
Reactivity Alerts
none
Air & Water Reactions
Flammable. Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: Emits toxic fumes under fire conditions. Vapor may travel considerable distance to a source of ignition and flash back. (USCG, 1999)
Health Hazard
May be harmful by inhalation, ingestion, or skin absorption. Causes eye and skin irritation. (USCG, 1999)
Reactivity Profile
CYCLOHEXANOL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Belongs to the Following Reactive Group(s)
- Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Potentially Incompatible Absorbents

Response Recommendations
Isolation and Evacuation
Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).
FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
Firefighting
Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:
CAUTION: The majority of these products have a very low flash point. Use of water spray when fighting fire may be inefficient.
SMALL FIRE: Dry chemical, CO2, water spray or regular foam. If regular foam is ineffective or unavailable, use alcohol-resistant foam.
LARGE FIRE: Water spray, fog or regular foam. If regular foam is ineffective or unavailable, use alcohol-resistant foam. Avoid aiming straight or solid streams directly onto the product. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)
Non-Fire Response
Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material.
LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2024)
Protective Clothing
Self-contained breathing apparatus, rubber boots and heavy rubber gloves. (USCG, 1999)

First Aid
INHALATION: Call for medical aid. Remove the victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
EYES: Flush immediately with copious amounts of water for at least 15 minutes.
SKIN: Wash immediately with soap and water with copious amounts of water. (USCG, 1999)
