BUTYL, DECYL, CETYL, EICOSYL METHACRYLATE

Diamond	Hazard	Value	Description
2 1 2	Health	1	Can cause significant irritation.
	Flammability	2	Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
	Instability	2	Readily undergoes violent chemical changes at elevated temperatures and pressures.
	Special

A colorless liquid with a mild odor. Less dense than water and insoluble in water. Hence floats on water. (USCG, 1999)

• Highly Flammable
• Polymerizable

Insoluble in water.

Behavior in Fire: Containers may explode. (USCG, 1999)

Inhalation may cause nausea because of offensive odor. Contact with liquid causes irritation of skin. Ingestion causes irritation of mouth and stomach. (USCG, 1999)

BUTYL, DECYL, CETYL, EICOSYL METHACRYLATE is a mixture of four esters of methacrylic acid. Reacts 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 with basic (caustic) solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Polymerization may occur when heated, exposed to light or mixed with peroxides. Polymerization can generate large quantities of heat. (USCG, 1999).

• Acrylates and Acrylic Acids
• Polymerizable Compounds

• Cellulose-Based Absorbents
• Mineral-Based & Clay-Based Absorbents
• Dirt/Earth

Excerpt from 130 [Flammable Liquids (Water-Immiscible / Noxious); polymerization hazard]:

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 car or tank truck 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, 2020)

Fire Extinguishing Agents Not to Be Used: Water may be ineffective.

Fire Extinguishing Agents: Dry chemical, foam, carbon dioxide (USCG, 1999)

Excerpt from 130 [Flammable Liquids (Water-Immiscible / Noxious); polymerization hazard]:

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, 2020)

Self-contained respirator; impervious gloves; chemical splash goggles (USCG, 1999)

No information available.

INHALATION: Remove to fresh air, give oxygen or artificial respiration as required.

EYES: Flush with copious amounts of water for 15 min. and consult physician.

SKIN: Wash with soap and water.

INGESTION: Induce vomiting; call a physician. (USCG, 1999)
