General Description
Colorless liquid. Less dense than water and insoluble in water. A mixture of esters of methacrylic acid. (USCG, 1999)
Hazards
Reactivity Alerts
Air & Water Reactions
Insoluble in water.
Fire Hazard
Behavior in Fire: Heat can induce polymerization with rapid release of energy. Sealed contawiners may rupture explosively. (USCG, 1999)
Health Hazard
Inhalation temporarily reduces blood pressure from 5 to 25%, increases respiratory rate, decreases heart rate, and causes some EKG changes. Liquid may cause irritation of eyes and skin. May be harmful if swallowed. (USCG, 1999)
Reactivity Profile
DODECYL/PENTADECYL METHACRYLATE 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 interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Tends to polymerize. Oxidizing and reducing agents may initiate polymerization. Polymerization may also occur when heated (USCG, 1999).

First Aid
INHALATION: Move victim to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.
EYES OR SKIN: Flush with running water for at least 15 minutes; hold eyelids open if necessary. Wash skin with soap and water.
INGESTION: If victim is conscious, have victim drink water or milk and induce vomiting. If victim is unconscious or having convulsions, do nothing except keep victim warm. (USCG, 1999)
