International Chemical Safety Cards 2-HYDROXYETHYL METHACRYLATE ICSC: 1724 Ethylene glycol monomethacrylate 2-Propenoic acid, 2-methyl-,2-hydroxiethyl ester HEMA C6H10O3 Molecular mass: 130.1 ICSC #    1724 CAS #     868-77-9 RTECS # OZ4725000 EC #         607-124-00-X November 13, 2008 Validated TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Water spray. Dry powder. Alcohol-resistant foam. EXPLOSION Above 97°C explosive vapour/air mixtures may be formed. Above 97°C use a closed system, ventilation. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Cough. Sore throat. Ventilation (not if powder), local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.  •EYES Redness. Safety spectacles and eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Sore throat. Aspiration hazard! Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: Chemical protection suit, filter respirator for organic gases and vapours. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Store only if stabilized. Keep in the dark. Cool. Ventilation along the floor.

International Chemical Safety Cards 2-HYDROXYETHYL METHACRYLATE ICSC: 1724 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance will polymerize due to heating, on contact with peroxides, and under the influence of light. Heating may cause violent combustion or explosion producing acrid smoke. The substance may also spontaneously polymerize if it is not stabilized. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: sensitization of skin (Sh); (DFG 2008). ROUTES OF EXPOSURE: INHALATION RISK: No indication can be given about the rate in which a harmful concentration of this substance in the air is reached. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes, the skin and the respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. See Notes. PHYSICAL PROPERTIES Boiling point: 250°C (calculated) (See Notes) Melting point: <-60°C Density: 1.07 g/cm³ Solubility in water, g/100 ml: (miscible) Vapour pressure, Pa at 25°C: 17 Relative vapour density (air = 1): 4.5 Flashpoint: 97°C c.c. Octanol/water partition coefficient as log Pow: 0.42 Viscosity, mm2/s at 20 °C: 8.4 ENVIRONMENTAL DATA N O T E S Boiling Point cannot be experimentally determined: at 1013 hPa polymerization occurs at elevated temperatures, other boiling point: 67 C at 4.6 hPa. Methacrylates are normally stabilized by addition of phenolic inhibitors during transport and storage. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. May cause cross sensitization towards other acrylates.
