Polymerizable

Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.

This chemical is probably combustible. (NTP, 1992)

|Warning|H317 (99.62%): May cause an allergic skin reaction [Warning Sensitization, Skin]|P261, P272, P280, P302+P352, P321, P333+P313, P363, and P501|Aggregated GHS information provided by 1593 companies from 6 notifications to the ECHA C&L Inventory.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: If you spill this chemical, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with alcohol followed by washing with a strong soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Drug Information

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

TESTED AT 4% IN PETROLATUM, IT PRODUCED NO IRRITATION AFTER A 48-HOUR CLOSED-PATCH TEST IN 25 HUMAN SUBJECTS. A MAXIMIZATION TEST WAS CARRIED OUT ON 25 VOLUNTEERS. THE MATERIAL WAS TESTED AT A CONCENTRATION OF 4% IN PETROLATUM AND PRODUCED NO SENSITIZATION REACTIONS.

Ethyl 3-phenylglycidate Use and Manufacturing

Methods of Manufacturing

It is derived from the reaction of benzaldehyde and ethyl chloroacetate in the presence of a basic polycondensation agent. Under the catalysis of silver salt, it is derived from the reaction of phenylglycidic acid and iodoethane.

Uses

GB 2760-1996 allows the use of edible spices. It is mainly used to formulate strawberry, cherry and other berry flavors.
