PHENYL GLYCIDYL ETHER, an ether, can act as a base. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

Fires involving this compound can be controlled using a dry chemical, carbon dioxide or Halon extinquisher. (NTP, 1992)

Use water spray, foam, powder, carbon dioxide.

Fresh air, rest.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth.

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.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 60(SRC), determined from a water solubility of 2,400 mg/L(2) and a regression-derived equation(3), indicates that phenyl glycidyl ether is expected to have high mobility in soil(SRC). Volatilization of phenyl glycidyl ether from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 8.2X10-7 atm-cu m/mole(SRC), derived from its vapor pressure, 1.0X10-2 mm Hg(2), and water solubility(2). Phenyl glycidyl ether is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(2). A theoretical BOD range from 0 to 6% after 5 days using activated sludge(4,5) indicates that biodegradation may not be an important fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 60(SRC), determined from a water solubility of 2,400 mg/L(2) and a regression-derived equation(3), indicates that phenyl glycidyl ether is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 8.2X10-7 atm-cu m/mole(SRC), derived from its vapor pressure, 1.0X10-2 mm Hg(2), and water solubility(2). Epoxides in general hydrolyze rapidly at 25 °C and pH 7(4) through neutral, acid, or base-mediated reactions(5). Hydrolysis products are usually the corresponding diol and sometimes re-arranged products(5). According to a classification scheme(6), an estimated BCF of 8(SRC), from its water solubility(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A theoretical BOD range from 0 to 6% after 5 days using activated sludge(7,8) indicates that biodegradation may not be an important fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), phenyl glycidyl ether, which has a vapor pressure of 1.0X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase phenyl glycidyl ether is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 13 hrs(SRC), calculated from its rate constant of 2.9X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Phenyl glycidyl ether does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).

The substance can be absorbed into the body by inhalation of its aerosol and through the skin.

A medical surveillance program should include systematic collection and epidemiologic analysis of relevant environmental and biologic monitoring, medical screening, morbidity, and mortality data. This analysis may provide information about the relatedness of adverse health effects and occupational exposure that cannot be discerned from results in individual workers. Sensitivity, specificity, and predictive values of biologic monitoring and medical screening tests should be evaluated on an industry-wide basis prior to application in any given worker group.

The Koc of phenyl glycidyl ether is estimated as 60(SRC), using a water solubility of 2,400 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that phenyl glycidyl ether is expected to have high mobility in soil.

Chronic toxicity and oncogenicity were evaluated in groups of male and female Chr:CD rats (100/sex/group) receiving whole body exposure to phenyl glycidyl ether vapor at a nominal concentration of 0, 1.0 or 12ppm, six hours a day, five days a week for two years beginning at age 5 to 6 weeks. Survival among the high dose males was significantly lower than for the controls and exhibited a dose response relationship. Survival among low dose females was significantly lower than for controls with no dose-relationship exhibited. The frequency of neoplastic/non-neoplastic lesions contributing to the cause of death of both treated and controls was not statistically significant. Body weights of the high dose males were significantly greater than the controls, but due to the lack of food consumption data, it's biological significance is unclear. Total leukocyte counts tended to be slightly higher among high exposure male rats compared to controls. The 24 month sacrifice revealed a significantly greater incidence of nasal tumors (1 classified as adenoid epidermoid carcinoma and 12 various differentiated epidermoid carcinomas) in high dose male and female rats. After 24 months on study, high dose male and female rats exhibited a significantly greater frequency of rhinitis and squamous metaplasia or dysplasia of the respiratory epithelium and subepithelial gland in the anterior nasal cavity.

2,3-Epoxypropyl phenyl ether metabolized in rat and ferret to 3-(S-glutathionyl)-2-hydroxypropyl phenyl ether. /from table/

Rabbits and rats dosed with 1,2-epoxy-3-phenoxypropane excrete 2-hydroxy-3-phenoxypropionic acid and N-acetyl-S-2-hydroxy-3-phenoxypropyl)-L-cysteine. The administration produces a marked fall in hepatic glutathione level.

In vitro metabolic conjugation is catalyzed by glutathione-S-alkyltransferase.

Studies with PGE in rats and rabbits have shown evidence for two key mechanisms in the metabolism of PGE: hydrolysis of the epoxide group and glutathione conjugation. In rats, the capacity for glutathione (GSH) conjugation is limited and the ratio of GSH conjugation and hydrolysis decreases with increasing exposure to PGE. Urinary metabolites identified for rat following subcutaneous administration of PGE were 3-phenyloxylacetic acid (up to 94% of the administered dose) and small quantities of the mercapturic acid of phenyl glycidyl ether (N-acetyl-S-(2-hydroxy-3-phenoxypropyl)-L-cysteine) ... A novel metabolite (N-acetyl-O-phenylserine) derived from transamination from the epoxide hydrolysis pathway was described.

The urinary excretion of metabolites of phenyl glycidyl ether (PGE) and o-cresyl glycidyl ether (o-CGE) was investigated in rats. Urine was collected, in fractions, from rats intraperitoneally administered PGE or o-CGE in doses ranging from 0.033 to 1.0 mmol/kg. The metabolites were extracted from acidified urine with ethyl acetate or diethyl ether, and their identity was elucidated by GC/MS analysis. The epoxide of PGE can be inactivated by glutathione (GSH) conjugation or epoxide hydrolysis. After further metabolism, these routes lead to the urinary excretion of phenyl glycidyl ether mercapturic acid (PGEMA) and 3-(phenyloxy)lactic acid (POLA). The excretion of PGEMA and POLA was described before and is confirmed in this study. Additionally, a new metabolite was identified as N-acetyl-O-phenylserine (NAPS), which is proposed to be formed from POLA by subsequent oxidation, transamination, and N-acetylation. For PGEMA a linear dose-excretion relationship was found (r2 = 0.988), and the percentage of the dose excreted declined from 27% to 10% with increasing PGE dose. For NAPS also a linear dose-excretion relationship was found (r2 = 0.985), and NAPS accounted for 27% of the PGE dose. The excretion of PGEMA and NAPS was rather fast: 93% and 75%, respectively, of the respective total cumulative amounts excreted was already collected within 6 hr after administration.

Phenyl glycidyl ether percutaneous absorption rates were 13.5 mg/sq cm/hr in rats & 4.2 mg/sq cm/hr for rabbits.

Acute dermal treatment of rats and rabbits with PGE showed that the substance is well absorbed through the skin... .
