Male rats (number not given) were given a single oral dose of 8.7 mmol/kg [1-(14)C]methoxyisopropyl acetate. Approximately 64% of the administered radioactivity was exhaled as (14)CO2and 24% was excreted in urine within 48 hr of the oral dose. Free methoxyisopropanol and methoxyisopropanol sulfate and glucuronide conjugates were identified in the urine.
... Male F344 rats (number not given) were exposed to 3000 ppm [1-(14)C]methoxyisopropyl acetate in an inhalation chamber for 6 hr. Approximately 53% of the administered radioactivity was exhaled as (14)CO2,and 26% was excreted in urine within 48 hr of the end of the inhalation expo sure period. Methoxyisopropanol and sulfate and glucuronide conjugates were identified in the urine.

... The rate of hydrolysis of methoxyisopropyl acetate by carboxylesterase /were measured/ in the nasal mucosa of mice, rats, rabbits, and dogs. Samples of nasal mucosal tissue from each species were incubated in vials with 1.0 to 23 mM methoxyisopropyl acetate for 10 min, and then centrifuged. The supernatant was removed and analyzed by gas chromatography to measure the methoxyisopropanol content. The apparent Vmax and Km for the hydrolysis of methoxyisopropyl acetate were 0.080 x 10(-3) M/min and 2.67 x 10(-3) M, respectively.
The similarities between the metabolism and disposition of methoxyisopropyl acetate and those previously observed in methoxyisopropanol indicated that methoxyisopropyl acetate is rapidly hydrolyzed to methoxyisopropanol.
IDENTIFICATION AND USE: 1-Methoxy-2-propyl acetate is used as a solvent in cosmetic formulations, as well as in surface coatings, inks, and cleaners. HUMAN STUDIES: The substance defats the skin, which may cause dryness or cracking. It is irritating to the eyes and respiratory tract. Exposure at high levels could cause depression of the central nervous system. ANIMAL STUDIES: Watery eyes, anorexia, rapid shallow breathing, and excess salivation were observed in rats given a single dose of 4000, 6300, or 10,000 mg/kg 1-methoxy-2-propyl acetate. 1-Methoxy-2-propyl acetate was not a skin irritant in rabbits. 10% 1-methoxy-2-propyl acetate in water was not a sensitizer in a guinea pig maximization test. Some slight changes were observed in the appearance of renal tissues in rats exposed to 3000 ppm 1-methoxy-2-propyl acetate. Slight to moderate degeneration of the olfactory epithelium in the nasal cavities was seen in rats and in mice. 1-Methoxy-2-propyl acetate had no adverse effect on reproductive parameters in rat developmental studies. 1-Methoxy-2-propyl acetate did not induce mutations or toxicity in Salmonella typhimurium strains TA98, TA100, TA1535, or TA1537 or in Escherichia coli WP2 uvrA, with or without metabolic activation.
