Description |
Colorless liquid with a mild odor; [NIOSH] |
Sources/Uses |
Used as a solvent for ethyl cellulose, nitrocellulose, printing inks; also used in the production of coatings and cements; [ACGIH] |
Comments |
Esters may induce narcosis in animals, but workers' exposures are limited by irritating effects. See appendix in: [Dick RB, et al. Chemicals in the workplace: incorporating human neurobehavioral testing into the regulatory process. Am J Ind Med. 1998 May;33(5):439-53.] |

Excerpts from Documentation for IDLHs |
The chosen IDLH is based on the statement by Browning [1965] that exposure to 4,000 ppm of a mixture of n-amyl acetate and isoamyl acetate produced complete loss of reflexes in rabbits within an hour [Koelsch 1912], and on the statement by Sax [1975] that 5,000 ppm n-amyl acetate produced deep narcosis in cats in 30 minutes. |
