In a study to investigate the chemosensory properties of tertiary butyl
acetate, male and female test subjects were exposed to analytically
verified vapor concentrations of the test material in a controlled
setting and asked to judge odor and sensory irritation. Data
values were reported as the points of 50% detection above chance. For
tertiary butyl acetate, the odor threshold occurred at 8 ppb. For
sensory irritation, detection at 50% occurred at 177 ppm. There
were no significant differences in response between male and female test
subjects for either odor detection threshold or sensory irritation
threshold. The LOAEL for sensory irritation for
typical test subjects was 177 ppm and the NOAEL was 47 ppm. The
LOAEL for sensitive individuals was considered to be 47 ppm and the
NOAEL 11 ppm.
