Results and discussion

Effect levelsopen allclose all
Remarks on result:
other: Butylene oxide does not present a problem from skin absorption under ordinary handling conditions. However, prolonged exposure to relatively large areas of skin may result in the absorption of toxic amounts.
Remarks on result:
other: The loss in body weight indicates that butylene oxide may have been absorbed through the skin to an appreciable extent.
Body weight:
Significant loss of body weight
