Materials and methods
- Type of study / information:
- Inhalation experiment in human subjects
- Principles of method if other than guideline:
- The object of the experiment was to evaluate on humans the effects of some common solvent vapour concentrations. It was thought that the information gained could then be used as a valuable supplemental to present industrial experience. The solvents studied included hydrocarbons, alcohols, ketones, esters and ethers. The ketone group included butanone.
- GLP compliance:
- no
Test material
- Reference substance name:
- Butanone
- EC Number:
- 201-159-0
- EC Name:
- Butanone
- Cas Number:
- 78-93-3
- Molecular formula:
- C4H8O
- IUPAC Name:
- butan-2-one
- Details on test material:
- - Name of test material (as cited in study report): Butanone
Constituent 1
Method
- Details on exposure:
- The experiment consisted of the exposure in a 1200 cubic foot gas cabinet of an average number of 10 people of both sexes to a given concentration of solvent vapour for a period of 3 to 5 minutes. After the exposure, each individual classified the effect of the vapour on the eyes, nose and throat. The classifications were: no reaction, slightly irritating and very irritating. The odour was reported as absent, definite, moderate, strong or overpowering. Finally all persons were asked if they believed they could work in the atmosphere for an 8 hour day. The subjects, except the experimenters were not told of the actual concentrations and whether or not the exposures to any one solvent were in order of increasing or decreasing concentration
Results and discussion
- Results:
- Butanone produced slight nose and throat irritation at 100 ppm. Mild eye irritation appeared in some subjects at 200 ppm. 300 ppm was conclusively rejected. A practical limit of 200 ppm is indicated (see table 1)

Applicant's summary and conclusion
- Conclusions:
- A sensory limit of 200 ppm of butanone is considered to be acceptable in providing comfortable working conditions.
