Results were expressed as the 10 min time weighted average in the air (TWA10) and as the peak concentration in the breathing zone of the 'user'. Following a 10 s use of hairspray containing 50% dimethyl ether or 26% liquefied petroleum gas, time weighted average in the air values for an adult user in a closed room (volume 21 cu m) were on average 114 ppm and 73 ppm respectively.

Exposures were terminated if unconsciousness occurred in the subjects. The number of subjects tested in each group was not reported. ...Clinical symptoms were noted for all concentrations. Effects on reaction times were tested at all dose levels, memory (writing of the Lord's Prayer) was tested at 82,000 and 100,000 ppm, muscular coordination (as exemplified by the act of writing) was observed at 82,000, 100,000, and 144,000 ppm, and typewriting was tested at 100,000 ppm. In human subjects, 50,000 and 75,000 ppm of DME caused feelings of mild intoxication but no objective symptoms beyond slight lack of attention after 12-minutes exposure to the higher concentration. At 82,000 ppm, some incoordination developed after 21.5 minutes, and a complaint was made of indistinct vision. At 100,000 ppm, no objective symptoms occurred during the first 15 minutes. Distinct signs of incoordination developed after 21 minutes of exposure. The experiment continued for 64 minutes, with the subject unable to do simple tasks (i.e., balancing of the head required special effort, estimation of time was lost, simple multiplication and memory were affected). At 144,000 ppm, symptoms first occurred after 7 minutes with the subject losing consciousness after 26 minutes.
