Method

Subjects:
No precise description of the 2 populations concerned:
- Workers involved in the manufacture of thioglycolic acid 2-ethylhexyl ester;
- Laboratory workers involved in the study of the effects of thioglycolic acid 2-ethylhexyl ester on the blood pressure of rabbits and dogs (See Hollenbach et al. (1972)/Specific investigations Blood pressure 01) esposed to the substance for several days.
Route of exposure:
other: no data
Reason of exposure:
intentional, occupational
Exposure assessment:
not specified

Results and discussion

Clinical signs:
- Workers involved in the manufacture of thioglycolic acid 2-ethylhexyl ester frequently complained of headaches, dizziness, tiring, general weariness and gastrointestinal symptoms. Circulatory stimulants alleviated the syndrome for a short time in some cases, so that the cause was assumed to be a hypotensive effect.

- Laboratory workers involved in the study of the effects of thioglycolic acid 2-ethylhexyl ester on the blood pressure of rabbits and dogs complained of symptoms of thy type and particularly of headaches. The laboratory workers were also in contact with thioglycolic acid and ethanol for the same period as the study period with thioglycolic acid 2-ethylhexyl ester.

Applicant's summary and conclusion

Executive summary:

As part of a study for assessing effects of exposure to 2 -EHTG on blood pressure of rabbits and dogs, clinical observations of symptoms of workers exposed to the substance were reported.

Workers involved in the manufacture of thioglycolic acid 2-ethylhexyl ester frequently complained of headaches, dizziness, fatigue, general weariness and gastrointestinal symptoms. Circulatory stimulants alleviated the syndrome for a short time  in some cases, so that the cause was assumed to be a hypotensive effect. The laboratory workers involved in the study of the effects of  thioglycolic acid 2-ethylhexyl ester on the blood pressure of rabbits and  dogs similarly complained of symptoms of this type and particularly of  headaches, after exposure to thioglycolic acid 2-ethylhexyl ester for  several days. The laboratory workers were also in contact with thioglycolic acid and ethyl hexanol (no further details provided).
