- 201-167-4
- EC Name:
- Trichloroethylene
- Cas Number:
- 79-01-6
- Molecular formula:
- C2HCl3
- IUPAC Name:
- 1,1,2-trichloroethene
- Reference substance name:
- trichloroethene
- IUPAC Name:
- trichloroethene
- Details on test material:
- - Name of test material (as cited in study report): trichloroethylene
- Analytical purity: > 99.95%
- Composition of test material, percentage of components: stabilized with thymol (10 mg/l)
- Storage condition of test material: packed in dark coloured glass bottles and stored at room temperature until use.

- Irritant / corrosive response data:
- Experiment 1 (rabbits treated with only one test substance):
Generally the following skin reactions were observed at one or more obervation time points, up to 72 hours afer treatment: well-defined erythema, very slight or slight ischemic necrosis (not after 4 hours) and very slight incrustation (after 72 hours only).
After 9 days, very slight erythema (in two rabbits) and very slight oedema, slight or severe scaliness and very slight, slight or moderate incrustation (in all three rabbits); after 16 days, very slight erythema (in one rabbit).
Experiment 2 (rabbits treated with four test substances at the same time):
Generally the following skin reactions were observed at one or more observation time points, up to 72 hours after treatment: well-defined or moderate erythema, very slight or slight oedema, very slight ischemic necrosis (not after 4 hours) and slight scaliness or slight incrustation (mainly after 72 hours).
After 9 days, very slight or well-defined erythema (in two rabbits), very slight or slight oedema (in all three rabbits), severe scaliness (in one rabbit) and moderate incrustation (in all three rabbits). After 16 days: very slight erythema (in one rabbit) and decreased hair growth (in two rabbits).
After five weeks all effects had cleared completely.
