Test material

Test system

Details on study design:
The corrosive potential of T-159 was investigated according to OECD 431. An amount of 25 mg T-159 and 25 µl water was applied to 3-D human skin models (EPI-200).

In vivo

Irritant / corrosive response data:
After termination of a 3-min and a 1-hr period cell viability was measured: 104% after 3 min - 90% after 1 hr as compared to controls. Classification: non-corrosive
