- Conclusions:
- The skin irritation property of the registration substance is assessed based on the read-across to Sodium N-cocoyl glycinate.
Sodium N-cocoyl glycinate was investigated for its skin irritation property according to the Guideline OECD 404. It is not skin irritating.
Likewise the registration substance is not skin irritating. - Executive summary:
The skin irritation property of the registration substance is assessed based on the read-across to Sodium N-cocoyl glycinate.
Sodium N-cocoyl glycinate was investigated for its skin irritation property according to the OECD 404. 0.5 ml of the test material was semi occusively applied to the clipped skin area of rabbits for 4 hours. Three animals were treated. Mild erythema and edema was found in all treated animals and these effects disappeard within 14 days. Sodium N-cocoyl glycinate is not skin irritating.
Likewise, the registration substance is not skin irritant.
