Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Following a 4 hour semi-occlusive exposure to rabbits skin Kalcol 8098 was non-irritating to rabbit skin.
- Executive summary:
In a skin irritation study, 0.5 g test material moistened with 0.5 ml water was applied onto the skin of 3 rabbits and kept in contact to the skin under semi-occlusive dressing for 4 hours. The primary dermal iritation index was scored at 1, 24, 48 and 72 hours post-appliaction.
The test material produced a primary irritation index of 0.0. No evidence of skin irritation was noted during the study, all scores were 0.
The study was conducted according the appropriate OECD test guideline and in compliance with GLP.
