Results
- Reading:
- 1st reading
- Group:
- test chemical
- Dose level:
- 0.1ml 0.01, 0.001, and 0.001% in saline
- Clinical observations:
- No dermal reaction were observed
- Remarks on result:
- no indication of skin sensitisation
Applicant's summary and conclusion
- Interpretation of results:
- other: Not sensitizing
- Conclusions:
- No signs of any skin allergic reaction were observed. Hence, Basic Violet 14 can be considered to be not sensitizing to guinea pig skin.
- Executive summary:
Skin sensitization test was performed using basic violet 14 as test material on guinea pigs. The test material was applied topically 5% in 25%Aqueous solution of gum Arabic to the skin of guinea pigs for 5 days. After 2 weeks of rest period the challenge treatment was provided by epicuteneous injection of concentration 0.1ml 0.01, 0.001, and 0.001% in saline. The guinea pigs were observed for signs of dermal sensitization after the challenge exposure.
No signs of any skin allergic reaction were observed. Hence, Basic Violet 14 can be considered to be not sensitizing to guinea pig skin.
