Applicant's summary and conclusion
- Interpretation of results:
- other: not irritating
- Conclusions:
- There was no skin reaction observed at test item applied area. The mean erythema and edema scores were 0.0 at all observation times. Hence, it was concluded that the test chemical was Non-Irritating to the skin of Wistar rats under the experimental conditions tested and classified as “Category-Not Classified” as per CLP Classification.
- Executive summary:
A study was designed and conducted to determine the dermal reaction profile of the test chemical in Wistar rats. The study was performed as per OECD Guidelines 402 and complying to the GLP procedures.
1 female for the dose range finding study, followed by additional 2 females rats for main study.
Based on the individual body weight, the test item at the dose of 2000 mg/kg body weight was weighed on an aluminum foil and made as a paste in Milli-Q water and applied directly to the clipped skin (clipping was done approximately 24 hour prior to application) of the animal to cover about 10% of the body surface of the animal (semi-occlusive). The area of application was covered with cotton gauze (size: Females: 8 x 5 cm of 6 ply) and it was secured in position by adhesive tape wrapped around the torso. The test item contact period with the skin was for 24 hours.
After the 24 hours contact period, the adhesive tape and cotton gauge was removed and the applied area was washed with deionized water and wiped dry using clean towels.
All the rats were observed for clinical signs of toxicity and mortality for 14 days post application. In addition, the treatment site was observed at 24, 48 and 72 hours after removal of test item using the Draize criteria. There were no clinical signs of toxicity and mortality.
There was no skin reaction observed at test item applied area. The mean erythema and edema scores were 0.0 at all observation times. Hence, it was concluded that the test chemical was Non-Irritating to the skin of Wistar rats under the experimental conditions tested and classified as “Category-Not Classified” as per CLP Classification.
