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.
The test chemical was tested in 5 females (3 females for dose range finding study followed by 2 females for main study) Wistar rats at the doses of 200, 1000 and 2000 mg/kg body weight. Based on the individual body weight, the undiluted test item at the doses of 200 (0.20 mL/kg body weight), 1000 (1 mL/kg body weight) and 2000 (2 mL/kg body weight) - based on the density of the test item1.01 g/cm3(as per TIDS) was applied directly to the clipped skin of the animal to cover about 10% of the body surface of the animal (semi-occlusive). The applied area was covered with cotton gauze (size: Females: 8 x 5 cm of 6 ply) and it was secured in position by adhesive tape wound around the torso. The test item contact period with the skin was for 24 hours. After the 24 hours contact period, the dressing was removed and the applied area was washed with deionized water and wiped dry using clean towel.
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.
