- Irritant / corrosive response data:
- The test item did not elicit any skin reactions at the application site following the initial three minute or one hour exposure (number 98 only).
Application of the test item to healthy intact rabbit skin for a duration of four hours resulted in a primary irritation score of 0.00.
The test item did not elict any skin reactions at the application site at any of the observation times (all scores 0). The mean values from 24 to 72 hours were therefore 0 for erythema and 0 for oedema.
No irreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin. - Other effects:
- VIABILITY/MORTALITY/CLINICAL SIGNS
No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.
COLORATION
Light yellow staining caused by the test item was observed at the test site of one female at the 1-hour reading.
BODY WEIGHTS
The body weights of all rabbits were considered to be within the normal range of variability.
