Description of key information
Skin Irritation:
The Primary Irritation Index (PII) for the test chemical after 14 days of observation was 0.0. Also the test chemical did not produce any clinical signs of toxicity throughout the examination period of 14 days.
Hence, under the test conditions, the test chemical can be concluded to be not irritating to New Zealand White rabbit skin.
Eye Irritation:
The individual mean score for animal nos. 1, 2 and 3 at 24, 48, 72 hours for corneal opacity, iris, conjunctiva and chemosis were found 0.00, 0.00, 0.00, 0.00; 0.00, 0.00, 0.00, 0.00 and 0.00, 0.00, 0.00, 0.00, respectively. Hence under the experimental test conditions, the test chemical can be considered as “Non Irritant” to New Zealand White female rabbit eyes.

A dermal irritation study was conducted on New Zealand white rabbits in accordance with OECD 404 to assess the irritation parameter of the test chemical. 3 female New Zealand White rabbits were used for the study. The animals were prepared 24 hrs prior to application of test product. The furs from the dorsal area of trunk of animals were removed with electric
clippers exposing an area measuring approximately 6 cm2 of body surface area of animal. The care was taken such that abrasion penetrated the Stratum corneum only and not dermis. 0.5 gm of the test compound was applied on a small area 6 square cms of the intact test site. Each site of application was covered with an impervious dressing which was secured with an adhesive tape. The animals were housed individually and restrained by the use of plastic collars. After patch removal [4 hours later] the unabsorbed test chemical was removed and the test site was washed with lukewarm water. The intact skin site of application was observed for erythema and edema at 1, 24,48 and 72 hours till 14 days after application and scored according to Draize method.
The Primary Irritation Index (PII) for the test chemical after 14 days of observation was 0.0. Also the test chemical did not produce any clinical signs of toxicity throughout the examination period of 14 days.
Hence, under the test conditions,the test chemical can be concluded to be not irritating to New Zealand White rabbit skin.

- Executive summary:
Acute Eye Irritation/Corrosion Study of test chemical in Rabbits was performed as per OECD guideline no. 405.
3 female New Zealand White Rabbits free from injury of eye were selected for the study. The eyes of all the rabbits were examined 24 hours prior to treatment.
The test compound in the amount of 0.1 gm was applied as such and then placed in the conjunctival sac of one eye of each animal after gentle pulling the lower eye lid away from the eye ball. The eye lids were then gently held together for about one second to prevent the loss of the material. The other eyes which remains untreated, served as control. The eyes of the test animal were not washed for at least 24 hours following instillation of the test compound. After 24 hours, eyes were washed gently with the luke warm water. The eye was observed at 1, 24, 48 and 72 hours after test item instillation.
In the initial test, 0.1 ml of test item was applied into the conjunctival sac of the right eye of animal no.1 whereas the left eye of the rabbit served as the control. As animal no. 1 showed no severe ocular lesions till 24 hour observation hence a confirmatory test was conducted on additional two rabbits (animal no. 2 and 3); 0.1 ml of test item was instilled into the conjunctival sac of right eye of both the rabbits and left eye served as the control. There were no other signs observed through out the observation period of 21 days.
The individual mean score for animal nos. 1, 2 and 3 at 24, 48, 72 hours for corneal opacity, iris, conjunctiva and chemosis were found 0.00, 0.00, 0.00, 0.00; 0.00, 0.00, 0.00, 0.00 and 0.00, 0.00, 0.00, 0.00, respectively. Hence under the experimental test conditions, the test chemical can be considered as “Non Irritant” to New Zealand White female rabbit eyes.

Additional information
Skin Irritation
A dermal irritation study was conducted on New Zealand white rabbits in accordance with OECD 404 to assess the irritation parameter of the test chemical. 3 female New Zealand White rabbits were used for the study. The animals were prepared 24 hrs prior to application of test product. The furs from the dorsal area of trunk of animals were removed with electric
clippers exposing an area measuring approximately 6 cm2 of body surface area of animal. The care was taken such that abrasion penetrated the Stratum corneum only and not dermis. 0.5 gm of the test compound was applied on a small area 6 square cms of the intact test site. Each site of application was covered with an impervious dressing which was secured with an adhesive tape. The animals were housed individually and restrained by the use of plastic collars. After patch removal [4 hours later] the unabsorbed test chemical was removed and the test site was washed with lukewarm water. The intact skin site of application was observed for erythema and edema at 1, 24,48 and 72 hours till 14 days after application and scored according to Draize method.
The Primary Irritation Index (PII) for the test chemical after 14 days of observation was 0.0. Also the test chemical did not produce any clinical signs of toxicity throughout the examination period of 14 days.
Hence, under the test conditions, the test chemical can be concluded to be not irritating to New Zealand White rabbit skin.
Eye Irritation
Acute Eye Irritation/Corrosion Study of test chemical in Rabbits was performed as per OECD guideline no. 405.
3 female New Zealand White Rabbits free from injury of eye were selected for the study. The eyes of all the rabbits were examined 24 hours prior to treatment.
The test compound in the amount of 0.1 gm was applied as such and then placed in the conjunctival sac of one eye of each animal after gentle pulling the lower eye lid away from the eye ball. The eye lids were then gently held together for about one second to prevent the loss of the material. The other eyes which remains untreated, served as control. The eyes of the test animal were not washed for at least 24 hours following instillation of the test compound. After 24 hours, eyes were washed gently with the luke warm water. The eye was observed at 1, 24, 48 and 72 hours after test item instillation.
In the initial test, 0.1 ml of test item was applied into the conjunctival sac of the right eye of animal no.1 whereas the left eye of the rabbit served as the control. As animal no. 1 showed no severe ocular lesions till 24 hour observation hence a confirmatory test was conducted on additional two rabbits (animal no. 2 and 3); 0.1 ml of test item was instilled into the conjunctival sac of right eye of both the rabbits and left eye served as the control. There were no other signs observed through out the observation period of 21 days.
The individual mean score for animal nos. 1, 2 and 3 at 24, 48, 72 hours for corneal opacity, iris, conjunctiva and chemosis were found 0.00, 0.00, 0.00, 0.00; 0.00, 0.00, 0.00, 0.00 and 0.00, 0.00, 0.00, 0.00, respectively. Hence under the experimental test conditions, the test chemical can be considered as “Non Irritant” to New Zealand White female rabbit eyes.
Justification for classification or non-classification
Available results from the Guideline studies indicate a very strong possibility that the test chemical lacks the potential to cause any irritation to eyes and skin. Hence, the test chemical can be considered to be not irritating to eyes and skin. It can be further classified under the category “Not Classified” as per CLP regulation.
