Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- 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 1.00, 0.00, 2.00, 1.00; 0.67, 0.00, 2.00, 1.00 and 0.67, 0.00, 2.00, 1.00 respectively. Under the experimental conditions tested, eye irritation and reversibility of effects on eyes of rabbits was observed within day 7. Hence, under the experimental test conditions, “Sodium salicylate (CAS No. – 54-21-7) is “Mildly Irritating to eyes” of New Zealand White female rabbit eyes and is being classified "Category 2"as per the CLPregulation.
- Executive summary:
Acute Eye Irritation/Corrosion Study of Sodium Salicylate (CAS: 54 -21 -7) in Rabbits, was performed in a OECD GLP laboratory (Sustainability Support Services (Europe) has letter of access).The study was performed according to OECD 405 Guidelines. 3 female young adult rabbits were used for the study.
Rabbits free from injury of eye were selected for the study. The eyes of all the rabbits were examined 24 hours prior to treatment. One eye of each rabbit served as control and other as treated. Control eye was left untreated whereas; 100 mgof test itemwas instilled in the other (treated) eye of each rabbit.The eye was observed at 1, 24, 48, 72 hour and on day 7 after test item instillation.Ophthalmoscope was used for scoring of eye lesions.
In the initial test,100 mg of test item (pulverized form)was instilled 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 a confirmatory test was conducted on additional two rabbits (animal no. 2 and 3);100 mgof test itemwas instilled into the conjunctival sac of right eye of both the rabbits and left eye served as the control. Ocular lesions were seen in animal no. 2 and 3 at 1, 24, 48 and 72 hour observation which recovered at day 7.
Untreated eye of all the three rabbits was normal throughout the experiment.
The following grading scores were observed in treated eye of treated rabbits.
Observation at 1 hour after instillation of test item revealed: Cornea-No ulceration or opacity in all 3 animals; Area of Opacity-Zero in all the animals;Iris:Normal in all the animals.Conjunctivae -Some blood vessels definitely hyperaemic (injected) was observed in all the animals;Chemosis:Some swelling above normal (includes nictitating membranes) was observed in all the animals.
Observation at 24 hours after instillation of test item revealed: Cornea-Scattered or diffuse areas of opacity (other than slight dulling of normal lustre); details of iris clearly visible in animal no. 1 whereas animal no. 2 and 3 showed no ulceration or opacity; Area of Opacity-One quarter (or less) but not zero in animal no. 1 and Zero in animal no. 2 and 3;Iris:Normal in all the animals.Conjunctivae –Diffuse, crimson color; individual vessels not easily discernible was observed in all animals;Chemosis:Some swelling above normal (includes nictitating membranes) was observed in all animals.
At 24 hours observation the rabbits were examined for corneal epithelium cell damage using sodium fluorescein strips and noticed 40%, 20%, 20% damage in animal no. 1, 2 and 3 respectively.
Observation at 48 hour after instillation of test item revealed: Cornea-Scattered or diffuse areas of opacity (other than slight dulling of normal lustre); details of iris clearly visible in all animals; Area of Opacity-One quarter (or less) but not zero in all 3 animals;Iris:Normal in all the animals.Conjunctivae –Diffuse, crimson color; individual vessels not easily discernible was observed in all animals;Chemosis:Some swelling above normal (includes nictitating membranes) was observed in all animals.
Observation at 72 hour after instillation of test item revealed: Cornea-Scattered or diffuse areas of opacity (other than slight dulling of normal lustre); details of iris clearly visible in all animals; Area of Opacity-One quarter (or less) but not zero in all 3 animals;Iris:Normal in all the animals.Conjunctivae –Diffuse, crimson color; individual vessels not easily discernible was observed in all animals;Chemosis:Some swelling above normal (includes nictitating membranes) was observed in all animals.
Observation on day 7 after instillation of test item revealed: Cornea- No ulceration or opacity in all the animals; Area of Opacity- Zero in all 3 animals; Iris: Normal in all the animals. Conjunctivae – Blood vessels were normal in all 3 animals; Chemosis: No swelling (Normal) was observed in all 3 animals.
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 1.00, 0.00, 2.00, 1.00; 0.67, 0.00, 2.00, 1.00 and 0.67, 0.00, 2.00, 1.00 respectively. Under the experimental conditions tested, eye irritation and reversibility of effects on eyes of rabbits was observed within day 7.
Hence, under the experimental test conditions, “Sodium salicylate (CAS No. – 54-21-7) is “Mildly Irritating to eyes” of New Zealand White female rabbit eyes and is being classified "Category 2"as per the CLP regulation.
