Description of key information

Skin Irritation:

The dye was tolerated without irritation by all rabbits (index = 0). Under the test conditions described under FDA guidelines in the patch test, The test chemical can be assessed as not irritating to skin.

Eye Irritation:

After application of Solvent Blue 122, the highest irritation index of 16 was determined after 7 hours. According to the classification, the test chemical was therefore assessed to be slightly irritating to the eyes.

6 SPF-albino-Himalayan rabbit strain Hoe: HIMK (SPFWiga) were used for the study. The flank skin of 6 rabbits was depilated with an electric hair trimmer on two adjacent spots on a 3 × 3 cm area respectively. Either one of the clipped skin spots was additionally scarified using a scrape cutter. On 2.5 * 2.5 cm coarse lids of surgical gauze, 500 mg of the powdered dye was applied and glued to the prepared skin areas by means of an adhesive strip. The patches were covered by an infectious, impermeable, 6-8 cm wide PVC foil and then wrapped in an elastic permanent bandage. The exposure time was 24 hours.The dermal reactions were observed and scored after removal of the patches (24 hours) and 48 and 72 hours after the start of the test.

The dye was tolerated without irritation by all rabbits (index = 0). Under the test conditions described under FDA guidelines in the patch test, the test chemical can be assessed as not irritating to skin.

SCORING SYSTEM:The ocular lesions were observed and scored according to the classification given in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics, FDA, Austin, Texas, p. 51, 1975".

TOOL USED TO ASSESS SCORE: hand-slit lamp / biomicroscope / fluorescein: The assessment was performed 1,7,24,48 and 72 hours after the treatment with the help of a magnifying glass. After collecting the 24-hour report, all eyes were spooled with physiological saline solution.

Interpretation of results:
Category 2 (irritating to eyes) based on GHS criteria
Conclusions:
After application of the test chemical, the highest irritation index of 16 was determined after 7 hours. According to the classification, the test chemicalwas therefore assessed to be slightly irritating to the eyes.
Executive summary:

A test for mucous membrane compatibility of the test chemical was performed in rabbits. The test was performed according to the "1500.41 in Federal Register 38, No. 917, 27, 9, 173, P 27019" and FDA Guidelines.

6 SPF-albino-Himalayan rabbit strain Hoe: HIMK (SPFWiga) were used for the study. Single application of 100 mg of the powdered dye was instilled into the left conjunctival sac of 6 rabbits and the right eye remained untreated and served as control. The assessment for ocular lesions was performed 1, 7, 24, 48 and 72 hours after the treatment with the help of a magnifying glass. After collecting the 24-hour report, all eyes were spooled with physiological saline solution. After 48 hours and 72 hours, after instillation of a drop of fluorescein sodium in the dilution 1: 10000 = 0.001%. The ocular lesions were observed and scored according to the classification given in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics, FDA, Austin, Texas, p. 51, 1975".

For the determination of the irritation index, the evaluations of the cornea (a), the iris (b) and the conjunctiva (c) are added for each rabbit at the respective reading time. The average value of the values ​​of all rabbits is calculated at the corresponding reading time. The highest index determined at one of the reading times is used for grading.

After application of the test chemical, the highest irritation index of 16 was determined after 7 hours. According to the classification, the test chemicalwas therefore assessed to be slightly irritating to the eyes.

Additional information

Skin irritation:

A test for skin compatibility was performed to assess the dermal irritation potential of the test chemical. The test was performed according to the "1500.41 in Federal Register 38, No. 917, 27, 9, 173, P 27019" and FDA Guidelines.

6 SPF-albino-Himalayan rabbit strain Hoe: HIMK (SPFWiga) were used for the study. The flank skin of 6 rabbits was depilated with an electric hair trimmer on two adjacent spots on a 3 × 3 cm area respectively. Either one of the clipped skin spots was additionally scarified using a scrape cutter. On 2.5 * 2.5 cm coarse lids of surgical gauze, 500 mg of the powdered dye was applied and glued to the prepared skin areas by means of an adhesive strip. The patches were covered by an infectious, impermeable, 6-8 cm wide PVC foil and then wrapped in an elastic permanent bandage. The exposure time was 24 hours. The dermal reactions were observed and scored after removal of the patches (24 hours) and 48 and 72 hours after the start of the test.

The dye was tolerated without irritation by all rabbits (index = 0). Under the test conditions described under FDA guidelines in the patch test, the test chemical can be assessed as not irritating to skin.

Eye Irritation:

A test for mucous membrane compatibility of the test chemical was performed (Sustainability Support Services (Europe) AB has letter of access, 1977) in rabbits. The test was performed according to the "1500.41 in Federal Register 38, No. 917, 27, 9, 173, P 27019" and FDA Guidelines.

6 SPF-albino-Himalayan rabbit strain Hoe: HIMK (SPFWiga) were used for the study. Single application of 100 mg of the powdered dye was instilled into the left conjunctival sac of 6 rabbits and the right eye remained untreated and served as control. The assessment for ocular lesions was performed 1, 7, 24, 48 and 72 hours after the treatment with the help of a magnifying glass. After collecting the 24-hour report, all eyes were spooled with physiological saline solution. After 48 hours and 72 hours, after instillation of a drop of fluorescein sodium in the dilution 1: 10000 = 0.001%. The ocular lesions were observed and scored according to the classification given in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics, FDA, Austin, Texas, p. 51, 1975".

For the determination of the irritation index, the evaluations of the cornea (a), the iris (b) and the conjunctiva (c) are added for each rabbit at the respective reading time. The average value of the values ​​of all rabbits is calculated at the corresponding reading time. The highest index determined at one of the reading times is used for grading.

After application of the test chemical, the highest irritation index of 16 was determined after 7 hours. According to the classification, the test chemical was therefore assessed to be slightly irritating to the eyes.

Justification for classification or non-classification

Available studies indicate a possibility of the test chemical to cause eye irritation but no dermal irritation. Hence, comparing the annotations with the CLP regulation, the test chemical can be classified under the category “Not Classified” for skin irritation and “Category 2” for eye irritation.
