Description of key information
Skin: The primary dermal irritation potential of the test material was evaluated in rabbits under 4-hour semioccluded conditions (Glaza, 1997). The test material produced very slight to well-defined erythema and slight to moderate edema reactions. No other dermal irritation was observed. All irritation cleared by the Day 7 observation. The average of the 24-, 48-, and 72-hour scores are 1.2 for erythema and 1.3 for edema.
Eye: The primary eye irritation potential of the test material was evaluated when 0.1 mL was instilled into one eye of each of nine rabbits (six with treated eyes unwashed and three with treated eyes washed for 1 minute starting 30 seconds after instillation) (Glaza, 1997). The test material produced a corneal opacity in one animal and conjunctival irritation in all unwashed eyes which cleared in all animals by 96 hours after treatment. Positive irritation reactions were observed in five of the six animals with unwashed eyes which cleared in all animals by the 48-hour observation. In treated eyes receiving a washout, the test material produced only conjunctival irritation which cleared in all animals by 72 hours after treatment. Positive irritation reactions were observed in two of the three animals with washed eyes which cleared in all animals by the 48-hour observation. Rinsing the eyes after treatment did not have a substantial effect on the severity and persistence of ocular irritation.
The mean 24 -78 hour scores were: corneal opacity (0), iris lesions (0), conjuctival redness (0.9), and chemosis (0.1). Therefore, classification for eye irritation is not warrnated.

- Area of exposure: 6.25 cm2
- Type of wrap if used: The area of application was covered with a 4-ply 2.5-cm x 2.5-cm gauze patch secured with two strips of Micropore surgical tape. The trunk of the animal was then loosely overwrapped with a sheet of perforated plastic film that was secured on both ends with strips of Elastoplast® tape to provide a semiocclusive dressing.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): At the end of the 4-hour exposure period, the patches were removed and any remaining test material was removed from the test sites using mineral oil followed by liquid Ivory® soap mixed with warm tap water. The test sites were then rinsed with clean tap water and dried with disposable paper towels. The test material was removed from the test sites as thoroughly as possible without irritating the skin. The area of control skin was treated in the same manner.
SCORING SYSTEM:
Thirty minutes after removal of the test material, the degree of erythema and edema at each test site was read according to the Draize technique (recorded as the 4-hour score). Subsequent examinations were made at 24, 48, 72, and 96 hours and Day 7. An area of untreated skin on each animal was used for comparison. - Irritation parameter:

- Executive summary:
In an acute dermal irritation study in the New Zealand White Rabbit conducted to OECD guideline 404 in accordance with GLP, the primary dermal irritation potential of the test material was evaluated in rabbits under 4-hour semi-occluded conditions. The test material produced very slight to well-defined erythema and slight to moderate edema reactions. No other dermal irritation was observed. All irritation cleared by the Day 7 observation. The average of the individual index scores (the total of the erythema and edema scores at 4, 24, 48, and 72 hours divided by 4) is 2.8. The average of the 24-, 48-, and 72-hour scores are 1.2 for erythema and 1.3 for edema.
The mean value of the scores for erythema and edema formation for 24, 48 and 72 hours was calculated to be 1.2 and so will not be classified as irritating.
Reference
The average of the individual animal index scores is 2.8. The average of the 24-, 48-, and 72-hour scores are 1.2 for erythema and 1.3 for edema.

Positive irritation reactions were observed in two of the three animals with washed eyes which cleared in all animals by the 48-hour observation. Rinsing the eyes after treatment did not have a substantial effect on the severity and persistence of ocular irritation.
The mean value of the scores for cornea opacity, iris lesions, redness & oedema of the conjuctivae, for 24, 48 and 72 hours was calculated and was considered to be non-irritating according to the classification criteria.
Reference
The potential eye-irritancy of the substance was investigated in a study conduted in line with OECD guideline 405 under conditions of GLP. The test material when evaluated for its primary eye irritation potential in rabbits, produced a corneal opacity in one animal and conjunctival irritation in all treated eyes that were unwashed after treatment. All treated eyes in this group returned to a normal appearance by 96 hours after treatment with the exception that two animals exhibited hair loss around the treated eye. Positive irritation reactions were observed in five of the six animals with unwashed eyes which cleared in all animals by the 48-hour observation. In treated eyes receiving a washout after test material instillation, the test material produced only conjunctival irritation. All treated eyes in this group returned to a normal appearance by 72 hours after treatment. Positive irritation reactions were observed in two of the three animals with washed eyes which cleared in all animals by the 48-hour observation. Rinsing the eyes after treatment did not have a substantial effect on the severity and persistence of ocular irritation.

Additional information
The Glaza (1997) studies were chosen as the key studies for both skin and eye irritation as they were the most recent, guideline, and GLP studies. Multiple studies have been conducted with the registered material but many did not have sufficient information to fully evaluate the study. In addition, many of the skin irritation studies were not valid because the test material was either not removed from the skin or a solvent was used that may not have completely removed the test substance and/or irritated the skin. The registered substance is a viscous liquid and a mineral oil wipe step is necessary to completely remove the test material.
Justification for classification or non-classification
Skin:
The skin irritation observed in the key study was less than the classification criteria, therefore classification for skin irritation was not considered to be necessary.
Eye:
The eye irritation observed in the key study was less than the classification critieria, therefore classification for eye irritation was not considered to be necessary.
