Description of key information

Skin irritation: Skin irritation studies of sufficient quality and conducted in a method comparable to OECD guideline 404 showed that the test substance was corrosive to rabbit skin.  

Eye irritation: An eye irritation study of sufficient quality and conducted in methods comparable to OECD guideline 405 showed that the test substance was corrosive to rabbit eyes. pH value of 11.7 indicated that the test substance was corrosive.

TEST SITE
- Area of exposure: All application sites were clipped free of fur and non-abraded. No further information was provided on the area of exposure.
- Type of wrap if used: Following the application of the test substance, one-inch square gauze patches were applied to the test site. The trunk of the animal was then wrapped with a rubber dam and an Ace bandage to retard evaporation.

- Washing (if done): At the end of the four hour exposure period, the wrappings were removed and the skin was wiped to remove any remaining test substance.
- Time after start of exposure: 4 hours

SCORING SYSTEM: Corrosion was considered to have resulted if the test substance in contact with the rabbit skin had caused destruction or irreversible alteration of the tissue on at least two out of each six rabbits tested. Tissue destruction was considered to have occurred if at any of the readings there was ulceration or necrosis.

- Diet (e.g. ad libitum): ad libitum (fresh Purina Rabbit Chow)
- Water (e.g. ad libitum): ad libitum (tap water)

Duration of treatment / exposure:

Observation period:

Number of animals:
6
Details on study design:
TEST SITE
- Area of exposure: Prior to treatment the fur was clipped from the backs and sides of the test animals with an Oster Model 2 clipper with an ANG-RA clipper head designed specifically for clipping rabbits. The left-side of the spinal column of each rabbit was abraded with a 21 gauge bent tip needle. The abrasions scratched the stratum corneum but did not reach the derma or produce bleeding. Three abrasions, approximately 2-3 cm apart, extending the length of the exposure site were made on each back. The right side of each back was not abraded. The test substance was applied to one abraded and one intact site per rabbit.
- Type of wrap if used: the test substance was covered with 2 ply gauze, 2.5 cm square. The patches were secured with adhesive tape and the entire trunk of the rabbit was wrapped with impervious material, 2 ml thick plastic.

REMOVAL OF TEST SUBSTANCE
- Washing (if done): no data

SCORING SYSTEM: the scoring system of Draize was used. The primary dermal index was calculated as cited in 16 CFR 1500.41. By definition, a primary irritatant was a substance which was not corrosive and had an empirical score of 5 or more (16 CRF 1500.3). See scoring scale below.
Irritation parameter:
primary dermal irritation index (PDII)
Basis:
mean
Time point:
other: combination of 48 and 72 hour observations
Score:
ca. 6.54
Max. score:
8
Reversibility:
no data
Irritant / corrosive response data:
The skin reactions observed were, in some instances, greater than the highest value on the Draize scale. These were noted as 4+. The test substance was therefore considered to be corrosive.

Additional information

Skin irritation

In one skin irritation study of sufficient quality and tested with methods similar to OECD guideline 404, 0.5 mL test substance was applied to the intact skin of rabbits (Pharmakon research International Inc, 1982; Klimisch 2). Animals were observed at 4 and 44 hours after treatment. Signs of necrosis were visible in two of six rabbits at the 4 hour reading and in five of six rabbits at the 44 hour observation period.

In another skin irritation study tested with methods similar to OECD guideline 404 (MB Research Laboratories Inc, 1979; Klimisch 2). 0.5 mL test substance was applied to non-abraded and abraded skin of rabbits. Animals were observed at 24 and 72 hours after treatment. The primary dermal index was determined to be 6.54 indicating corrosivity.

In a skin irritation study conducted in methods comparable to OECD guideline 404, 0.5 ml test substance was applied directly on the intact skin sites (Pharmakon Research International Inc, 1984; Klimisch 2). Animals were observed at 3 and 60 minutes and 4 hours after treatment. No signs were observed at the 1-3 minute observation period. Slight to moderate erythema was observed at the 60 minute and 4 hour observation periods. Signs of necrosis were visible in one animal at the 4 hour observation period.

In a similar study, 0.5 mL test substance was applied to non-abraded and abraded skin of rabbits for 1 hour (American Cyanamid company, 1968; Klimisch 4). Animals were observed 72 hours after treatment. The primary dermal index was determined to be 6.4. The degree of second degree chemical burn was moderate and diffuse.

An in vitro skin irritation study does not need to be conducted because adequate data from an in vivo skin irritation study are available.

Eye irritation

In one eye irritation study of sufficient quality and tested with methods similar to OECD guideline 405, 0.1 ml of the test substance was instilled into one eye of each rabbit (MB Research Laboratories Inc, 1979; Klimisch 2). The ocular reactions were graded at 1, 24, 48 and 72 hours and again at 7 days. If any corneal score was present on day 7, the eyes were scored again at 14 days. The maximum mean total scores (MMTs) were 41.3, 55.7, 66.6, 61.4, 57.3, and 72 at 1h, 24h, 48h, 72h, 7 day, and 14 day, respectively. Cornea and conjunctivae effects were not reversible within 14 days. The test substance was corrosive to rabbit eyes.

An in vitro eye irritation study does not need to be conducted because adequate data from an in vivo eye irritation study are available.

Justification for classification or non-classification

Based on the available data, a classification category 1C is warranted for skin irritation/corrosion.

Based on the available data, a classification category 1 (serious eye damage) is warranted for eye irritation.

No study is available on respiratory irritation. Data for classification is lacking.
