Strain:
New Zealand White
Details on test animals or test system and environmental conditions:
Male New Zealand White Rabbits ten to twelve weeks old, weighing between 2.57 and 2.70 kilograms at the start of the study were individually housed in stainless stell cages in a temperature, humidity and light controlled room. Purina Rabbit chow and water were available ad libitum. The animals were conditioned for at least 5 days prior to study initiation.
Type of coverage:
semiocclusive
Preparation of test site:
clipped
Vehicle:
unchanged (no vehicle)
Amount / concentration applied:
0.5 mL of neat test material
Duration of treatment / exposure:
The day before study initiation, electric clippers were used to remove the hair from the left side of the
trunk, from the midline of the back to the abdomen. The following day a 0.5 ml aliquot of the neat test
material was then applied to an area approximately 6 square centimeters on the side of the test animal.
The application site is located approximately 5-7 centimeters down from the backbone. The test
substance was then covered with a 2.5 cm² - 2 layer gauze patch held in place with non-irritating Kendall
Curity Standard Porous Tape and the patch was then covered with a semi-occlusive plastic overwrap
secured in place with Kendall Curity Standard Porous Tape for the duration of the exposure period. At
the end of the 4 hour contact period, residual material was removed from the site; and 30 minutes after
removal, the site was observed and scored
Observation period:

Remarks on result:
no indication of irritation
Irritation parameter:

Reversibility:

Remarks on result:
no indication of irritation
Interpretation of results:
GHS criteria not met
Conclusions:
In accordance with GHS and OECD 404 guidelines, the substance is not classified for skin irritation
Executive summary:

The test susbtance was applied at a dose of

0.5 ml to an unabraded site on a clipped area of each of three albino rabbits. The application

sites were graded for indication of skin reactions at 0.5, 24, 48, 72 and 168 hours after test

substance removal. There were minor skin irritation reactions in all of the test subjects. The

maximum skin irritation score was 1.33 at the 24 hour observation.

In accordance with GHS and OECD 404 guidelines, the substance

is not classified for skin irritation.

Species:

Strain:

Details on test animals or tissues and environmental conditions:
Male New Zealand White Rabbits ten to twelve weeks old, weighing between 2.57 and 2.70 kilograms at the start of the study were individually housed in stainless stell cages in a temperature, humidity and light controlled room. Purina Rabbit chow and water were available ad libitum. The animals were conditioned for at least 5 days prior to study initiation.
Vehicle:
unchanged (no vehicle)
Controls:
other: The contralateral eye to treatment served as the untreated control for each rabbit
Amount / concentration applied:
0.1 mL of undiluted test sample
Duration of treatment / exposure:
Three animals were dosed by instilling 0.1 mL of the test article into one eye and then holding the eye lids together for one second to prevent loss of the material. The contralateral eye served as the untreated control for each rabbit.

Conclusions:
The test susbtance is not considered to be irritating to the eye.
Executive summary:

The test substance was administered into one eye of each of three albino rabbits. The eyes were observed and

scored at 1, 24, 48 and 72 hours. There was minimal irritation observed in all of the test subjects

and the maximum group mean score was 10.67/110.0 at the 1 hour observation. All irritation

cleared within 72 hours. In accordance with GHS and OECD 405 guidelines, the substance is not classified for eye irritation.

Additional information

In an OECD 404 acute dermal irritation/corrosion study in male New Zealand rabbits, minor skin irritation reactions were observed in all test subjects. The maximum skin irritation score was 1.33 at the 24 -hour oversation. The primary skin irritation index was calculated to be 1.08. All irritation cleared within 7 days.

In an OECD 405 acute eye irritation/corrosion study in male New Zealand rabbits, minimal irritation was observed in all test subjects. The maximum group mean score was 10.67/110.0 at the 1 -hour observation. All irritation cleared within 72 hours.

In vitro skin and eye irritation/corrosion studies are not available; these do not need to be conducted since adequate data are already available from in vivo studies.

No data are available on respiratory irritation. However, exposure of humans via inhalation is considered unlikely.

Justification for classification or non-classification

Based on the available data, the substance is not classified for skin or eye irritation/corrosion in accordance with Regulation (EC) No. 1272/2008.
