- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Test Animal: Adult albino rabbits, Hra:(NZW)SPF, were procured, maintained individually in screen-bottom cages in temperature- and humidity-controlled quarters, provided access to water ad libitum and a measured amount of High Fiber Rabbit Chow® 5326, Purina Mills, Inc., and held for an acclimation period of at least 7 days. Animal husbandry and housing at HLA comply with standards outlined in the "Guide for the Care and Use of laboratory Animals”. If variations from the prescribed environmental conditions existed, they were documented and considered to have no effect on the study outcome. No contaminants were expected to have been present in the feed or water which would have interfered with or affected the results of the study.
Three male and three female acclimated animals, weighing from 2320 to 2436 g, were chosen at random for the test, and maintained during the observation period as specified for the acclimation period. Test animals were identified by animal number and corresponding ear tag.
Reason for Species Selection: Historically, the New Zealand White albino rabbit has been the animal of choice for evaluating the effect of chemicals on the skin. - Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- physiological saline
- Controls:
- no
- Amount / concentration applied:
- 0.5 g and moistened with 0.9% saline.
- Duration of treatment / exposure:
- 4 hours
- Observation period:
- 72 hours
- Number of animals:
- three males and three females.
- Details on study design:
- Approximately: 24 hours before treatment the hair was clipped from the back and flanks of each animal.
Preparation of Test Material: The sample was dosed as received.
Treatment: The test material was applied to the intact skin of each rabbit in the amount of 0.5 g and moistened with 0.9% saline. The treated area was covered with a 2.5 x 2.5 cm gauze patch secured with paper tape, loosely overwrapped with Saran Wrap® and secured with Elastoplast® tape to provide a semiocclusive dressing. Collars were applied to restrain the test animals for the 4-hour exposure period.
Reason for Route of Administration: Historically the dermal route is the route of choice based on the method of Draize.
Observations: After the exposure period, the patches were removed. The test sites were washed using lukewarm tap water and disposable paper towels. The test material was removed from the test sites as thoroughly as possible without irritating the skin. Thirty minutes following removal of the test material, the degree of erythema and edema was read according to the Draize technique (recorded as the 4-hour score). Subsequent examinations were made at 24, 48 and 72 hours after patch removal.
Individual body weights were taken just prior to study initiation.
Termination: At study termination all animals were euthanatized and discarded. - Irritation parameter:

- Executive summary:
To assess the relative level of primary skin irritation of a test material on rabbits under semi occluded conditions according to the U. S. Environmental Protection Agency's Guidelines for Testing Pesticides and Toxic Substances.
Regulatory Compliance: This study was conducted in accordance with the U.S. Environmental Protection Agency Good laboratory Practice Standards, 40 CFR 792 (November 29, 1983), the Food and Drug Administration Good Laboratory Practice Regulati9ns, 21 CFR 58, and the proposed Organisation for Economic Cooperation and Development's Principles of Good Laboratory Practice,
Annex 2, C(81)30. The in-life portion of the study was done before the effective date of the revised EPA standards (September 18, 1989).
The test material, Mark HP-10, was evaluated for its primary dermal irritation potential in male and female albino rabbits. The test material produced no dermal reactions at any of the observations. The average of the 4-, 24-, 48-, and 72-hour scores is 0.0 (considered to be non irritating).

- Details on test animals or tissues and environmental conditions:
- Test Animal: Adult albino rabbits, Hra:(NZW)SPF, were procured, maintained individually in screen-bottom cages in temperature- and humidity-controlled quarters, provided access to water ad libitum and a measured amount of High Fiber Rabbit Chow® 5326, Purina Mills, Inc., and held for an acclimation period of at least 7 days.

If variations from the prescribed environmental conditions existed, they were documented and considered to have no effect on the study outcome. No contaminants were expected to have been present in the feed or water which would have interfered with or affected the results of the study.
Three male and three female acclimated animals, weighing from 2020 to 2390 g, were chosen at random for the test.
Reason for Species Selection: Historically, the New Zealand White albino rabbit is the animal of choice based upon its large orbit and non pigmented iris. - Vehicle:
- not specified
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 0.04 g (0.1 ml weight equivalent)
- Duration of treatment / exposure:
- Single exposure
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 3 males & 3 females
- Details on study design:
- The animals' eyes were examined approximately 24 hours prior to test material administration using sodium fluorescein dye procedures. Only those animals with no sign of ocular injury or irritation were used on the test. Test animals were identified by animal number and corresponding ear tag.
Preparation of Test Material: A bulk density determination was made to determine the weight equivalent of a 0.1-ml dose. An individual dose of 0.04 g was weighed out for each animal.
Treatment: Each rabbit received 0.04 g (0.1 ml weight equivalent) of the test material placed into the everted lower lid of one eye, with the contralateral eye serving as the untreated control. The upper and lower lids were gently held together for 1 second to prevent loss of material and then released. The eyes of the rabbits remained unflushed.
Reason for Route of Administration: Historically, the ocular route is the route of choice based on the method of Draize.
Observations: The treated eyes were observed for ocular irritation at 1, 24, 48, and 72 hours after treatment.
At the 72-hour reading, sodium fluorescein was used to aid in revealing possible corneal injury. Irritation was graded and scored according to the Draize technique.
Animals were weighed just prior to test material administration.
Termination: At study termination all animals were euthanatized and discarded.
Statistical Methods: No statistical method was performed. - Irritation parameter:

Additional information
Skin Irritation/Corrosion
To assess the relative level of primary skin irritation of a test material on rabbits under semi occluded conditions according to the U. S. Environmental Protection Agency's Guidelines for Testing Pesticides and Toxic Substances. The in-life portion of the study was done before the effective date of the revised EPA standards (September 18, 1989).
The test material, Mark HP-10, was evaluated for its primary dermal irritation potential in male and female albino rabbits. The test material produced no dermal reactions at any of the observations. The average of the 4-, 24-, 48-, and 72-hour scores is 0.0 (considered to be non irritating).
Eye Irritation
To assess the relative level of irritation produced following a single exposure of a test material to one eye of albino rabbits. The in-life portion of the study was done before the effective date of the revised EPA standards (September 18, 1989).
The test material, Mark HP-10, produced iridal involvement and moderate to severe conjunctival irritation when instilled into the eyes of six albino rabbits. All ocular irritation cleared within 72 hours after instillation of the test material.
Justification for selection of skin irritation / corrosion endpoint:
Endpoint conclusion dervied using a GLP compliant study.
Justification for selection of eye irritation endpoint:
Endpoint conclusion dervived using a GLP compliant study.
Justification for classification or non-classification
Based on the avaiable data the substance does not trigger any of the requirements for classification, therefore the substance is Not Classified as a skin or eye irritant.
