- Details on test animals or test system and environmental conditions:
- Test System:
Species, strain: Rabbit, New Zealand White (Kangda:NZW) SPF
Producer Qingdao Kangda Biotechnology Co., Ltd
Supplier Raonbio Inc., Republic of Korea
Justification for species selection: New Zealand White rabbits are commonly used in skin irritation studies having a large historical control database.
Sex, number, age and body weight range of animals (at receipt) Male, 5 rabbits, 16 weeks old, 2.52–2.67 kg
Sex, number, age and body weight range of animals (at the start of treatment) Male, 3 rabbits, 16–17 weeks old, 2.71–2.82 kg
Quarantine and acclimation
Upon receipt, all animals were subjected to the clinical examination. Body weights were recorded (CP12001S, Sartorius, Germany).
During the quarantine-acclimation period, all animals were observed for clinical signs once daily for 6 days in the initial test and for 8 days in the confirmatory test.
On the last day of the quarantine-acclimation period, the measurement of body weights and examination of health condition were conducted and the results were recorded for the study by a responsible person. All animals were judged to be healthy and acceptable for use in the study.
Animal and cage identification
During the quarantine-acclimation period, a temporary identification number was recorded on the inside of the left ear using a red indelible pen. Each cage was attached with an identification card for the quarantine-acclimation period.
Following group assignment, the animals were uniquely identified by recording the inside of the right ear with a blue indelible pen. Each cage was attached with a color identification card.
Group assignment
One day before application of the test substance, the dorsal surface of the rabbits was removed using hair clippers (Oster 5-50C U.S.A., size: 40, 1/10 mm). Three rabbits with good skin condition, without cuts or scratches, were selected for the initial test (one animal) and confirmatory test (two animals).
In order to protect the skin after group assignment, elizabeth kara was installed until the end of observation, but it was not installed during the period of occlusive dressing.
Disposition of remaining animals
Remaining animals not selected for the study were euthanized under pentothal sodium (JW Pharmaceutical Co., Ltd., Republic of Korea) anesthesia and discarded.

- Amount / concentration applied:
- Method of application:
A foam pad (3M Reston Self-Adhering Foam Pad, 3M Co., Ltd., U.S.A.), from which a 2.5 × 2.5 cm area was cut out, was placed on the application sites. The pulverized test substance of 0.5 g was applied on the test substance site using a spatula, moistened with 0.5 mL of water for injection (Lot No.: DBA7009, JW Pharmaceutical Co., Ltd., Republic of Korea) and a 2.5 × 2.5 cm lint patch (PIP Co., Ltd., Japan) was placed over the test substance site. An untreated 2.5×2.5 cm patch was placed over the control site. All application sites were covered with gauze (DaeHan Medical Supply Co., Ltd., Republic of Korea). Animals were wrapped loosely with an elastic bandage (3M Co., Ltd., Republic of Korea) and secured with a paper tape (Masking Tape, DAESUN Com., Republic of Korea) to form a semi-occlusive dressing. The residual test substance was gently wiped off the test substance site with cotton moistened with tepid water.
In the initial test, three test substance patches were sequentially applied to one animal. The first patch was removed at 3 minutes after application. Since no skin reaction was observed, the second patch was applied at a different site and removed at 1 hour after application. Since no skin reaction was observed, the third patch was applied and removed at 4 hours after application, and the response was graded.
A negative response was observed in the initial test. Therefore, a confirmatory test was conducted using additional two rabbits. In the confirmatory test, a single patch was applied and removed at 4 hours after application. - Duration of treatment / exposure:
- 4 hours
- Observation period:
- 72 hours
- Number of animals:
- 3
- Details on study design:
- TEST SITE
The back, dorsal surface of each animal was clipped one day prior to application of the test substance, and each site, approximately 2.5×2.5 cm, was selected as application site
REMOVAL OF TEST SUBSTANCE
The residual test substance was gently wiped off the test substance site with cotton moistened with tepid water.
OBSERVATION TIME POINTS
Dermal observations for erythema, eschar and edema formation were recorded at 1, 24, 48 and 72 hours after patch removal according to the evaluation of skin reactions (Method of Draize: 1959)1). No skin irritation was observed in both the initial and confirmatory tests at 72 hours after patch removal; therefore, no additional skin observations were conducted.
Clinical signs were observed once daily throughout the study.
SCORING SYSTEM:
The Draize scoring system was used, however any classification would be based upon GHS.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In conclusion, the test substance, Bisphenol-F(Reaction mass of 2,2’-methylenediphenol and 4,4’-methylenediphenol and o-[(4-hydroxyphenyl)methyl]phenol, did not show any evidence of skin irritation or corrosion in New Zealand White rabbits under the conditions of this study.
- Executive summary:
This study was conducted to evaluate the potential skin irritation/corrosion after a single dermal application of the test substance, Bisphenol-F (Reaction mass of 2,2’-methylenediphenol and 4,4’-methylenediphenol and o-[(4-hydroxyphenyl)methyl]phenol, in three 16–17-week-old male New Zealand White rabbits.
In the initial test, three test substance patches were sequentially applied to one animal’s clipped back. 0.5 g of pulverized test substance was placed on the test substance site and it was moistened with water for injection. In the initial test, the first patch was removed at 3 minutes after application, and the second patch at 1 hour after application and the third patch at 4 hours after application. No skin reaction was observed in the initial test, thus a confirmatory test was conducted using two additional animals. Observations of application sites for skin response were conducted at 1, 24, 48 and 72 hours after patch removal and scored according to the ‘Evaluation of skin reactions (Method of Draize: 1959)1), although classification was assessed according to GHS.
In both the initial and confirmatory tests, the test substance and control sites of all animals did not reveal any sign of adverse skin reactions such as erythema or edema at 1, 24, 48 and 72 hours after patch removal. The primary skin irritation index (P.I.I.) of the test substance was ‘0’. The test substance was classified as ‘Non irritant’.
During the observation period, no abnormal clinical signs or body weight gain was observed in any animal.
Based on the result of this study, the test substance, Bisphenol-F (Reaction mass of 2,2’-methylenediphenol and 4,4’-methylenediphenol and o-[(4-hydroxyphenyl)methyl]phenol, did not show any evidence of skin irritation or corrosion in New Zealand White rabbits under the conditions of this study.
