Test material
- Specific details on test material used for the study:
- - Principle of test:
Skin tolerance of the test item had previously been investigated in animals models. Because of its intended use, where it is widely used in the production of plastics, skin irritation potential in human adults also had to be investigated. Patch testing are widely used to predict irritating and allergenic properties of compounds and products intended for public use.
The study was conducted accordance with the following recommendations and guidelines;

- Short description of test conditions:
30 mg of test item was applied to 30 healthy caucasian volunteers for 24 h under occlusion. After 24 h the test site was cleaned and observations made (0h, 24, 48 h and 72 h after patch removal).
Volunteers were selected on the basis of questionnaire and by clinical inspection.
Inclusion criteria were;
Male or female
18-70 years old
Clean skin in testing area
Exclusion criteria were;
Outwith specified age range
Known allergy to plasters
Intake of antiallergic or antiinflammatory drugs in last 2 weeks
Inflammatory, eczematous or any other clinical sign of skin alterations in the test area
Moderate or severe ilness with last 2 weeks before exposure
Hyperpigmentation and multiple liver spots (lentigines) on possible test site
Extreme tanning of the skin of the test area
- Parameters analysed / observed:
Reading of skin reactions was conducted by the Principal Investigator or experienced staff member. Reactions were recorded on the CRF and graded on a 5 point scale;
0: negative (no reaction)
+: doubtful reaction
1: weak reaction (well-defined erythema)
2: moderate reaction (erthema with slight-moderate oedema)
3: strong reaction (vesicles and papules)
4: extreme reaction (bullous, spreading or other severe reaction)
Mean values were calculated (with standard deviation). An Overall Irrittion Score (OIS: sum of all reactions scores divided by the sum of readings) was calculated.
Method
- Type of population:
- general
- Ethical approval:
- no
- Remarks:
- Approval by Ethics Committes was considered as unnecessary because of the nature of the material and type of testing
- Subjects:
- 33 volunteers, 25 females and 8 males
- Clinical history:
- Vlunteers were age 18 - 70 years of age, with clean skin in the testing area.
No known allergic reaction to plasters
All volunteers had no history of;
Inflammatory, eczematous or any other clinical signs of skin alterations in the test area
Moderate or severe illiness within the last two weeks before exposure
Hyperpigmentation or multiple liver spots (lentigines) on possible test site - Controls:
- Liquid paraffin was given as control
- Route of administration:
- dermal
- Details on study design:
- TEST SITE

REMOVAL OF TEST SUBSTANCE
- Washing (if done): Not reported
- Time after start of exposure: 24 h
OBSERVATION TIME POINTS
(indicate if minutes, hours or days) 0, 24, 48 and 72 h after patch removal

Applicant's summary and conclusion
- Conclusions:
- The test item has irritating properties, at least under the exaggerated conditions of complete occlusive application.
- Executive summary:
In a clinical dermal irritation study, 33 healthy caucasian individuals (8 males, 25 female) were dermally exposed to 30 mg of Bisphenol AF 24 hours under occluded conditions. Individuals then were observed for 3 days. Irritation, including erythema and oedema formation, was scored numerically on a scale of 0 - 4 based on severity.
A weak reaction (well-defined erythema, max. score 1) was observed in 4 of the individuals at the 0 and 24 h observation period and 5 individuals at the 48 h observation period. With a combined score of 13 (4 / 4 / 5) out of 99 (33 / 33 / 33) readings, an Overall Irritation Score of 0.13 was calculated.
In this study, Bisphenol AF was found to have irritating properties at least under the exaggerated conditions of complete occlusive application.
