Constituent 1
Method
- Details on study design:
- - Number of subjects exposed: 80
- Sex: male/female
- Age: 16-45
- Race: Asian
- Demographic information: Japan, from Tokyo and Osaka
- No clinical history provided. - Details on exposure:
- TYPE OF TEST(S) USED: patch test (epicutaneous test)
ADMINISTRATION
- Type of application: occlusive
- Description of patch: A piece of lint of about 1 cm2, was applied to the test area. A cellophane of 2 cm2 was placed on the lint and then covered with a plaster of 4 cm2.
- Vehicle / solvent: base cream or 99 % ethyl alcohol
- Concentrations: 0.03-0.5 %
- Testing/scoring schedule: test for 24 to 48 h, reading 30 min after removal
- Other: The application was done on the back, the flexor aspect of the forearm and the inside of the upper arm. The test was carried out 1-3 times per month from September to next May, the summer season being excluded.
EXAMINATIONS
- Grading/Scoring system: - No visible reaction; +/- Slight erythema; + Erythema; ++ Erythema and swelling or marked erythema
Results and discussion
- Results:
- No signs of skin irritation were observed in any of the subjects.
Applicant's summary and conclusion
- Conclusions:
- Patch test in 80 Japanese with the test substance (0.03-0.5 %) showed no skin irritation potential.
- Executive summary:
A patch test with 80 Japanese was conducted with the test substance (0.03-0.5 %). The application time was between 24 to 48 h and the concentration used was 0.03-0.5 % in base cream. Evaluation of the test side 30 min after exposure determination showed no skin irritating potential of the test substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
