Constituent 1
Method
- Type of population:
- general
- Subjects:
- - Number of subjects exposed: 50
- Sex: 15 males and 35 females
- Age: 28-69 (males) and 18-69 (females) years
Population examined included the following diagnoses on skin diseases:
Healthy: 9 males and 22 females
Sensitive skin: 7 females
Atopic skin: 6 males and 6 females - Ethical approval:
- not specified
- Route of exposure:
- dermal
- Reason of exposure:
- intentional
- Exposure assessment:
- measured
- Details on exposure:
- The undiluted test substance was applied once at 2 mg/cm² to healthy skin on the back area of the test subjects using a commercial test patch. The patch was removed 48 h post-application.
- Examinations:
- - Skin reactions: skin reactions were evaluated immediately after patch removal (48 h post-application) and 24 h later (72 h post-application).
-Scoring system:
0: no irritation
±: slight or doubtful erythema
+: clearly recognisable erythema
++: strong erythema and/or papulation
+++: densly aggregated papules and/or vesicles
++++: blistering or necrosis
Results and discussion
- Clinical signs:
- No positive or doubtful skin reactions were observed at 48 and 72 h post-application in any subject. Thus, there was no indication that the test substance acts as a primary skin irritant. Furthermore, no skin sensitisation was observed in any subject.
Applicant's summary and conclusion
- Conclusions:
- In a human patch test, the test substance was not irritating. Further, there was no evidence of skin sensitisation.
