Erythema reaction in one subject


Applicant's summary and conclusion

Conclusions:
In a closed human patch study the test item was tested. Only in one subject erythema reactions were found. According to this result the test item is considered to be non sensitizing.
Executive summary:

In a closed human patch study the skin sensitizing potential of the test item was tested. The test was conducted with 7703 subjects suffering from dermatoses. The test item item was applicated to the upper inside of the arm. Ethanol 99% and a non-irritative cream base were used as vehicle. A concentration of 0.05 -0.5 % were applicated. Only in one subject erythema reactions were found. According to this result the test item can be considered as not sensitizing.
