Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitizing
- Conclusions:
- The skin sensitization test for phenylacetic acid (103-82-2) was considered to be non- sensitizing to humans.
- Executive summary:
Skin sensitization test was performed on 25 human volunteers by maximization test at 2% concentration in petrolatum. After observation no skin sensitization reaction was noted. Hence phenylacetic acid (103-82-2) was considered to be non- sensitizing to humans.
