Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- In a reliable study conducted using a protocol similar to OECD guideline 406, Lial 145 (C14-16 alcohols Type A) was not a skin sensitiser in guinea pigs (maximization procedure of Magnusson & Kligman).
