Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The LD 50 value for the New Zealand white rabbits by 3-Phenoxybenzylalcohol (CAS No: 13826-35-2) was found to be 10000 mg/kg.
Executive summary:

Acute toxicity test (Dermal) inNew Zealand white rabbits by 3-Phenoxybenzylalcohol (CAS No: 13826-35-2) was performed.

8 Male and 8 female animals were used for the study at 2500, 5000, 10000 and 20000 mg/kg.They were individually housed in hanging wire-mesh cages in temperature and humidity controlled quarters.The rabbits weighed from 2318 to 2925 grams at the beginning of the study.Body weights were measured initially and at 7 and 14 days.They were maintained in accordance with the recommendations contained in H.E.W. Publication No. 74-23 (N.L.H.) entitled "Guide for the Care and Use of Laboratory Animals.

The hair was removed from the back of each rabbit. The skin of one male and one female in each group was abraded with a scalpel blade.The test material was applied once only to the backs of the rabbits. The area wrapped with gauze bandaging and occluded with Saran Wrap and observed for 14 days. Gross necropsy was done if some rabbits were died during 14 days and at the end of 14 days.

 

From the above study and observations, the LD 50 value for the New Zealand white rabbits by 3-Phenoxybenzylalcohol (CAS No: 13826-35-2) was found to be 10000 mg/kg.
