- Vehicle:
- other: sesame oil
- Details on oral exposure:
- MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg bw
DOSAGE PREPARATION (if unusual): Test material dissolved in the stated concentration in sesame oil and distributed homogeneously by means of a magnetic stirrer. Administered by gavage. - Doses:
- 2000 mg/kg bw

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The actue oral LD50 > 2000 mg/kg bw
- Executive summary:
An acute oral toxicity study was conducted on Branched CaDDBS (Phenylsulfonat CA) in Wistar rats at a limit dose of 2000 mg/kg bw using both male and female rats. No mortality or other toxic symptoms were observed. No effects on body weight gain were observed. The animals sacrificed at the end of the observation period showed no macroscopically visible changes. The resultant acute oral LD50 is >2000 mg/kg bw.
