Materials and methods

Test guideline

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 401 (Acute Oral Toxicity)

Principles of method if other than guideline:

BASF-Test: The study was conducted according to an internal BASF method which in principle is comparable to the OECD Guideline 401.
A test group consisting of 5 animals/sex was treated by single gavage application with an aqueous solution of the test substance. The animals were observed for mortality and for clinical symptoms of toxicity. At the end of the observation period of 14 days, the surviving animals were sacrificed for the purpose of necropsy; animals that died during the observations period also were subjected to necropsy.

GLP compliance:

no

Test type:

standard acute method

Applicant's summary and conclusion

Executive summary:

In an oral toxicity study, comparable to OECD 401, dipropylenetriamine was administered to Sprague-Dawley rats (10animals/sex/dose) at 464 to 1470 mg/kg in single dosages (gavage) followed by a 14-day observation period.The LD50 was ca. 700 mg/kg bw.
