- Executive summary:
The aim of the study was to investigate acute toxic effects of the test substance after a single peroral administration to rats.
Methods and investigations were performed in conformance with the OECD-Guideline 423, 17 December 2001.
"DIMETHYLSUCCINYLOSUCCINATE" was administered once by stomach intubation to female Crl:CD(SD)IGS BR rats as a suspension in 0.1 % aqueous carboxymethyl cellulose. The dosing was performed sequentially to groups of 3 animals per step using a starting dose of 300 mg per kg body weight and 2000 mg per kg body weight as the second dose. The dose volume was 10 mL per kg body weight for all groups.
Investigations were performed as follow:
• Body weights: before administration, 7 and 14 days after the administration (p.a.).
• Clinical observations: at least once per day.
• Necropsy: The animals were sacrificed and necropsied 14 days p.a.
Findings were als follows:
• All animals survived until the scheduled termination of the study.
• Only the high dosed animals were affected. Piloerection and hunched posture, which are attributed to discomfort.
• All animals gained weight in both weeks p.a
• All animals were normal at the necropsy 14 d p.a.
• LD50, oral: > 2000 mg/kg body weight
