Any other information on results incl. tables
In this Repeated Dose, 28-day Oral Toxicity Study performed comparable to OECD guideline 407, 12 May 1981 reaction products of C16-18/C18 unsaturated fatty acid with methyl diethanolamine, MeCl quaternized (10 % a.i aqueous dispersion) was administered to groups of 25 Charles River CD rats male and female by oral gavage at dose levels of 1, 10 and 500 mg/kg bw/day for 28 days. Two other control groups received either deionised water or to pH 2.5 adjusted (HCL) deionised water (vehicle).
All animals survived to study termination. No test substance-related findings were detected or observed in clinical examinations, body weights, food consumption values, opthalmoscopic examinations, haematology, clinical biochemistry or clinical pathology evaluations including organ weights of ovary and testis and histopathology of reproductive organs (gonads, mammary gland (femals only), prostate and seminal vesicle, uterus and vagina).
The no effect level (NOEL) for this study is the high dose level of 500 mg/kg bw/day of the test article.
Applicant's summary and conclusion
- Conclusions:
- The results from the evaluation of reproductive organs, especially organ weights of ovary and testis and histopathology of gonads from this 28-day repeated dose study revealed no indications of any substance-related effects up to and including the highest test dose of 500 mg/kg bw/day.
- Executive summary:
In this Repeated Dose, 28-day Oral Toxicity Study performed comparable to OECD guideline 407, 12 May 1981 rMDEA-Esterquat C16-18 and C18 unsatd. (10 % a.i aqueous dispersion) was administered to groups of 25 Charles River CD rats male and female by oral gavage at dose levels of 1, 10 and 500 mg/kg bw/day for 28 days. Two other control groups received either deionised water or to pH 2.5 adjusted (HCL) deionised water (vehicle).
All animals survived to study termination. No test substance-related findings were detected or observed in clinical examinations, body weights, food consumption values, opthalmoscopic examinations, haematology, clinical biochemistry or clinical pathology evaluations including organ weights of ovary and testis and histopathology of reproductive organs (gonads, mammary gland (femals only), prostate and seminal vesicle, uterus and vagina).
The no effect level (NOEL) for this study is the high dose level of 500 mg/kg bw/day of the test article.
