DETAILS OF FOOD AND WATER QUALITY:
The food used in the study was assayed for chemical and microbial contaminants. Fed. Reg. Vol. 44, No. 91 (09 May 1979), p 27354 (EPA), served as the guideline for maximum tolerable contaminants. Additionally, the levels of
phytoestrogens should not exceed 350 μg of genistein equivalents/gram. According to recommendations of the GVSOLAS, the total amount of bacteria must not exceed 1*10^5 per g food.
The drinking water is regularly assayed for chemical contaminants both by the municipal authorities of Frankenthal and by the Environmental Analytics Water/Steam Monitoring Department of BASF SE as weil as for bacteria by a contract laboratory. The Drinking Water Regulation will serve as the guideline for maximum tolerable contaminants.

Additional information
Maternal toxicity (14 days), rat, RL2
A 14-day prenatal range-finding toxicity study with pregnant animals similar to an OECD 414 study has been conducted previous to an OECD 422 study. The test item was administered orally by repeated gavage to female Wistar rats from gestation day (GD) 6 through GD 19 to facilitate the selection of the dose levels for the subsequent definite study. Doses of 0, 300 and 1000 mg/kg bw in deionized water were given to seven animals per dose. For this purpose, disposable syringes of suitable size and suitable gavage tubes were used. During the study, all animals were observed for any clinically abnormal signs and food and water consumption and body weights were recorded. On GD 20, blood samples were obtained from all surviving animals by retrobular venous puncture. After blood sampling, all dams were sacrificed and assessed by gross pathology. Hematological parameters were examined as well as clinical chemistry and organ weights. The fetuses were not investigated. The administration of the test item by gavage to pregnant female Wistar rats from GD 6-19 caused no substance related findings up to a dose of 1000 mg/kg body weight/day except slightly increased absolute/relative liver weights. Thus, the NOAEL was found to be ≥1000 mg/kg bw (BASF 2020).
Justification for classification or non-classification
The available experimental test data are reliable but not sufficient for classification purposes under Regulation (EC) No 1272/2008, as amended for fifteenth time in Regulation (EU) No 2020/217.
