[Rationale for the Classification] Based on (1) to (3), it was classified in Category 1B, and effects on lactation were added. Besides, in (1), at a dose at which no general toxicity effects were observed in parental animals, reduced survival rate and subcutaneous hematoma/hemorrhage were observed in pups. In (2) and (3), it was suggested that this substance or a metabolite was transferred to pups via breast milk in the lactation period after birth and blood clotting disturbance occurred, causing hemorrhagic tendency, internal hemorrhaging, and death. [Evidence Data] (1) It was reported that, in a one-generation reproduction toxicity study with rats dosed by feeding, reduced survival rate and subcutaneous hematoma/hemorrhage were observed in pups at or above 90 mg/kg/day (EFSA (2019), AICIS IMAP (2015)). (2) In the two groups, one group in which female rats were dosed (6,250 ppm: 560 mg/kg/day) during the gestation period and also dosed similarly during the lactation period, and the other group in which female rats were dosed during the gestation period and then the pups born from the control group were fed diets containing this substance at 6,250 ppm, the increased mortality of F1 pups (67% and 77%) and the increased incidence of internal hemorrhaging (8% and 17%) were observed, compared to the group of pups born from and reared by dams which were fed control diets throughout the gestation and lactation periods, and the group of pups born from the treated group and reared by dams in the control group. In the pups of these groups, a decrease in the concentration of clotting factor X in blood was observed, and it was suggested that this substance or a metabolite transferred via milk impaired the vitamin K dependent clotting system in the pups, or decreased vitamin K in the breast milk, causing clotting disturbance in pups (EFSA (2019), AICIS IMAP (2015)). (3) In rats, medium-chain chlorinated paraffins (MCCPs) perturbed the clotting system in lactating neonates of treated mothers. The hemorrhagic effects in lactating neonates appeared as a result of persistent vitamin K deficiency, and the EFSA's expert panel concluded that this phenomenon was also relevant to humans (EFSA (2019)). [Reference Data, etc.] (4) It was reported that, in a prenatal development toxicity study (OECD TG 414, days 6-19 of gestation) with rats dosed by gavage, no developmental toxicity was observed (EFSA (2019), AICIS IMAP (2015)). (5) It was reported that, in a prenatal development toxicity study (OECD TG 414, days 6-27 of gestation) with rabbits dosed by gavage, no developmental toxicity was observed. (EFSA (2019), AICIS IMAP (2015)). (6) It was reported that, in a reproduction/developmental toxicity screening test (equivalent to OECD TG421, from 28 days before mating until day 21 of lactation) with rats dosed by feeding, no reproductive toxicity was observed (EFSA (2019), AICIS IMAP (2015)). (7) Medium-chain chlorinated paraffins (MCCPs) were detectable in 25 human milk samples of 18 women from London and Lancaster, the U.K. The values varied from 6.2 to 320 ng/g fat, with a median concentration of 21 ng/g fat and a 97.5th percentile of 130.9 ng/g fat, and no difference was seen between samples obtained from women in Lancaster or London (REACH registration dossier (Accessed May 2021)). (8) Detectable levels of this substance were found in one (61 ng/g fat) of 22 human milk samples collected anonymously (REACH registration dossier (Accessed May 2021)). (9) In the EU, it was classified in Lact. (Classification in CLP (Accessed May 2021)). |

H372 | P260 P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1) to (3), it was classified in Category 1 (kidney, thyroid). Besides, since the effects on the liver were considered to be adaptive drug responses, they were not adopted. [Evidence Data] (1) It was reported that, in a 90-day oral toxicity study with rats dosed by feeding, an increase in serum cholesterol and effects on the thyroid (reduced follicle sizes, tissue destruction, increased follicle height, nuclear vesiculation) were observed in females at 3.6 mg/kg/day (males, within the range for Category 1) and 4.2 mg/kg/day (females, within the range for Category 1); anisokaryosis and vesiculation of hepatocytes in males and females, effects on the thyroid (cytoplasmic vacuolation in males and females and reduced follicle sizes, tissue destruction, increased follicle height and nuclear vesiculation in males), and effects on the liver (an increase in relative liver weight, perivenous hepatocyte homogeneity), and inner medullary tubular dilation in females were observed at 36.2 mg/kg/day (males, within the range for Category 2) and 42.2 mg/kg/day (females, within the range for Category 2). However, it was reported that, since there was no test-based analysis and description on the liver, kidney, and thyroid, histopathological interpretation was not possible (EFSA (2019)). (2) It was reported that, in a 90-day oral toxicity study with rats dosed by feeding, chronic nephritis was observed in males and females at 10 mg/kg/day (males, within the range for Category 1); and increases in absolute and relative liver and kidney weight in males and females and an increase in serum cholesterol in females were observed at 100 mg/kg/day (within the range for Category 2) (EFSA (2019)). (3) It was reported that, in a 90-day oral toxicity study with rats dosed by feeding, increased hepatic UDPGT activity was observed in females at 100 ppm (9.3 mg/kg/day (males), 9.7 mg/kg/day (females), within the range for Category 1); and a decrease in plasma FT3 levels in males and an increase in plasma TSH levels and thyroiditis in females were observed at 300 ppm (23 mg/kg/day (males), 24.6 mg/kg/day (females), within the range for Category 2) (EFSA (2019), AICIS IMAP (2015), REACH registration dossier (Accessed May 2021)). |
