Applicant's summary and conclusion
- Conclusions:
- This study revealed no maternal toxicity at any dose and no reproductive, breeding or developmental toxicity at any dose from two weeks prior to mating to at least 3 days of lactation (females). Therefore, a NOAEL for maternal local and systemic toxicity of 1000 mg/kg bw/d (equivalent to 90 mg/kg/d Al3+) was established. For reproductive and developmental toxicity the NOAEL was 1000 mg/kg bw /d (equivalent to 90 mg/kg/d Al3+).
- Executive summary:
A combined repeated dose / reproductive screening study (OECD 422), studied the administration of Aluminium chloride basic by oral gavage to male and female Wistar rats at dose levels of 40, 200 or 1000 mg /kg/day (equivalent to 3.6, 18 or 90 mg/kg/day Al3 +). 10 animals/sex/group were used. Males were exposed for 28 days, females between 37 -53 days, i.e. during 2 weeks prior to mating, during mating, during postcoitum, and during at least 3 days of lactation. Litter was not exposed.
There were no treatment-related effects found regarding to mortality, clinical signs, functional observations, histopathology, organ weigths, reproduction, breeding data and pup development. No reproduction, breeding and developmental toxicity was observed for treatment up to 1000 mg/kg/day (equivalent to 90 mg/kg/day Al3+).
Based on these results, the No Observed Adverse Effect Level for maternal and developmental toxicity was established to be 1000 mg/kg bw/day for Aluminium chloride basic (equivalent to 90 mg/kg/day Al3+)
In a combined repeated dose / reproductive screening study, administration of Aluminium chloride basic by oral gavage to male and female rats at dose levels of 20, 200 or 1000 mg /kg/d,
From two weeks prior to mating to at least 3 days of lactation (females) or 28 days (males) revealed no maternal toxicity at any dose and no reproductive, breeding or developmental toxicity at any dose.
The NOAEL for paternal systemic toxicity is 1000 mg/kg bw/d (equivalent to 90 mg/kg/d Al3+).
The NOAEL for maternal local and systemic toxicity is 1000 mg/kg bw/d (equivalent to 90 mg/kg/d Al3+).
The NOAEL for reproductive and developental toxicity is 1000 mg/kg bw /d (equivalent to 90 mg/kg/d Al3+)
