Description of key information

Repeated dose toxicity: Oral

Data available for the test chemical was reviewed to determine the toxic nature of the target chemical. The studies are as mentioned below:

Combined Repeated Dose Toxicity Study with the Reproduction/ Developmental Toxicity Screening Test (OECD TG422) was performed to evaluate the toxic nature of the test chemical upon repeated dosing by oral route. The test was performed onmale and female Crl:CD (SD) rats at dose levels of 0, 80, 200, 500 mg/kg/day. The animals were observed for clinical signs, body weight, food consumption, urinalysis, hematological and blood biochemistry parameters, gross and histopathological changes. On the basis of observations made, the No Observed Adverse effect level (NOAEL) for the test chemical is considered to be 80 mg/Kg bw/day in male and femaleCrl:CD (SD) rats.

Repeated dose toxicity: Inhalation

The repeated inhalation toxicity study need not be conducted because exposure to humans via inhalation route is not likely taking into account the low vapour pressure of the test chemical, which is reported to be 1.12E-08 Pa. Thus, exposure to inhalable dust, mist and vapour of the chemical is highly unlikely. Therefore this study is considered for waiver.  

Repeated dose toxicity: Dermal

The acute dermal toxicity value for1-(3-Chlorophenyl)-4-(3-chloropropyl)-piperazine (CAS no 52605-52-4)(as provided in section 7.2.3) is >2000 mg/kg body weight. Considering this, the end point for repeated dermal toxicity is considered as waiver

Based on the observations made, the test chemical is not likely to be toxic upon repeated exposure by oral, dermal and inhalation route of exposure as per the criteria mentioned in CLP regulation.
