Effects on fertility

Description of key information

Data waiving (study scientifically not necessary / other information available): A screening reproduction / developmental study does not need to be conducted because a pre-natal developmental toxicity study is available.

Data waiving (study scientifically not necessary / other information available): In accordance with column 1 of REACH Annex IX, a two-generation reproductive toxicity study does not need to be conducted since the repeated dose toxicity study does not indicate adverse effects on reproductive organs or tissues.

Effects on developmental toxicity

Description of key information
Key study: Read-across from experimental data on an analogue. Test method OECD Guideline 414. GLP study. The NOEL for both maternal and developmental toxicity by oral route in rats was determined to be 1000 mg/kg/day since no effects were observed at the highest dose tested.

Key result
Developmental effects observed:
no
Conclusions:
Based on the read-across approach, the NOEL for pre-natal developmental toxity by oral route in rats was determined to be 1000 mg/kg bw/day.
Executive summary:

Based on experimental results obtained in a study according to OECD 414 on the analogue substance FB220 where the test item did not produce developmental and/or maternal toxicity, the read-across approach is applied and the NOEL for pre-natal developmental toxity by oral route in rats for the subtance P-1401 was determined to be 1000 mg/kg bw/day.

Effect on developmental toxicity: via oral route
Endpoint conclusion:
no adverse effect observed
Dose descriptor:
NOAEL
1 000 mg/kg bw/day
Study duration:
subacute
Species:
rat
Quality of whole database:
The study is GLP compliant and of high quality (Klimisch score = 1). Since read-across approach was applied the Klimisch score is = 2.
Effect on developmental toxicity: via inhalation route
Endpoint conclusion:
no study available
Effect on developmental toxicity: via dermal route
Endpoint conclusion:
no study available
Additional information

Key study: Read-across approach from experimental data on the analogue substance CAS 16470-24-9:

A pre-natal developmental toxicity test was performed on the analogue substance CAS 16470-24-9 according to OPPTS Guideline 870.3700, equivalent to OECD Guideline 414 (GLP study). Dose levels up to1000 mg/kg/day were administered via oral gavage daily from Days 6 through 19 of gestation at a volume of 10 mL/kg. The females were time mated upon delivery. Litters were delivered by cesarean section an Day 20 of gestation. All findings were either comparable with the concurrent vehicle control and/or historical control incidences. The No Observed Effect Level (NOEL) for both maternal and developmental toxicity was 1000 mg/kg/day. The substance was determined to be not teratogenic in rats following oral administration of dose up to and including 1000 mg/kg-bw/day.

Justification for classification or non-classification

Based on available data, the substance is not classified for developmental toxicity according to CLP Regulation (EC) No. 1272/2008.
