Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Details on oral exposure:
- Dose level (volume): 2000 mg/kg (10 mL/kg) body weight
- Doses:
- Single dose: 2000 mg/kg b.w.
- No. of animals per sex per dose:
- 3
- Control animals:
- no
- Details on study design:
- The toxicity of the test substance was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 2000 mg/kg. The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the
guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the time interval between the
dose groups.
Observations:
Mortality/Viability Twice daily.
Body weights Days 1 (pre-administration), 8 and 15).
Clinical signs At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15. The symptoms were graded according to fixed scales and the time of onset, degree and duration were recorded:
Maximum grade 4: grading slight (1) to very severe (4)
Maximum grade 3: grading slight (1) to severe (3)
Maximum grade 1: presence is scored (1).
Necropsy At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy.
Descriptions of all internal macroscopic abnormalities were recorded.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The oral LD50 value of b-NADP, Disodium salt in Wistar rats was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, b-NADP, Disodium salt does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the:
- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2007),
- Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures. - Executive summary:
Assessment of acute oral toxicity with b-NADP, Disodium salt in the rat (Acute Toxic Class Method).
The study was carried out based on the guidelines described in: OECD No.423 (2001) "Acute Oral Toxicity, Acute Toxic Class Method"
b-NADP, Disodium salt was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15).
No mortality occurred.
Hunched posture was observed for three females on Day 1.
The body weight gain shown by the animals over the study period was considered to be normal.
No macroscopic abnormalities were noted.
The oral LD50value of b-NADP, Disodium salt in Wistar rats was established to exceed 2000 mg/kg body weight.
