Administration / exposure
- Route of administration:
- oral: gavage
- Details on oral exposure:
- GAVAGE METHOD: Plastic feeding tubes.
Frequency: Single dosage, on Day 1.
VEHICLE Polyethylene glycol 400 (Merck, Darmstadt, Germany) (specific gravity 1.125).
- Justification for choice of vehicle: The vehicle was selected based on trial formulations performed at NOTOX and on test substance data supplied by the sponsor.
MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg (10 mL/kg) bw.
DOSAGE PREPARATION:
The formulations (w/w) were prepared using amber coloured glassware within 4 h prior to dosing. Homogeneity was accomplished to a visually acceptable level. Adjustment was made for specific gravity of the test substance and vehicle. No correction was made for purity of the test substance. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6 (2 groups of three females in a stepwise manner)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 d
- Frequency of observations and weighing:
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.
- Necropsy of survivors performed: 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.
- Other examinations performed: none. - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).

Applicant's summary and conclusion
- Interpretation of results:
- other: EU CLP criteria not met
- Conclusions:
- Under the study conditions, the oral LD50 value of the test substance in rats was considered to be > 2,000 mg/kg bw.
- Executive summary:
A study was conducted to determine the acute oral toxicity of test substance, DPHA according to OECD Guideline 423, EU method B.1 tris, EPA OPPTS 870.1100 and Japanese Ministry of Agriculture, Forestry and Fisheries (JMAFF) Guidelines, in compliance with GLP. The test substance was administered by oral gavage to two groups of three female Wistar rats at 2,000 mg/kg bw. No mortality occurred. Hunched posture and/or piloerection were noted in all animals on Day 1. The body weight gain shown over the study period was similar to that expected of normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post-mortem examination. Under the study conditions, the oral LD50 value of the test substance in rats was considered to be > 2,000 mg/kg bw (Beerens-Heijnen, 2012).
