Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- Species: Rat, Wistar strain Crl:WI (Han) (outbred, SPF-Quality). Recognized by international guidelines as the recommended test system (e.g. OECD, EC).
Source: Charles River Deutschland, Sulzfeld, Germany.
Number of animals: 6 Females (nulliparous and non-pregnant).
Age and body weight: Young adult animals (approx. 10 weeks old) were selected. Body weight variation did not exceed +/- 20% of the sex mean.
Identification: Earmark.
Conditions: Animals were housed in a controlled environment, in which optimal conditions were considered to be approximately 15 air changes per hour, a temperature of 21.0 ± 3.0ºC (actual range: 20.3 – 22.0ºC), a relative humidity of 40-70% (actual range: 31 - 53%) and 12 hours artificial fluorescent light and 12 hours darkness per day.
Accommodation: Group housing of 3 animals per cage in labeled Macrolon cages (MIV type; height 18 cm.) containing sterilized sawdust as bedding material and paper as cage-enrichment.
Acclimatization period was at least 5 days before start of treatment under laboratory conditions.
Diet: Free access to pelleted rodent diet.
Water: Free access to tap water.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: A mixture of Ethyl acetate:Corn oil of 1:3 (w/w)
- Details on oral exposure:
- VEHICLE: A mixture of Ethyl acetate : Corn oil of 1:3 (w/w) was used as suitable vehicle. The calculated s.g. is 0.915.
- Amount of vehicle (if gavage): 10 mL/kg
- 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: 10 mL/kg
DOSAGE PREPARATION (if unusual): The formulations (w/w) were prepared within 4 hours prior to dosing. Homogeneity was accomplished to a visually acceptable level. Adjustment was made for specific gravity of the vehicle.
Animals were deprived of food overnight prior to dosing and until 3-4 hours after administration of the test substance. Water was available. - Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- two subsequent groups of 3 females received 2000 mg/kg
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
mortality/viability: twice daily
clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15.
Body weight: on Day 1 (predose) and days 8 and 15
- Necropsy of survivors performed: yes
Dosing days: first 3 animals: 26 january 2010, second 3 animals 28 january 2010 - Statistics:
- not applicable
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Hunched posture was seen in three females on Day 1. The staining properties of the test substance caused the faeces and some skin parts to turn purple.
- Other findings:
- No abnormalities were found at macroscopic post mortem examination of the animals.
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The oral LD50 value of Custom Red #3 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, Custom Red #3 does not have to be classified and has no obligatory labeling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) of the United Nations (2007) and Regulation (EC) No 1272/2008 on classification, labeling and packaging of substances and mixtures.
