Study period:: From January 22, 2008 to May 07, 2008
Reliability:: 1 (reliable without restriction)
Rationale for reliability incl. deficiencies:: guideline study
Qualifier:: according to guideline
Guideline:: OECD Guideline 423 (Acute Oral toxicity - Acute Toxic Class Method)
Qualifier:: according to guideline
Guideline:: EU Method B.1 tris (Acute Oral Toxicity - Acute Toxic Class Method)
Qualifier:: according to guideline
Guideline:: EPA OPPTS 870.1100 (Acute Oral Toxicity)
Principles of method if other than guideline:: - Japanese Ministry of Agriculture, Forestry and Fisheries
(JMAFF), 12 Nousan, Notification No 8147, November 2000,
including the most recent partial revisions.
GLP compliance:: yes
Test type:: acute toxic class method
Species:: rat
Strain:: Wistar
Remarks:: Crl:WI (Han)
Sex:: female
Details on test animals or test system and environmental conditions:: - Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: about 9 week old
- Housing: three animals per cage
- Water: ad libitum
- Acclimation period: at least 5 days
- Temperature (°C): 21 ± 3 °C
- Humidity (%): 30-70 %
- Photoperiod (hrs dark / hrs light): 12-hrs dark / 12-hrs light cycle
Route of administration:: oral: gavage
Vehicle:: water
Doses:: 2000 mg/kg body weight
No. of animals per sex per dose:: three females for each dose group
Sex:: female
Dose descriptor:: LD50
Effect level:: > 2 000 mg/kg bw
Based on:: test mat.
Interpretation of results:: GHS criteria not met
Conclusions:: According to OECD 423 test method, the LD50 cut-off value of Everzol Red CDN Crude was greater than 5000 mg/kg B.W.. Therefore, Everzol Red CDN Crude was Category 5 based on GHS criteria.
Executive summary:: This test using the procedures outlined in the NOTOX Study Plan for 487476.Everzol Red CDN Crude was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight. All animals were noted that hunched posture and/or piloerection on Day 1 and red faeces on Day 2. The body weight gain of all rats over the study period were considered to be similar to that expected of normal untreated animals of the same age and strain. No mortality occurred. No abnormalities were found at macroscopic post mortem examination of the animals. Therefore, the oral LD50 value of Everzol Red CDN Crude in Wistar rats was established to exceed 2000 mg/kg body weight.

Additional information

Acute toxicity: via oral route

Everzol Red CDN Crude was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight. All animals were noted that hunched posture and/or piloerection on Day 1 and red faeces on Day 2. The body weight gain of all rats over the study period were considered to be similar to that expected of normal untreated animals of the same age and strain. No mortality occurred. No abnormalities were found at macroscopic post mortem examination of the animals. Therefore, the oral LD50 value of Everzol Red CDN Crude in Wistar rats was established to exceed 2000 mg/kg body weight.
