Animals received ssniff® SM R/M-Z+H complete diet for rats and mice produced by ssniff Spezialdiäten GmbH, D-59494 Soest Germany
and tap water from municipal supply, as for human consumption from bottle ad libitum. - Route of administration:
- oral: gavage
- Vehicle:
- water
- Remarks:
- Aqua purificata Ph.Hg. VIII.
- Details on oral exposure:
- All doses were formulated in the vehicle. Concentration of formulations was adjusted to maintain a treatment volume of 10 mL/kg bw. The test item was applied in a concentration of 200 mg/mL. The correction factor (1.14) was taken into consideration in the course of the making of solution. Formulations were prepared just before the administration and were stirred continuously during the treatment.
Vehicle:
Name: Aqua purificata Ph.Hg. VIII.
Batch number: 1608-5511
Date of expiration: 11.02.2017
Produced by: Parma Produkt Kft.
The acute toxic class method was carried out involving a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats. The dose refers to the dye content (88 %, correction factor of 1.14) and corresponds to 2280 mg product/kg bw. No animal died in the first step at 2000 mg/kg bw dose level, so treatment with 2000 mg/kg bw was repeated on further three female rats. No animal died in the second step, too, so the test was finished, the stopping criteria of Annex 2d of OECD Guideline No. 423 was met. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6 females/dose (3 females/step)
- Control animals:
- no
- Details on study design:
- Duration of observation period after the treatment: 14 days.
Frequency of observations:
Animals were observed individually after dosing at least once during the first 30 minutes, then 1 h, 2 h, 3 h, 4 h after the treatment and twice each
day for 14 days thereafter.
Body weight measurement:
The body weights were recorded on day 0 (just before the treatment), on day 7 and on day 15 with a precision of 1 g.
Necropsy:
At the end of the observation period all surviving rats were necropsied. - Statistics:
- No statistics was used in the study.
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- act. ingr.
- Mortality:
- No lethality was noted at a single oral dose of 2000 mg/kg bw.
- Clinical signs:
- No treatment related symptoms were observed throughout the 14-day post-treatment period.
- Body weight:
- The mean body weight of animals treated with 2000 mg/kg bw dose corresponded to their species and age throughout the study.
- Gross pathology:
- No pathological changes were found related to the treatment with the test item during the macroscopic examination of animals treated with 2000 mg/kg bw dose.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral LD50 was determined to be > 2000 mg dye/kg bw (corresponding to > 2280 mg test item/kg bw).
- Executive summary:
An acute oral toxicity study was performed according to OECD guideline 423. The acute toxic class method was carried out involving a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats.

Acute inhalation toxicity:
The study does not need to be conducted as exposure of humans via inhalation is not the appropriate route of exposure. Furthermore, physicochemical and toxicological properties do not suggest a potential for a significant rate of respiratory absorption.
Acute dermal toxicity:
According to REACH Annex VIII point 8.5.3 the study does not need to be conducted because the substance does not meet the criteria for classification as acute toxicity or STOT SE by the oral route and no systemic effects have been observed in in vivo studies with dermal exposure (e.g. skin irritation, skin sensitisation).
