Name:aqua purificata
Batch number: 190101
Date of expiration:07.07.2019
Produced by: Magilab Kft.
Formulation: All doses were formulated in the vehicle (distilled water). The vehicle was selected based on trial preparations performed at the testing facility and on test item data supplied by the sponsor. The concentration of the 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 was taken into consideration in the course of the making of solution.
MAXIMUM DOSE VOLUME APPLIED: 10 ml/kg
Justification of the doses
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 absence or presence of mortality of animals doses at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration an severity of the signs of toxicity were taken into account for determination of the time interval between the dose groups. 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 body weight
- No. of animals per sex per dose:
- 3 females per dose (first step)
3 females per dose (second step) - Control animals:
- no
- Details on study design:
- Procedure: A single oral administration - followed by a fourteen-day observation period - was performed by gavage, using plastic feeding tubes. The day before treatment the animals were fasted. The food but not water was withheld overnight. Animals were weighed before the application and the appropriate volume will be applied accordingly. T he food was given back 3 hours after the treatment. The first group was observed for up to min. 24 hours before the next step was treated.
Mortality: 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.
General state, external appearance, behavior and clinical symptoms: 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 once each day for 14 days thereafter. Individual observations were performed on the skin and fur, eyes and mucous membranes and also respiratory, circulatory, autonomic and central nervous system, somatomotor activity and behaviour pattern. Particular attention was directed to observation of tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma.
Measurement of Body Weight: 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 rats were sacrificed under isofluran anaesthesia and subjected to necropsy. After examination of the external appearance, the cranial, thoracic and abdominal cavities were opened and the appearance of the tissues and organs was observed, and any abnormality was recorded with details of its location, colour, shape and size. - Statistics:
- No statistical analysis was performed.

- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- No death occurred at 2000 mg/kg bw single oral dose of 5-(Hydroxymethyl)furfural. All female rats in step 1 and step 2 survived until the end of the 14-day observation period.
- Clinical signs:
- other: In group 1 treated with 2000 mg/kgbw dose clinical sign of reaction comprised of decreased activity (6 cases of 57 observations), closed eyes (2/57) and piloerection (2/57). Decreased activity (score -1) was observed in all animals. Closed
- Gross pathology:
- All animals survived until the scheduled necropsy on Day 15. Moderate hydrometra was observed in female No.: 4780 of group 1 in animal No.: 4789 of group 2, as well severe hydrometra was detected in animal No.: 4791 of group 2. Hydrometra is physiological finding and connected to the oestrus cycle of the animal. Nopathological changes were found related to the effect of the test item during the macroscopic examination of animals treated with 2000 mg/kg bw dose.
- Other findings:
- No death occurred after the single 2000 mg/kg bw oral dose of 5-(Hydroxymethyl)furfural. The clinical signs observed in both groups were related to the effect of the test item. There were no any related to the effect of the test item found in body weights and body weight gains during the study. Autopsy revealed no treatment related pathological changes.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The method used, was not intended for the precise calculation of a precise LD50 value. The oral LD50 value of the test item in Wistar rats was established to exceed 2000 mg/kg body weight.The test item was ranked into classes of Globally Harmonized Classification System (GHS) described in the OECD Guideline No. 423 as below:
Dose (mg/kg bw): 2000
Mortality(dead/treated): 0/6
LD50 (mg/kg bw): = 5 000
GHScategory: 5 or unclassified
In conclusion, the LD50 of the test item 5-(Hydroxymethyl)furfural is higher than 5000 mg/kg bodyweight by oral route in the rat. Based on these results, the test item 5-(Hydroxymethyl)furfural 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 (2017) (including all amendment) and regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments). - Executive summary:
General information:
The goal of this study was to assess the acute oral toxicity with 5-(Hydroxymethyl)furfural in the Wistar rat (following the Acute Toxic Class Method).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, administered by oral gavage. 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 (presented in Appendix VII) was met. Animals were weighed, observed for lethality and toxic symptoms for 14 days after the treatment. Gross pathological examination was carried out on the 15th day after the treatment in animals.
Lethality, Clinical symptoms and Body weight:
No death occurred at 2000 mg/kg bw single oral dose of 5-(Hydroxymethyl)furfural. All female rats in step 1 and step 2 survived until the end of the 14-day observation period. In a first step, CNS - and emotion symptoms (decreased activity, closed eyes) anddisturbance of autonomic functions (piloerection) were observed in animals on the treatment day between 30 minutes and 1 hour after the treatment. In a second step, CNS - and emotion symptoms (decreased activity, closed eyes, bedding chewing), disturbances of coordination (abnormal gait, incoordination), decreased righting reflex and disturbances of autonomic functions (diuresis, piloerection) were observed in animals on the treatment day between 1 and 4 hours after the treatment. The body weight development was undisturbed in all animals.
Gross pathology:
All organs of the animals treated with 2000 mg/kg bw proved to be free of treatment related gross pathological changes.
Evaluation:
The method used is not intended to allow the calculation of a precise LD50 value. The oral LD50 value of the test item in Wistar rats was established to exceed 2000 mg/kg body weight. The test item was ranked into classes of Globally Harmonized Classification System (GHS) described in the OECD Guideline No. 423 as below:
Dose (mg/kg bw): 2000
Mortality(dead/treated): 0/6
LD50 (mg/kg bw): = 5 000
GHScategory: 5 or unclassified
In conclusion, the LD50 of the test item 5- (Hydroxymethyl)furfural is higher than 5000 mg/kg bodyweight by oral route in the rat.Based on these results, the test item 5-(Hydroxymethyl)furfural 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 (2017) (including all amendment) and regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).
