DOSAGE PREPARATION: The test material was freshly formulated at a concentration of 200 mg/mL in the vehicle, in the Pharmacy of Citoxlab Hungary Ltd. on the day of administration. The formulation container was stirred continuously up to finishing the treatment.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: Initially, three females (assigned to Group 1) were treated at a dose level of 2000 mg/kg body weight (bw). The test material did not cause mortality in this group therefore a confirmatory group (Group 2) was treated at the same dose level. The test material did not cause mortality in the confirmatory group, so no further testing was required according to OECD 423 and Commission Regulation (EC) No 440/2008 of 30 May 2008, B.1.tris. - Doses:
- Single oral gavage dose of 2000 mg/Kg bw
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Clinical observations were performed at 30 minutes, 1, 2, 3, 4 and 6 hours after dosing and daily for 14 days thereafter. Body weight was measured on Days -1, 0 and 7 and Day 14.
- Necropsy of survivors performed: yes, All animals were subjected to a necropsy and a macroscopic examination.
- Other examinations performed: clinical signs (Individual observations were performed on the skin, fur, eyes, mucous membranes, 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.), body weight - Statistics:
- The method used was not intended to allow the calculation of a precise LD50 value.
The test material was ranked into categories of Globally Harmonized Classification System (GHS (rev. 7) 2017).
Clinical signs, body weight, body weight gain and gross macroscopic data were tabulated.
Results and discussion
- Preliminary study:
- Initially, three females (assigned to Group 1) were treated at a dose level of 2000 mg/kg body weight (bw). The test material did not cause mortality in this group therefore
a confirmatory group (Group 2) was treated at the same dose level.

Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- Under the conditions of this study, the acute oral LD50 value for the test material was determined to be >2000 mg/Kg bw in female Crl:WI rats.
According to the GHS criteria, the test material (Reaction mass of dipentene and (Z)-3,7-dimethylocta-1,3,6,-triene]) can be ranked as "Category 5" or “Unclassified” for acute
oral exposure. - Executive summary:
In a key study, the single-dose oral toxicity of the test material (Reaction mass of dipentene and (Z)-3,7-dimethylocta-1,3,6,-triene) was evaluated in Crl:WI rats according to the acute toxic class method (OECD Guideline 423).
Initially, three females (assigned to Group 1) were treated at a dose level of 2000 mg/Kg bw. The test material did not cause mortality in this group, therefore a confirmatory group (Group 2) was treated at the same dose level. The test material did not cause mortality in the confirmatory group, so no further testing was required as per Guideline recommendations.
A single oral treatment was carried out by gavage for each animal after an overnight food withdrawal. Food was made available again 3 hours after the treatment. The test material was administered formulated in propylene glycol with 1% polysorbate 80 at a concentration of 200 mg/mL at a dose volume of 10 mL/kg bw.
Clinical observations were performed at 30 minutes, 1, 2, 3, 4 and 6 hours after dosing anddaily for 14 days thereafter. Body weight was measured on Days -1, 0 and 7 and Day 14. All animals were subjected to a necropsy and a macroscopic examination.
No mortality was observed through the study period and there was no evidence of clinical toxicity subsequent to treatment at 2000 mg/Kg bw. Normal body weight gain was observed in the observation period. However, one animal exhibited slight body weight loss between Day 7 and Day 14. As normal body weight changes were observed from Day 0 up to Day 7, and no other animal showed a similar trend between Day 7 up to Day 14, this change was considered incidental and minimal and not treatment-related.Focal thickness of the non-glandular stomach mucosa was observed in 3 out of 6 animals exposed to the test material.
Under the conditions of this study, the acute oral LD50value for the test material was determined to be >2000 mg/Kg bw in female Crl:WI rats.
According to the GHS criteria, the test material (Reaction mass of dipentene and (Z)-3,7-dimethylocta-1,3,6,-triene]) can be ranked as "Category 5" or “Unclassified” for acute oral exposure.
