Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- The animals of the treated group received an effective dose of 2000 mg/kg body weight of test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA-TERPINENES, TERPINOLENE.
In the first and the second step of the study, the test item was administered by gavage under a volume of 2.36 mL/kg body weight (corresponding to 2000 mg/kg according to the density of 0.846 g/mL supplied by the Sponsor) using a suitable graduated syringe fitted with an oesophageal metal canula - Doses:
- 2000 mg/kg corresponding to 2.36 mL/ kg bw
- No. of animals per sex per dose:
- 6 (3 per step)
- Control animals:
- other: historical data
- Details on study design:
- Clinical observations and mortality were recorded every day for 14 days
Animals were weighed on day D0 (just before administering the test item) then on D2, D7, and D14.
On D14, the animals were anaesthetised with sodium pentobarbital and administration continued to fatal levels. Macroscopic observations were entered on individual autopsy sheets.
Only those organs likely to be modified in cases of acute toxicity were examined. No organ was removed and preserved in view to microscopic examinations. - Statistics:
- none
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50 cut-off
- Effect level:
- 2 500 mg/kg bw
- Based on:
- test mat.
- Mortality:
- Two mortalities were noted in the animals treated at the dose of 2000 mg/kg body weight, one at 48 hours post dose during the first step of the study and a one at 24 hours post dose during the second step of the study.
- Clinical signs:
- The mortalities were preceded by a decrease in spontaneous activity (2/2). No others clinical signs were noted. In the surviving animals (4/6), a decrease in spontaneous activity (4/4) was noted during the first hours of the test. The animals recovered a normal activity at 3-hour post dose. No others signs of systemic toxicity were noted.
- Body weight:
- The body weight evolution of the animals remained normal throughout the study.
- Gross pathology:
- The macroscopic examination of this animal at the end of the study did not reveal any treatment related changes.
Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The LD50 of test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA-TERPINENES, TERPINOLENE is higher than 2000 mg/kg body weight by oral route in the rat. In accordance with OECD Guideline No. 423, the LD50 cut-off of the test item may be considered as 2500 mg/kg body weight by oral route in the rat.
According to the criteria for classification, packaging and labelling of dangerous substances and preparations in accordance with Regulation EC No. 1272/2008, test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA-TERPINENES, TERPINOLENE does not have to be classified.
According to GHS regulation, test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA- TERPINENES, TERPINOLENE is classified in category 5. Hazard statement H303 (may be harmful if swallowed) and signal word Attention are required. - Executive summary:
REACTION MASS OF DL-LIMONENE, ALPHA-GAMMA-TERPINENES, TERPINOLENE was administered to a group of 6 female Sprague Dawley rats at the dose of 2000 mg/kg body weight. The experimental protocol was established according to the official method as defined in OECD Guideline No. 423 dated December 17th, 2001 and test method B.1tris of Council regulation No. 440/2008.
Two mortalities were noted in the animals treated at the dose of 2000 mg/kg body weight, one at 48 hours post dose during the first step of the study and one at 24 hours post dose during the second step of the study. The mortalities were preceded by a decrease in spontaneous activity (2/2). No other clinical signs were noted. Rigor mortis was noted before the necropsy (2/2).The macroscopic examination of the animals revealed a thinning of forestomach and corpus with red spots (1/2).
In the surviving animals (4/6), a decrease in spontaneous activity (4/4) was noted during the first hours of the test. The animals recovered a normal activity at a 3-hour post dose. No others signs of systemic toxicity were noted. The macroscopic examination of this animal at the end of the study did not reveal any treatment related changes.
In conclusion, the LD50 of test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA-TERPINENES, TERPINOLENE is higher than 2000 mg/kg body weight by oral route in the rat. In accordance with OECD Guideline No. 423, the LD50 cut-off of the test item may be considered as 2500 mg/kg body weight by oral route in the rat.
According to the criteria for classification, packaging and labelling of dangerous substances and preparations in accordance with Regulation EC No. 1272/2008, test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA-TERPINENES, TERPINOLENE does not have to be classified.
No signal word or hazard statement is required.
According to GHS regulation, test item REACTION MASS OF DL-LIMONENE, ALPHA- GAMMA- TERPINENES, TERPINOLENE is classified in category 5. Hazard statement H303 (may be harmful if swallowed) and signal word Attention are required.
