- Details on oral exposure:
- MAXIMUM DOSE VOLUME APPLIED: The dose volume for each animal was based on the body weight measurement prior to dosing. Dose volume (mL/kg body weight) was calculated as follows: Dose level (g/kg) / spec.gravity or density (g/mL).
The maximum dose level applied was 2000 mg/kg bodyweight. - Doses:
- 2000 mg/kg (10 mL/kg) body weight
The study was conducted in a stepwise manner with two groups of 3 females. The first group was treated at a dose level of 2000 mg/kg bw. Based on the results, one additional group was dosed at 2000 mg/kg bw. - No. of animals per sex per dose:
- 6 females/dose (2 groups of three females in a stepwise manner)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: twice daily;
Body weights: on the day of dosing (fasted weight) and on days 1 (pre-dosing), 8 and 15;
Clinical signs: at periodic intervals (at least three times) on the day of dosing (day 1) and once daily thereafter
- Necropsy of survivors performed: yes
- Other examinations performed: no - Statistics:
- The LD50 cut-off value was established based on OECD guideline 423. No statistical analysis was performed (the method used is not intended to allow the calculation of a precise LD50 value).
- Key result
- Sex:
- female
- Dose descriptor:
- LD0
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Hunched posture, uncoordinated movements and/or piloerection were noted on Days 1 and/or 2.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an acute oral toxicity study with rats, performed according to OECD guideline 423 and GLP principles, the LD50 for Tricyclodecanemonomethylol acrylate was established to exceed 2000 mg/kg bw. Based on the result obtained in this study, SR789 does not need to be classified for acute toxicity under GHS and under Regulation (EC) 1272/2008.
- Executive summary:
The objective of this study was to determine the potential toxicity of Tricyclodecanemonomethylol acrylate, when given by oral gavage at a single dose to rats of a single sex at one or more defined doses to evaluate the potential reversibility of any findings (TG OECD 423). Tricyclodecanemonomethylol acrylate was administered by oral gavage to two consecutive groups of three female Wistar rats at 2000 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15).
No mortality occurred. Hunched posture, uncoordinated movements and/or piloerection were noted on Days 1 and/or 2. The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of the animals.
The oral LD50 value of Tricyclodecanemonomethylol acrylate in Wistar rats was established to exceed 2000 mg/kg body weight.

Additional information
Oral acute toxicity study (van Sas 2018):
Test substance was administered by oral gavage to two consecutive groups of three female Wistar rats at 2000 mg/kg body weight according to the Test Guideline n°423. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15).
No mortality occurred. Hunched posture, uncoordinated movements and/or piloerection were noted on Days 1 and/or 2. The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of the animals.
The oral LD50 value of Tricyclodecanemonomethylol acrylate in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for classification or non-classification
Based on the available data, no classification for acute toxicity is required for Tricyclodecanemonomethylol acrylate according to the Regulation EC N°1272/2008.
