- Executive summary:
OECD 420 (2017) - In an acute oral toxicity study, a group of fasted, 8-12 week old female Wistar rats were given a single oral dose of Reaction Mass of (4R)-4-isopropenyl-1-methylcyclohexene (limonene) and (4R)-4-(2-methoxypropan-2-yl)-1-methylcyclohexene (ether MT) at a single dose rate of 2000 mg/kg bw (limit test) and observed for 14 days.
In the absence of mortality during the observation period, the oral LD50 was estimated to be greater than 2000 mg/kg bw.
In addition, there were no treatment related clinical signs, necropsy findings or changes in body weight observed in any of the individuals.
Reaction Mass of (4R)-4-isopropenyl-1-methylcyclohexene (limonene) and (4R)-4-(2-methoxypropan-2-yl)-1-methylcyclohexene (ether MT) did not meet the criteria for classification according to Regulation (EC) No. 1272/2008 on the Classification, Labelling and Packaging of Substances and Mixture.

IN-LIFE DATES: From: 06 July 2017 To: 12 October 2017 - Route of administration:
- inhalation: aerosol
- Type of inhalation exposure:
- nose only
- Vehicle:
- clean air
- Mass median aerodynamic diameter (MMAD):
- 2.28 µm
- Geometric standard deviation (GSD):
- 1.58
- Remark on MMAD/GSD:
- The results of the particle size distribution should be viewed with caution and are included only as a guide to the aerosol/vapor ratio of the generated atmosphere, as the volatility of a test item will be over-emphasized by the high air velocities and low pressures within a cascade impactor.
- Details on inhalation exposure:
- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: Nose only exposure apparatus.
- Exposure chamber volume: The cylindrical exposure chamber had a volume of approximately 30 liters (dimensions: 28 cm diameter x 50 cm high).
- Method of holding animals in test chamber: During the exposure period, each rat was individually held in a tapered, polycarbonate restraining tube fitted onto a single tier of the exposure chamber and sealed by means of a rubber ‘O’ ring.
- Source and rate of air: Compressed air was supplied by means of an oil free compressor at a rate of 40 L /minute
- Method of conditioning air: Air was passed through a water trap and respiratory quality filters before it was introduced to the nebulizer.
- System of generating particulates/aerosols: Metal concentric jet nebulizer (Envigo CRS Limited, UK) located at the top of the exposure chamber.
- Method of particle size determination: The particle size of the generated atmosphere inside the exposure chamber was determined three times during the exposure period using a Marple Personal Cascade Impactor (Westech IS Ltd, Beds., UK). This device consisted of six impactor stages (10.4, 7.7, 4.1, 1.3, 0.90 and 0.56 μm cut points) with stainless steel collection substrates and a backup glass fiber filter, housed in an aluminum sampler. The sampler was temporarily sealed in a sampling port in the animals’ breathing zone and a suitable, known volume of exposure chamber air was drawn through it using a vacuum pump. The collection substrates and backup filter were weighed before and after sampling and the weight of test item, collected at each stage, calculated by difference. The mean amount for each stage was used to determine the cumulative amount below each cut-off point size. In this way, the proportion (%) of aerosol less than 10.4, 7.7, 4.1, 1.3, 0.90 and 0.56 μm was calculated. The resulting values were converted to probits and plotted against Log10 cut-point size. From this plot, the Mass Median Aerodynamic Diameter (MMAD) was determined (as the 50% point) and the geometric standard deviation was calculated. In addition the proportion (percentage) of aerosol less than 4 μm (considered to be the inhalable fraction) was determined. An impinger, set up as per atmosphere concentration determination was placed in series after the cascade impactor. Submission of these samples for chemical analysis allowed an estimate to be made of the amount of atmosphere present in the vapor phase. The sampling procedure involved 2 liters of test atmosphere being drawn through a glass impinger containing methanol (made up to 80mL). The samples were then submitted for chemical analysis.
- Treatment of exhaust air: The extract from the exposure chamber passed through a ‘scrubber’ trap and was connected with a high efficiency filter to a metered exhaust system.
- Temperature, humidity, pressure in air chamber: The temperature and relative humidity inside the exposure chamber were measured by an electronic thermometer/humidity meter (Hanna Instruments Ltd, Beds., UK) located in a vacant port in the animals’ breathing zone of the chamber and recorded every 30 minutes throughout the 4-Hour exposure period. Oxygen levels within the exposure chamber were measured by an electronic oxygen analyzer (Servomex (UK) Ltd, Crowborough, East Sussex) located in a port in the animals breathing zone during the 4 Hour exposure period.
TEST ATMOSPHERE
- Brief description of analytical method used: The test atmosphere was sampled nine times during the exposure period. The sampling procedure involved 2 liters of test atmosphere being drawn through a glass impinger containing methanol (made up to 80mL). The samples were then submitted for chemical analysis (HPLC) using an external standard technique.
- Samples taken from breathing zone: yes

- Preliminary study:
- During the characterization phase of the study, a group of two rats (one male, one female) were exposed to an atmosphere of the test item at a mean achieved atmosphere concentration of 1.82 mg/L for four hours. During exposure both animals exhibited decreased respiratory rate and wet fur. On removal from the chamber both animals decreased respiratory rate, hunched posture, pilo-erection, red/brown staining around the snout and wet fur. One hour post-exposure, decreased respiratory rate was no longer apparent. Both animals recovered to appear normal on Day 1 post-exposure.

- JUSTIFICATION FOR DATA WAIVING
In accordance with Annex VIII, Section 8.5.3, Column 2 of REACH, testing by the dermal route does not need to be conducted if:
- the substance does not meet the criteria for classification as acutely toxic 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) or, in the absence of an in vivo study by the oral route, no systemic effects after dermal exposure are predicted on the basis of non-testing approaches (e.g. read across, QSAR studies)
For this substance, no systemic effects were observed in the in vivo acute oral toxicity study (OECD 420), or in the LLNA study (OECD 429) where 100 % (w/w) solution was tested at the highest dose level.
