(Also known as: refined vegetable oil; oilseed rape extract)
SUMMARY
Hazard alerts
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Supplied as an oil formulation
Commercial production
Canola oil production involves transforming canola seeds into the oil. The harvested canola seeds are first cleaned, heated and flaked. Heating helps to soften the seeds, making it easier to extract the oil. Flaking involves rolling the seeds to rupture their outer coating. The flaked seeds are cooked in a series of heating drums or cookers. This step helps to further break down the cell walls and makes the oil extraction process more efficient. The cooked flakes are then pressed using mechanical presses to extract most of the oil. This process is known as expeller pressing. To extract the remaining oil, the pressed seed matter is treated with a solvent. The solvent helps to dissolve the oil, which is then separated from the seed solids. The extracted oil undergoes refining to remove any impurities using methods such as natural clay filters, water, organic acids, and steam.
