Can camelina oil be dangerous?
Thecamelina oil is characterised by its fluidity, lightness and non-comedogenic properties, making it suitable for all skin types for topical application. It carries no major risk in its use, as demonstrated by the FDA (Food and Drug Administration) report on camelina oil. Furthermore, it is not contraindicated in pregnant or breastfeeding women, nor in children or babies.
A concern could arise from its oxidation state. Indeed, camelina oil is concentrated in omega-3 (27.9%). However, their chemical structure, rich in double bonds and their numerous bis-allylic hydrogens, make them susceptible to oxidative degradation, which is characterised by the production of free radicals.
The nutritional and organoleptic properties of the oil will then be degraded, despite the presence of vitamin E and other antioxidants. Oxidised camelina oil (rancid) becomes comedogenic, its application on the skin will then promote the appearance of comedones, among other things. It thickens, changes colour and a characteristic odour appears.
When consumed orally, the context changes. Camelina oil is rich in omega-3 fatty acids. However, due to the ability of these compounds to prevent the formation of blood clots, taking camelina oil as a dietary supplement could interact with certain medications, such as blood thinners, and cause side effects, such as nausea, vomiting and diarrhoea.
It is crucial to consult a doctor before taking this supplement to avoid any risk.
What are the usage precautions for camelina oil?
It is important to use the camelina oil correctly in order to fully benefit from its properties. You must ensure that the oil is of good quality, and does not exhibit characteristics that might suggest the occurrence of oxidative degradation.
To do this, one must check its smell, texture, and the absence of any colour change (the "usual" colour of camelina oil being golden yellow). Before using it, it is recommended to perform a skin test in the crook of the elbow, on the inner side of the wrist or behind the ear for example, to observe any potential skin reactions.
In order to maintain the quality of camelina oil, it is important to seal the bottle tightly to prevent the presence of oxygen. Then, store it in a cool place, away from direct sunlight for proper and risk-free preservation. After opening the bottle, this oil can be kept six to eight months in the refrigerator.
Do not hesitate to consult your doctor if you have any questions or doubts.
