Hydrogenated Rapeseed Oil

Hydrogenated rapeseed oil is derived from rapeseed, a widely cultivated crop. The oil undergoes hydrogenation—a chemical process that adds hydrogen atoms to stabilise the oil, making it more solid at room temperature and extending its shelf life. This processed form is used in skincare primarily as an emollient and conditioning agent.In formulations, it works to soften the skin surface and reduce water loss, making it a gentle occlusive suitable for various product types including creams, balms and body care.

Hydrogenated rapeseed oil functions as an occlusive emollient. It sits on the skin surface and penetrates slightly into the outer layers, creating a semi-permeable barrier that traps moisture and prevents evaporation. This reduces dryness and helps the skin maintain its natural hydration levels.Because it is derived from plant material and then stabilised through hydrogenation, it tends to be well-tolerated and less likely to cause irritation compared to some synthetic alternatives.

Hydrogenated rapeseed oil is typically incorporated into finished products rather than used as a standalone treatment. Use products containing this ingredient as directed—usually daily for moisturisers or creams. If combining with other actives, apply it in your routine after water-based treatments and before occlusive products, as it can form a light barrier.

Hydrogenated rapeseed oil is generally well-tolerated and recognised as safe in cosmetics. Those with sensitivity to plant-derived oils should patch test first. Historically, there has been anecdotal concern linking rapeseed oils to fungal acne, though evidence is inconclusive.
