Camelina Sativa Seed Oil

Camelina sativa seed oil is an emollient lipid used at moderate-to-high levels in moisturizers to reduce transepidermal water loss; as a non-volatile, non-fragrant fixed oil it is generally well-tolerated and not intrinsically irritating. Clinical experience and patch-test data for similar seed oils suggest low rates of irritation, but eczema-prone patients can still react to botanical trace components or oxidation byproducts in poorly stabilized oils. Given real-world variability in refinement and stability, I rate it very gentle but not fully inert. Safety Notes: In commercial skincare it appears at very low levels (~0.1–0.5%) as a supporting emollient in complex creams/lotions where multiple plant oils are used, and commonly around 1–10% in moisturizers, facial oils-in-water emulsions, and barrier-repair products. High-strength consumer products include anhydrous facial/body oils and balms where camelina is the primary oil phase (typically 30–80%), and single-ingredient/“100% camelina seed oil” products sold OTC reach 100%. It is primarily a leave-on emollient; rinse-off cleansers usually keep it low (often ≤1–5%) due to surfactant system constraints and sensorial considerations.
