Brassica Napus Seed Oil

Brassica Napus Seed Oil is a non-fragrant oil from the same plant that gives us canola oil. It is an emollient that helps slow water loss in skin.

Cosmetic-grade rapeseed oil is mostly oleic acid (~60%), with some palmitic, stearic, and linoleic acid.

Linoleic acid is an essential fatty acid that supports the skin barrier and cells while oleic acid helps soften the skin.

Other parts of this oil include tocopherols, phytosterols, carotenoids, and ferulic acid, giving it antioxidant properties.

Overall, this is a well-regarded cosmetic ingredient and allergic reactions to it are rare (most protein allergens are removed in the refining process). It's still worth patch testing as the source of this ingredient vary by brand.

Because this ingredient is rich in oleic acid, it may not be fungal acne safe.
