Question 1

What does BRASSICA CAMPESTRIS SEED OIL / RAPESEED SEED OIL do in a cosmetic formula?

Accepted Answer

This ingredient is primarily an emollient and skin-conditioning lipid, used to soften skin, reduce moisture loss, and improve slip in creams, balms, oils, and hair products. It can also act as a carrier for oil-soluble actives and pigments.

Question 2

Is BRASSICA CAMPESTRIS SEED OIL / RAPESEED SEED OIL clean?

Accepted Answer

From a clean beauty perspective, this ingredient is generally well-tolerated and low-friction on restricted lists. Refined grades have very low protein residue, while unrefined grades may carry more natural odor, color, and oxidation variability.

Question 3

Is BRASSICA CAMPESTRIS SEED OIL / RAPESEED SEED OIL sustainable?

Accepted Answer

This material is plant-derived, renewable, and readily biodegradable. Its sustainability profile depends on farming practices, land use, pesticide inputs, and traceable sourcing rather than inherent persistence in the environment.

Question 4

Is BRASSICA CAMPESTRIS SEED OIL / RAPESEED SEED OIL COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards when the sourcing and processing methods meet the standard’s requirements. It aligns well with Green Chemistry principles because it is renewable, biodegradable, and typically produced through relatively simple extraction and refining steps.

Question 5

How does BRASSICA CAMPESTRIS SEED OIL / RAPESEED SEED OIL work chemically?

Accepted Answer

The molecule profile is mainly triglycerides rich in oleic, linoleic, and alpha-linolenic fatty acids, giving it a fluid feel and moderate oxidative sensitivity. It is commonly used from low single-digit levels up to much higher levels in anhydrous products, and formulas often pair it with antioxidants such as tocopherol to support rancidity control.
