Rapeseed Sterol ●
TL;DR. This ingredient primarily functions as a skin-conditioning lipid and emollient, helping reinforce a smooth after-feel in creams, balms, lip products, and hair conditioners. It can also support oil-phase structure and improve cushion in richer formulas.
What does Rapeseed Sterol do in a cosmetic formula?
This ingredient primarily functions as a skin-conditioning lipid and emollient, helping reinforce a smooth after-feel in creams, balms, lip products, and hair conditioners. It can also support oil-phase structure and improve cushion in richer formulas.
Is Rapeseed Sterol clean?
This ingredient is generally well-tolerated, non-fragrant, and not a common clean-standard flashpoint. The main quality considerations are residual solvents, pesticide residues, and allergen management from its agricultural source.
Is Rapeseed Sterol sustainable?
This material is plant-derived and often recovered from edible oil refining streams, which can make good use of an existing agricultural byproduct. It is expected to be biodegradable and has a lower persistence profile than many synthetic film-forming lipids.
Is Rapeseed Sterol COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic products when sourced and processed through approved physical or green-chemistry methods. Its renewable feedstock and favorable biodegradation profile align well with Green Chemistry principles, provided extraction and purification use acceptable solvents.
How does Rapeseed Sterol work chemically?
This ingredient is a mixture of lipophilic tetracyclic plant alcohols, mainly C28 to C29 molecules with a 3-beta hydroxyl group and unsaturated side chains. It is oil-phase compatible, essentially non-ionizable across normal cosmetic pH, and benefits from antioxidant support because unsaturated components can slowly oxidize.
