Question 1

What does Brassica Campestris  Sterols ND do in a cosmetic formula?

Accepted Answer

This ingredient primarily functions as a skin-conditioning lipid, helping soften the feel of formulas and support the skin barrier. It can also add body and improve the richness of creams, balms, and anhydrous products.

Question 2

Is Brassica Campestris  Sterols ND clean?

Accepted Answer

From a clean beauty perspective, this ingredient is generally well-tolerated, low in sensitization concern, and not a common restricted-list issue. The main quality questions are supplier documentation, residual solvent control, and whether the plant source and processing route meet a brand’s standard.

Question 3

Is Brassica Campestris  Sterols ND sustainable?

Accepted Answer

This material is typically plant-derived from oilseed processing streams, which can fit well with renewable sourcing and byproduct use. It is expected to be biodegradable and has low persistence concern compared with silicone or fluorinated film-formers.

Question 4

Is Brassica Campestris  Sterols ND COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic standards when sourced from approved plant feedstock and processed with permitted extraction or refining methods. Its Green Chemistry profile is favorable because it is renewable, used at low levels, and can come from existing vegetable oil production streams.

Question 5

How does Brassica Campestris  Sterols ND work chemically?

Accepted Answer

This material is a mixture of C28 to C29 sterol alcohols with a tetracyclic lipid structure and a single polar hydroxyl group, making it oil-soluble and water-insoluble. It is commonly used at low percentages in emulsions and balms, is broadly pH-stable in finished formulas, and benefits from antioxidant support because unsaturated lipid fractions can oxidize with heat, air, and light exposure.
