TL;DR. This ingredient is a solid structuring agent and film-forming aid that adds hardness, gloss, and water resistance to sticks, balms, mascaras, and color cosmetics.
What does Carnauba Cera do in a cosmetic formula?
This ingredient is a solid structuring agent and film-forming aid that adds hardness, gloss, and water resistance to sticks, balms, mascaras, and color cosmetics.
Is Carnauba Cera clean?
It is generally well-tolerated, with low sensitization concern and little clean-standard friction. Watchouts are mainly residual processing aids and quality sourcing rather than the molecule itself.
Is Carnauba Cera sustainable?
This material is plant-derived from harvested Brazilian palm leaves, so supply-chain quality depends on leaf-harvest practices, traceability, and worker protections. It is biodegradable as a natural ester-rich solid, though slower than simple water-soluble ingredients.
Is Carnauba Cera COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed according to the standard. It aligns well with Green Chemistry through renewable feedstock and simple physical refining, with the main limitation being land-use and social due diligence in the supply chain.
How does Carnauba Cera work chemically?
The molecule family is mostly long-chain aliphatic esters, fatty alcohols, fatty acids, and hydrocarbons, which explains its high hardness and high melting range around 80 to 86 °C. It is typically used at low single-digit levels for texture or higher levels in anhydrous sticks, and it is stable across normal cosmetic pH because it is used in the oil phase rather than the water phase.
