Zein ●
TL;DR. This ingredient is primarily a plant-protein film-former used to create a flexible, water-resistant layer on skin, hair, or nails. It can also support conditioning, adhesion, and gloss in styling, makeup, and coating systems.
What does Zein do in a cosmetic formula?
This ingredient is primarily a plant-protein film-former used to create a flexible, water-resistant layer on skin, hair, or nails. It can also support conditioning, adhesion, and gloss in styling, makeup, and coating systems.
Is Zein clean?
From a clean-beauty perspective, it is generally well-tolerated and has little restricted-list friction. Because it is protein-based, formulas should still consider trace protein sensitivity and source transparency.
Is Zein sustainable?
This material is commonly sourced from a renewable cereal-crop stream, often as a byproduct of starch or sweetener production. It is biodegradable, with the main sustainability variables coming from crop inputs, solvent use in extraction, and whether processing solvents are recovered.
Is Zein COSMOS-approved?
It is generally compatible with COSMOS-natural and can fit COSMOS-organic formulas when the agricultural source and processing route meet the standard. Its Green Chemistry profile is strong when made from renewable feedstock with recovered ethanol or other lower-concern processing solvents.
How does Zein work chemically?
This compound is a hydrophobic prolamin-type protein rich in nonpolar amino acids, which explains its film-forming behavior and limited water solubility. It is typically handled in aqueous alcohol or pH-adjusted systems, can precipitate when diluted with water, and is often used at low single-digit percentages depending on the film strength needed.
