Zein

What Zein is & what it does

Zein is a natural protein obtained from corn (maize), belonging to the prolamin family of plant storage proteins. In cosmetics it is used as a film former and hair- or skin-conditioning agent, able to form a thin, flexible coating that can improve product wear and feel. Because it is film-forming, it can help long-lasting formulas, including some sunscreens and color cosmetics, resist transfer and water.

What does Zein do in skincare?

Zein is a corn-derived protein used mainly as a film former and conditioning agent. It can form a thin, flexible coating that improves product wear, feel, and resistance to transfer. In long-lasting formulas, including some sunscreens and color cosmetics, this film can help the product stay put.

Is Zein natural or synthetic?

Zein is natural in origin, being a protein extracted from corn (maize). It is obtained through processing of the grain rather than built up by chemical synthesis. The finished ingredient is therefore plant-derived.

Is Zein vegan?

Zein is derived from corn and contains no animal material, so it is generally suitable for vegan formulas. The vegan status of a finished product still depends on its other ingredients and on supplier processing. Refer to the brand's labeling for a definitive claim.
