ETHYLCELLULOSE.

Valuable CAS 9004-57-3 / BINDING, FILM FORMING, VISCOSITY CONTROLLING

Ethylcellulose is a plant-derived polymer primarily valued for its multifaceted role in enhancing cosmetic formulations. It functions as a robust film former and stabilizer, contributing to superior product texture and durability. This ingredient also acts as an emollient, creating a subtle, protective layer on the skin.

Science

Mechanism of Action

On the skin, Ethylcellulose precisely forms a thin, moisture-resistant film that offers a protective barrier against external aggressors while actively minimizing transepidermal water loss. Within formulations, its hydrophobic nature is crucial for stabilizing both oil-in-water and water-in-oil emulsions, ensuring ingredient integrity. It also meticulously regulates viscosity, binds various components, and facilitates the controlled, extended release of active ingredients, optimizing their dermal delivery and sustained efficacy.
