Description

Ethyl Cellulose is a water-insoluble polymer that is derived from cellulose. It is widely used in various industries such as pharmaceuticals, food additives, coatings, and cosmetics due to its excellent film-forming and binding properties. Ethyl cellulose is formed by the reaction of cellulose with ethyl chloride, which results in the replacement of hydroxyl groups in the cellulose molecule with ethyl groups.
In the cosmetics industry, Ethyl Cellulose is used as a binding agent in hairsprays, gels, and other hair styling products to improve their hold and durability.
