Is e1525 vegan?

E1525 is the E-number for hydroxyethyl cellulose, a modified carbohydrate polymer used primarily as a thickening agent, stabilizer, and gelling agent. It is manufactured by reacting purified cellulose, typically extracted from plant sources such as wood pulp or cotton linters, with ethylene oxide under alkaline conditions. In commercial applications, it appears in various food products to enhance viscosity and stabilize emulsions, as well as in dietary supplements, pharmaceuticals, and cosmetics.

This ingredient is vegan because its production relies entirely on plant materials and synthetic chemical processes. The starting material is plant cellulose, and the modifying agents are chemically synthesized without the use of animal products or animal-derived processing aids. Because animal inputs are absent throughout the manufacturing process, food and supplement items containing E1525 are suitable for a vegan diet.
