Natural antifoaming agents are substances derived from natural sources, such as plants, minerals, or animal fats, that help reduce or prevent foam formation. Unlike synthetic agents, which may have adverse environmental impacts or safety concerns, natural alternatives offer a more sustainable and eco-friendly solution. Commonly used natural antifoaming agents include vegetable oils, animal fats, natural silicates, and certain proteins.

HPMC is produced by the etherification of cellulose with propylene oxide and methyl chloride. The degree of substitution varies, leading to different molecular weights and rheological properties. On the other hand, HEC is synthesized by reacting cellulose with ethylene oxide, resulting in an ether that provides unique solubility and viscosity characteristics.
