Lecithin powder is a versatile substance commonly used in the USA across food, pharmaceutical, and cosmetic industries. Derived from sources like soybeans, sunflower seeds, or eggs, it functions primarily as an emulsifier, helping blend ingredients that typically separate, such as oil and water. In food processing, lecithin powder improves texture, shelf life, and moisture retention. It is also utilized in dietary supplements for its phospholipid content. In pharmaceuticals and skincare, it aids in stabilizing formulas and enhancing absorption. Its powdered form allows for easy handling and precise dosing, making it a practical choice in both commercial and industrial applications.
