  • Applications

    Lactoglobulins, beta- (beta-lactoglobulin), CAS 9045-23-2 is a major whey protein with several industrial applications: in food processing it serves as an emulsifier, foaming agent, and stabilizer in dairy, beverage, and bakery formulations, and it is commonly used as a carrier and encapsulation matrix for flavors, aromas, and other active ingredients; in cosmetics and personal care it functions as an emulsifier, thickener, and texture-enhancer in creams, lotions, and hair care products; in pharmaceutical formulations it may be used as an excipient and carrier for active ingredients, supporting stabilization and sometimes controlled release; in polymer and coating applications it can be processed into bio-based films or protein-based binders, contributing to bio-based polymers and coatings; and it may be employed as an encapsulation matrix for time-release of fragrances or actives, subject to local regulations and formulation limits.
