Emulsioaineina

Emulsioaineina, or emulsifying agents, are substances that facilitate the formation and stabilization of emulsions, mixtures of immiscible liquids such as oil and water. They work mainly by adsorbing at the oil–water interface, reducing interfacial tension, and often forming a protective film around droplets to prevent coalescence.

Emulsioaineina can be broadly categorized as molecular emulsifiers (surfactants) and particulate emulsifiers (solid particles), with some agents providing thickening or gelation to improve stability. A common framework for molecular emulsifiers is the hydrophilic-lipophilic balance (HLB) system, which helps predict their suitability for oil-in-water versus water-in-oil emulsions. Particulate emulsions, or Pickering emulsions, rely on solid particles such as silica or food-grade minerals to stabilize droplets.

Common examples include lecithin (phospholipids from egg or soy), mono- and diglycerides, polysorbates (Tween), sorbitan esters (Span), and proteins such as casein or whey. Gum arabic and other natural gums can act as stabilizers and emulsifiers in beverages and confectionery. In cosmetics and pharmaceuticals, emulsioaineina like polysorbates and certain fatty alcohol derivatives are used to create stable emulsions for creams, lotions, and suspensions.

Regulatory status varies by country; many emulsifying agents are approved for food, cosmetic, and pharmaceutical use with specified maximum levels. They are chosen based on the desired emulsion type, texture, flavor, and stability requirements, as well as potential allergen concerns.
