What is Emulsifying Agent?
An emulsifying agent (emulsifier) is a substance that stabilises an emulsion by reducing interfacial tension between two immiscible liquids (usually oil and water). Emulsifiers have an amphiphilic structure — a hydrophilic (water-loving) head group and a hydrophobic (oil-loving) tail. They form a film at the oil-water interface, preventing droplets from coalescing. Examples include lecithin, soap, and detergents.

Food industry: lecithin in mayonnaise and chocolate; cream homogenisation; pharmaceutical emulsions and creams; cosmetics and lotions; paints and coatings; agrochemical formulations; industrial cleaning products
Generally low toxicity for food-grade emulsifiers (lecithin, mono/diglycerides). Some synthetic emulsifiers may be irritating. Consult SDS for specific compounds. Anionic and cationic surfactants at high concentrations can irritate skin and mucous membranes.
