Answered by GPT-5 mini AI
An emulsion is a mixture of two immiscible liquids (usually oil and water) in which one liquid is dispersed as small droplets throughout the other. Emulsifiers (surfactants) stabilize emulsions by reducing interfacial tension and preventing droplet coalescence.

Example product: lecithin (e.g., soy or egg lecithin), commonly used as an emulsifier in foods like mayonnaise and in cosmetics.
