      in foods, any of numerous chemical additives that encourage the suspension of one liquid in another, as in the mixture of oil and water in margarine, shortening, ice cream, and salad dressing. Closely related to emulsifiers are stabilizers, substances that maintain the emulsified state. The consistency of food products may also be improved by the addition of thickeners, used to add body to sauces and other liquids, and texturizers. This class of additives has a dual purpose: they make food more appetizing by improving appearance and consistency, and they augment keeping qualities (i.e., extend shelf life).

      A number of substances in this group are derived from algae, among them algin, carageenan, and agar (q.v.). Lecithins, are also used as emulsifying agents (see lecithin).

      Emulsifiers, stabilizers, and related compounds are also used in the preparation of cosmetics, lotions, and certain pharmaceuticals, where they serve much the same purpose as in foods—i.e., they prevent separation of ingredients and extend storage life.
