A foaming agent is a substance that helps create foam by trapping air in a liquid. These agents are commonly used in various industries, including food, cosmetics, and cleaning products. They work by reducing the surface tension of the liquid, allowing bubbles to form and stabilize. In the food industry, foaming agents can enhance the texture of products like whipped cream and mousses. In cleaning products, they help improve the effectiveness of detergents by creating a lather that can lift dirt and grease. Common examples of foaming agents include soap, detergents, and whipped cream stabilizers.
