description Product Description
Span 20 is widely used as an emulsifier in the food industry, helping to blend ingredients that typically do not mix well, such as oil and water. It is also utilized in cosmetics and personal care products to stabilize formulations and improve texture. In pharmaceuticals, it aids in the creation of creams and ointments by ensuring consistent mixing of components. Additionally, Span 20 serves as a surfactant in industrial applications, facilitating processes like cleaning and degreasing. Its ability to reduce surface tension makes it valuable in various formulations requiring smooth and stable mixtures.
