What is the function of surfactants in cosmetic products?

Create fragrance
Reduce surface tension and increase spreadability
Thicken creams
Preserve formulas

The correct answer is: Reduce surface tension and increase spreadability

Surfactants play a crucial role in cosmetic products primarily by reducing surface tension, which allows for improved spreadability and better wetting of surfaces. This characteristic enables surfactants to facilitate the mixing of water with oil-based ingredients, creating a smoother application and enhancing the overall texture of the product. By reducing the surface tension, they help disperse other ingredients more effectively, ensuring a more uniform product performance. Surfactants also contribute to the cleansing action in formulations, allowing dirt and oil to be lifted away from the skin or hair, which is essential in many cosmetic applications. Therefore, their ability to lower surface tension not only improves the usability of the product but also enhances its effectiveness.
