What role does a gellant serve in a cosmetic product?

The function of a gellant in a cosmetic product is primarily to give the product a gel-like consistency. Gelling agents are substances that can transform liquids into gels, which can improve the texture and feel of the product when applied to the skin. This characteristic enhances the overall user experience, making the product more appealing and easy to apply. Gellants can create a smooth and spreadable texture, which is often desired in formulations such as gels, creams, and lotions.

While some gelling agents may contribute to shelf stability or act as a mild thickener, their primary role is to create and maintain that desired gel-like consistency. The other options pertain to different roles that ingredients might play in cosmetic formulations but do not specifically apply to the function of gellants.
