Carbomer is widely used as a thickening, suspending, and emulsifying agent in pharmaceuticals, cosmetics, and personal care products. It helps stabilize formulations by increasing viscosity and controlling the flow of liquids. In topical gels and creams, carbomer provides a smooth texture and enhances the delivery of active ingredients. It is commonly found in acne treatments, sunscreens, lotions, and eye drops due to its ability to form clear gels and maintain product consistency. In drug delivery systems, it can control the release rate of medications and improve adhesion to skin or mucosal surfaces. Its responsiveness to pH allows it to act as a controlled-release matrix in some oral and topical formulations.
