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 to the skin. 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 acts as a controlled-release agent in oral and transdermal formulations. Its mucoadhesive properties also make it useful in nasal sprays and vaginal gels, where prolonged contact with mucosal surfaces is desired.
