Carbomer is widely used in cosmetics and pharmaceuticals as a thickening agent, stabilizer, and emulsifier. It helps increase the viscosity of formulations, providing a smooth and creamy texture to gels, lotions, and creams. In topical drug delivery, carbomer enhances the adherence and controlled release of active ingredients. It is commonly used in acne treatments, moisturizers, and eye drops due to its biocompatibility and ability to form clear gels. Carbomer also functions as a suspending agent, keeping insoluble particles evenly dispersed in liquid formulations. Its pH-responsive gelling properties make it ideal for use in personal care products that require stability across varying conditions.
