What is the function of a carbomer?

A carbomer primarily functions as a thickening agent and is often used in cosmetic and pharmaceutical formulations to stabilize emulsions or suspensions. These synthetic polymers can increase the viscosity of a product, which is crucial in creating the desired texture and consistency, enabling products such as lotions, creams, and gels to maintain their structure and form during use. By helping to thicken formulations, carbomers enhance the overall user experience, ensuring that the product spreads evenly and smoothly upon application, which is significant in aesthetic treatments.

In addition to their thickening capabilities, carbomers also contribute to the formulation's emulsification process, allowing oil and water-soluble ingredients to mix more effectively. Their role as emulsifiers complements their thickening properties, showcasing their versatility in product formulation.
