What does a carbomer do in cosmetic formulations?

A carbomer is a synthetic polymer widely used in cosmetic formulations for its ability to thicken products. When included in creams and gels, it enhances the viscosity, providing a desirable texture and consistency that improves the product's performance and user experience. This thickening property helps stabilize the product and maintain its intended formulation.

While other options may describe roles that various ingredients can play in cosmetic products, carbomers specifically excel in thickening, making them essential for creating rich, creamy textures that consumers enjoy. This is particularly beneficial in hydrating products, where a thicker consistency can feel more luxurious and provide a better application experience.
