A synthetic high-molecular weight polymer of acrylic acid. Carbomers are thickening agents that help control the viscosity and flow of cosmetic products. They also help distribute and suspend insoluble solids into liquid and prevent the oil and liquid parts of a solution from separating. They are ingredients used in a wide range of personal care products such as styling gel, facial moisturizer, sunscreen, shampoo, anti-aging treatment, eye cream, cleanser, scrubs, hand sanitizers and disinfectants. Carbomer 980 is commonly used as a thickening agent, suspension agent, viscosity enhancer, as well as a gelling agent.
