Carbomer is a thickener that helps to control the viscosity and fluidity of cosmetics. It also helps insoluble solids disperse and suspend in liquids, preventing the separation of water and oil from the solution. They also absorb and retain water, which expands by 1000 times in water. Such ingredients are commonly used in gel formulations, where when mixed with water, they form a sticky glue. On the list of cosmetics ingredients, Carbomer is sometimes associated with numbers such as 1342,1382, 940,941 and 934P, which represent only the specific molecular weight and composition of the polymer. Carbomer is widely used in personal care products, such as hair gel, facial moisturizing cream, sunscreen, shampoo, anti-aging essence, eye cream, facial cleanser and exfoliation.
