Sodium carboxymethyl cellulose (CMC), a water‑soluble cellulose‑derived polymer, is widely used in the cosmetics and personal care industry as a multifunctional additive. It primarily acts as a thickener, stabilizer, emulsifier, suspending agent, and film‑former, enhancing product texture, stability, and sensory experience. In skincare products like creams, lotions, and serums, CMC stabilizes oil‑water emulsions, prevents phase separation, improves spreadability, and forms a protective film on the skin to boost moisture retention. In hair care items such as shampoos and conditioners, it adjusts viscosity, suspends active ingredients evenly, and enhances foam quality. For cleansers and body washes, CMC improves lather stability and skin‑friendly texture. In makeup products like foundations and eyeshadows, it functions as a binder and film‑former to ensure uniform color dispersion and long‑lasting wear. Additionally, CMC is used in oral care products like toothpaste to control consistency and adhesion, and in sheet masks and hydrogel patches to facilitate ingredient delivery and skin adherence. Its biocompatibility, non‑irritating nature, and versatility make it a foundational ingredient across diverse cosmetic formulations.
