Chitosan (CMC), a versatile polymer material widely used in the cosmetics industry, has gained favor in the industry due to its unique physicochemical properties. In cosmetic formulations, CMC serves not only as a thickener, emulsifier, and stabilizer but also plays a crucial role in enhancing product texture and user experience.

Enhance Product Texture. Carboxymethyl cellulose (CMC) is a water-soluble polymer that absorbs moisture and forms a gel-like substance. In cosmetics, CMC is commonly used as a thickener to increase the product's viscosity, thereby enhancing its texture and user experience. For instance, in skincare products like face creams and lotions, the addition of CMC makes the products easier to apply and helps form a protective layer that prevents moisture loss and keeps the skin hydrated. Additionally, the thickening effect of CMC can improve product stability and storage life, reducing the likelihood of separation and spoilage.

Achieving oil-water uniformity. Cosmetics typically contain both water and oil components. To achieve oil-water uniformity, emulsifiers are added. Carboxymethyl cellulose (CMC), a surfactant, reduces the surface tension between oil and water, allowing for a more uniform mixture. During the emulsification process in cosmetics, CMC effectively encapsulates oil droplets, preventing them from clustering or settling, thus enhancing product quality and effectiveness. Additionally, CMC's emulsifying properties help the active ingredients in cosmetics penetrate the skin more effectively, enhancing their performance.

Maintaining Product Stability Various components in cosmetics can react with or separate from each other, altering the product's properties and effects. Carboxymethyl cellulose (CMC) acts as a stabilizer, helping to maintain the stability of the product, thereby ensuring long-term quality and performance. In cosmetics, CMC's stabilizing role is primarily reflected in two aspects: first, preventing stratification and sedimentation, maintaining the product's uniformity; second, inhibiting the growth and reproduction of microorganisms, thus extending the product's shelf life.

improving the extensibility and adhesion of cosmetics. In addition to the aforementioned functions, carboxymethyl cellulose (CMC) can enhance the extensibility and adhesion of cosmetics. In makeup products, CMC improves the product's uniformity and adhesion, making the makeup more lasting. Moreover, CMC's moisturizing properties make the makeup look more natural and less likely to smudge. In hair care products, CMC enhances the product's adhesion, making the hair smoother and easier to comb.
