The Application of Sodium Carboxymethyl Cellulose in Cosmetics

In today’s cosmetics market, the transparency and safety of ingredients are increasingly valued by consumers. Sodium carboxymethyl cellulose (CMC) is one of many common ingredients in cosmetics industry. The purity of CMC used in the personal care and cosmetics industry is usually a minimum of 99.5%. We will talk about the properties of CMC and its application in cosmetics industry in the following article.


Sodium carboxymethyl cellulose is a compound derived from natural cellulose. Cellulose is the main component of plant cell walls, and carboxymethyl cellulose is formed after chemical treatment by replacing the hydroxyl (OH) part of cellulose with carboxymethyl (CH2COOH). This transformation not only makes it have better solubility and thickening property, but also gives it stability in aqueous solution.

Because of the properties of CMC, it mainly plays the role of thickener, stabilizer and emulsifier in cosmetics industry. Here are some of its main uses:

Thickener: CMC can increase the viscosity of cosmetic products, so that the products have good spread-ability and adhesion. This is especially important for products such as creams, lotions and cleansers. It can ensure an even distribution of the product on the skin.

Stabilizers: Many cosmetics contain water and oil, which are two insoluble ingredients. CMC can help stabilize these ingredients and prevent them from separating. This is especially critical for products such as lotions and creams that contain oil and water mixtures.

Emulsifier: CMC also has a certain emulsifying ability, which can help water and oil form a stable emulsion, thereby improving the texture and stability of the product.

SINOCMC can supply purified grade CMC with different viscosity. If you have are interested, please feel free to contact us.
