In skin care products, CMC (Carboxymethyl Cellulose) is a widely used ingredient. It is a water-soluble polymer derived from natural cellulose and is widely used in various skin care products due to its versatility and good skin compatibility.
1. Thickener and stabilizer
One of the main roles of CMC in skin care products is as a thickener and stabilizer. The texture and viscosity of skin care products are crucial to the consumer’s experience. CMC increases the viscosity of the product, making the skin care products more ductile and smooth on the skin. At the same time, it can also stabilize multiphase systems such as emulsions or gels to prevent stratification, agglomeration or precipitation, thereby ensuring the uniformity and stability of the product. Especially in emulsions, creams and gels, CMC can give the product a moderate consistency, making it smoother when applied and bringing a better user experience.
2. Moisturizer
CMC has good water retention. It can form a breathable film on the skin surface, lock in moisture on the skin surface, reduce moisture evaporation, and thus exert a moisturizing effect. This property makes it a common ingredient in moisturizing skin care products. Especially in dry environments, CMC can help maintain the skin’s moisture balance, prevent skin dryness and dehydration, and thus improve the skin’s texture and softness.
3. Stabilize the emulsified system
In skin care products containing a water-oil mixture, emulsification is a key process. CMC can help stabilize the emulsified system and prevent the separation of the water phase and the oil phase. By using it in conjunction with other emulsifiers, CMC can form a stable emulsion, making the product smoother and easier to absorb during use.
4. Improve skin feel
CMC can also improve the skin feel of the product in skin care products. Due to its natural polymer structure, the film formed by CMC on the skin can make the skin feel smooth and soft without feeling greasy or sticky. This makes it used in many refreshing skin care products and sensitive skin care products.
5. As a suspending agent
In some skin care products containing insoluble particles or active ingredients, CMC can be used as a suspending agent to evenly distribute these particles or ingredients in the product to prevent them from settling to the bottom. This application is very important in some facial cleansers, scrubs and skin care products containing granular substances.
6. Mild and low irritation
CMC is a mild and low irritation ingredient that is suitable for all skin types, even sensitive skin and baby skin care products. This makes it a preferred ingredient in many sensitive skin care products. Due to its natural origin and good biocompatibility, CMC does not cause skin allergies or discomfort after use.
7. Ingredient carrier
CMC can also be used as a carrier for other active ingredients. By combining with active ingredients, CMC can help these ingredients distribute more evenly on the skin, while also enhancing their stability and efficacy release. For example, in whitening or anti-aging products, CMC can help active ingredients penetrate the skin better and improve the efficacy of the product.
8. Provide a comfortable application experience
CMC can give skin care products a smooth and soft touch, improving the comfort of consumers when using the product. It can enhance the ductility of the product, making it easier for skin care products to be evenly distributed on the skin and avoiding pulling the skin.
9. Improve the shelf life of products
As a stabilizer and thickener, CMC can also extend the shelf life of skin care products. It helps products maintain their original texture and efficacy during storage by preventing problems such as stratification and precipitation.
CMC plays multiple roles in skin care products. It not only improves the physical properties and usage experience of the product, but also has good biocompatibility and low irritation, and is suitable for various types of skin care products. For this reason, CMC has become an indispensable ingredient in many skin care formulas.
