1. The definition and common functions of sodium carboxymethyl cellulose
Sodium carboxymethylcellulose is a natural polysaccharide substance made from chemically modified cellulose. In cosmetics, sodium carboxymethyl cellulose is often used as an emulsifier, thickener and thickening agent, which can provide good texture and consistency for cosmetics and improve solubility and moisturizing properties.
2. Function and application of carboxymethyl cellulose sodium
①Increase the consistency of cosmetics
Sodium carboxymethyl cellulose can combine with water molecules to form a gel structure, which can effectively increase the viscosity and concentration of cosmetics and make liquid cosmetics denser. In cosmetics such as lotions, moisturizers, and essences, the thickening effect of sodium carboxymethyl cellulose can make the cosmetics easier to apply and stay on the skin surface.
Sodium carboxymethyl cellulose has a good moisturizing effect because its molecular structure contains abundant hydroxyl (OH) groups, which can adsorb and lock water molecules to form a moisture-locking protective film to effectively moisturize the skin. Therefore, sodium carboxymethyl cellulose is often used in moisturizing cosmetics such as moisturizers and hand creams.
③Increase the solubility of cosmetics
Sodium carboxymethylcellulose can also increase the solubility of cosmetics, making them easier to mix evenly. In some specific cosmetics, sodium carboxymethylcellulose can ensure that the cosmetics can evenly adhere to the skin by increasing the solubility and viscosity of the cosmetics, thereby achieving the best cosmetic effect.
To sum up, sodium carboxymethyl cellulose is a commonly used cosmetic ingredient, its main function is to increase the consistency, moisturizing and solubility of cosmetics. Sodium carboxymethyl cellulose has a wide range of applications and is commonly used in cosmetics such as lotions, moisturizers, and essences. At the same time, it is worth noting that in order to ensure the effectiveness and safety of use, the dosage of sodium carboxymethyl cellulose in cosmetics needs to be prepared in accordance with the proportions in the ingredient list.
