Product details
Toothpaste grade sodium carboxymethyl cellulose (CMC)
Sodium carboxymethyl cellulose (CMC) is made from natural cotton fibers, through etherification, purification and drying process. Sodium carboxymethyl cellulose (CMC) appears to be white powder or granules, with good water solubility, having the functions of thickening, stabilizing emulsifying and suspending in aqueous solution.
In the toothpaste industry CMC used as thickening, excipient, adhesive, moisture sustainer and fragrance keeping. When adding CMC to the toothpaste, it can make the paste stable and at the same time get the suitable consistence.
