Sodium carboxymethyl starch (CMS-Na), also known as carboxymethyl starch, is an anionic starch ether and an electrolyte soluble in cold water. It is a type of modified starch that belongs to the ether starch category, offering water-soluble anionic polymer characteristics. CMS-Na is resistant to molding and easily soluble in water when the degree of substitution exceeds 0.2. In aqueous solution, CMS-Na demonstrates stability and excellent performance, providing functions such as bonding, thickening, water retention, emulsification, suspension, and dispersion.
High-temperature resistant starch cellulose
High-temperature resistant starch cellulose undergoes chemical modification to enhance water solubility and salt resistance. This involves increasing hydration groups in starch and simultaneously employing high temperature and solvents to physically modify the particle morphology of starch. These enhancements elevate the product's water solubility and salt resistance by introducing various modifying groups that confer resistance to high temperatures. As a result, its temperature resistance is boosted to over 130°C, with some models even usable at 150°C in the indoor evaluation system*. Furthermore, it ensures effective filtration loss reduction at low to medium temperatures, guaranteeing a broad operating temperature range.
