sodium hexametaphosphate is an inorganic substance with the molecular formula (NaPO3)6, a white powder crystal or a colorless transparent glass flake or block solid. Soluble in water, insoluble in organic solvents.

Sodium carboxymethyl cellulose (CMC-Na) is an organic compound with the chemical formula [C6H7O2(OH)2OCH2COONA]n, a carboxymethylated cellulose derivative and the main ionic cellulose rubber.

The molecular formula of potassium sorbate is C6H7O2K, white to light yellow scaly crystals, crystal particles or crystal powder, odorless or slightly odorless, easily absorb moisture, oxidize and decompose, and discolour when exposed to air for extended periods of time.

Sodium carboxymethyl cellulose is usually an anionic polymer compound obtained by reacting natural cellulose with caustic alkali and monochloroacetic acid, with a molecular weight ranging from several thousand to one million. CMC-Na is white fibrous or granular powder, odorless, tasteless, hygroscopic, easy to disperse in water to form a transparent colloidal solution.
