What is NS-300\u00ae<\/sup><\/span><\/strong><\/p>\n\n\n\n

NS-300\u00ae<\/sup> (carmellose) is a cellulose-based disintegrant with excellent wicking properties.
NS-300\u00ae<\/sup><\/span> acts as a passageway for water and has the effect of allowing water to quickly permeate the inside of the formulation.
No organic solvents are used in the manufacturing process, so there is no need to worry about residual solvents.<\/span><\/p>\n\n\n\n
