What is E.C.G-505\u00ae<\/sup><\/span><\/strong><\/p>\n\n\n\n

E.C.G-505\u00ae<\/sup><\/span> (Carmellose Calcium) is a chemically modified cellulosic disintegrant containing a Ca chelate structure that confers water insolubility and hydration capacity.
It rapidly absorbs the water required for swelling, resulting in a good short disintegration time.
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
