Sodium Starch Glycollate USP/BP

Sodium starch glycoate is a whitish, tasteless, odourless powder. It is the sodium salt of carboxymethyl ether. Starch glycolates are rice, potato, wheat or corn in origin. Sodium starch glycolate is used as a pharmaceutical grade dissolution excipient for tablets and capsules. It absorbs water rapidly, resulting in swelling which leads to rapid disintegration of tablets and granules. It is used as a disintegrant, a suspending agent and as a gelling agent. Without a disintegrant, tablets may not dissolve appropriately and may affect the amount of active ingredient absorbed, thereby decreasing effectiveness.
