Sodium Glycolate

Excipient (pharmacologically inactive substance)

What is it?

Sodium glycolate is the sodium salt of carboxymethyl ether. Starch glycolates are from potato, rice, wheat or corn origin. Sodium glycolate is a white to off-white, tasteless, odorless, relatively free flowing powder.

Sodium glycolate is used as a pharmaceutical grade dissolution excipient for tablets and capsules. Sodium glycolate 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 effect the amount of active ingredient absorbed, thereby decreasing effectiveness. [1] [2]
