Introduction

Isopto Plain also known as hydroxypropyl methylcellulose (HPMC) is a polysaccharide often used as an aqueous dispersion of methylcellulose polymers. It is a semi-synthetic, non-ionic cellulose ether used as an excipient or pharmaceutical base in pharmaceuticals, foods, cosmetics, and industrial products. Isopto Plain is white to cream colored, odorless, and tasteless powder that is highly viscous, soluble in water, and forms stable gel.

Uses

Isopto Plain is used in the production of emulsions, tablets and capsules and other pharmaceutical forms due to its superior qualities such as water solubility, ease in dispersing, good resistance to salting out effects, and low irritation to the gastro-intestinal tract.
