METHOCEL™ A4C Premium has the same performance as METHOCEL™ A4C, except this premium product is pharmaceutical compliant.
Methocel™ A4C Premium is a water-soluble polymer that is based on high purity and non-ionic cellulose ether. It has a low viscosity range of 320 to 480 cps. Methocel is used as a thickener, binder, and film former. Further, it functions as a suspending aid, stabilizer, surfactants, lubricants, protective colloids, and emulsifiers. Methocel contributes to economic advantages since properties are simultaneously present.
