Full Description

Hydroxypropyl methylcellulose (HPMC, hypromellose; CAS 9004-65-3) is a nonionic cellulose ether. It is used as a thickener, film former, binder, emulsifier, water-retention aid, and protective colloid in construction products such as tile mortars and plasters, as well as coatings, adhesives, and personal-care and food formulations.

Frequently Asked Questions

Is hydroxypropyl methylcellulose natural or synthetic?

HPMC (hypromellose, CAS 9004-65-3) is a modified natural polymer: it is made from cellulose, a natural polysaccharide, that has been chemically etherified with methyl and hydroxypropyl groups. The result is a nonionic cellulose ether.

What is hydroxypropyl methylcellulose used for?

HPMC is used as a water-retention and workability aid in tile mortars, plasters, and other construction products, as a thickener and film former in coatings and adhesives, and as a thickener, emulsifier, and suspending agent in personal-care and food formulations.

What is another name for hydroxypropyl methylcellulose?

HPMC is also called hypromellose and carries CAS 9004-65-3. It is a nonionic cellulose ether and classifies under HS 3912.39 (cellulose ethers, other).

What viscosity grades of HPMC are available?

HPMC is supplied in a range of viscosity grades and methyl/hydroxypropyl substitution levels selected by application, from construction grades to coating and personal-care grades. Confirm the target viscosity and specification against the Certificate of Analysis when ordering.

How is hydroxypropyl methylcellulose supplied in bulk?
