hydroxypropyl methylcellulose
polymerHydroxypropyl methylcellulose (HPMC) is a semi-synthetic cellulose ether derived from plant cellulose through chemical modification, classified as a water-soluble polymer with tunable rheological properties. It is widely used in pharmaceuticals as a binder, thickener, and controlled-release agent in tablets and capsules, and in construction as a water-retention and workability enhancer in cement-based products; engineers select HPMC over alternatives because it offers temperature-dependent gelation, excellent film-forming ability, and compatibility with both aqueous and some organic systems, making it versatile across formulation-sensitive applications.

Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
