hydroxypropyl cellulose
polymerHydroxypropyl cellulose (HPC) is a semi-synthetic polymer derived from cellulose through hydroxypropyl ether substitution, producing a water-soluble thermoplastic with tunable properties. It is widely used in pharmaceutical formulations as a binder, thickener, and film-former in tablets and capsules, as well as in cosmetics, food additives, and coatings where its ability to form clear films and control viscosity are valued. Engineers select HPC over alternatives like PVP or PEG when they need a cellulose-based polymer with good film-forming characteristics, thermal processability, and regulatory acceptance in food and pharmaceutical 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.
