Pharmaceutical-grade hydroxyethylcellulose (HEC) compliant with USP/NF, EP, and JP monographs.
Highly consistent rheology and viscosity performance across batches, ensuring robust process control in sterile manufacturing.
Excellent cold-water solubility with rapid hydration and minimal claying or fisheyes.
Non-ionic, non-toxic, and non-irritating—suitable for ophthalmic, oral, and topical dosage forms.
Stable across a broad pH range (3–11) and compatible with common preservatives, electrolytes, and active pharmaceutical ingredients (APIs).
Ophthalmic solutions and suspensions (e.g., artificial tears, anti-inflammatory eye drops).
Oral liquid formulations including syrups, suspensions, and elixirs requiring viscosity control and suspension stability.
Topical gels and creams for dermatological and transdermal delivery systems.
Controlled-release matrix tablets and mucoadhesive buccal films.
