Immediate Release
Hypromellose – HPMC – An array of low viscosity grades ideal for use in side vented auto coaters and fluid bed applications.
PolyVinylAlcohol
A selection of premixed formulations containing polymer and plasticizers, and developed with solids content up to 25% for ready to mix and coat. Colors can also be added and formulated to customer's specifications. All colors are FD&C approved.
Functional Coatings
Hypromellose Phthalate – HPMC-P – An enteric polymer with a pH release point, best applied via an organic solvent system.
HPMCAS – pH dependent release for true enteric action with 3(L, M, H) PH points. Can be applied aqueously or with organic solvents. AquaSolve™ from Ashland.
Sodium Alginate – a pH dependent delayed release aqueous coating system that is fully GRAS for nutraceutical and dietary supplement applications. Colors can be added and all are FD&C approved.
Polymethacrylates – These polymers can be used for both enteric and pH dependent sustained-release applications. Type A, Type B, and Type C have 5.5 pH release points. Grades are available for aqueous suspension and organic solvent applications.
Carboxymethyl ethyl cellulose - CMEC™ – Enteric & controlled-release base polymer with pH sensitivity. Low pH gives slow release and high pH gives faster release. - From Freund
ZEIN – A water soluble protein from non-GMO corn. Availlable in powder for organic solvent coating or in liquid concentrate for aqueous application. Kosher, Halal, and Gluten free for nutraceutical SR applications
Flow Zein™ from Flo
Coating Premix – A choice of formulations containing enteric polymer and plasticizers, available with HPMC-P; Types A,B, and C polymethacrylates are also available for ease of operation. Colors can also be added and formulated to customer's requirements. All colors are FD&C approved.
