L-HPC

Low-substituted HydroxyPropylCellulose Binder and disintegrant

Low-substituted HydroxyPropylCellulose (L-HPC) is insoluble in water. The excipient absorbs water while increasing in volume. This increased volume provides a rapid tablet disintegration.

The L-HPC and NBD range from SHIN ETSU is compliant with Eur.Ph, JP and USP.

Binder and Disintegrant

As cellulose derivative, the L-HPC products have the desired properties for applications that help in the tablet manufacturing process.

Good compressibility
Binding property, even in low doses
Compatible with many active ingredients due to its non-ionic nature
Rapid disintegration
(Anti-capping)

Product range

The grades in the L-HPC range are differentiated according to their substitution percentages, particle size and particle appearance.

9 grades are currently marketed.

Grade	Mean particle size (µm)	Hydroxypropoxy (%)	Applications
LH-11	50	11	anti-capping
LH-21	45	11	direct compression, wet granulation
LH-22	45	8	direct compression, wet granulation
LH-31	20	11	wet granulation, pellet extrusion, layering
LH-32	20	8	wet granulation, pellet extrusion, layering
LH-B1	50	11	direct compression, fluidized bed granulation
NBD - 020	45	14	wet granulation
NBD - 021	45	11	direct compression, wet granulation
NBD - 022	45	8	direct compression, ODTs

These grades have differing particle sizes and substitutions which leads to different application properties.

L-HPC grades are primarily recommended for wet granulation. NBD grades are recommended for direct compression.

LH-21 and NBD-021 are the standard products.

The products in the L-HPC range are manufactured in accordance with the Good Manufacturing Practices applicable to excipients.

All the regulatory and quality documents required for registration are available on request.
