Selected Brochures

ARBOCEL, powdered cellulose, is a plant-based functional filler. Powdered cellulose is chemically inert and is, thus, not metabolised by the human body. Because it is not digested, it has no functional caloric value. It is commonly used by formulators as an alternative to lactose when designing medicine for lactose-intolerant patients. ARBOCEL’s binding properties and natural fiber structure lead to stable tablets with low friability.

The health science industry faces a wide variety of challenges including increased pressure to reduce costs, accelerate time to market and improve product performance.These challenges drive health science companies to find new solutions for improving time and cost efficiency in oral dosage form development and production. Formulation scientists developing direct compression formulations generally require several conventional excipients - often at high levels - to obtain good material flow, compaction, blending properties, content uniformity, carrying capacity, stability, lubricity and disintegration. Finding the proper excipient combinations and concentrations to achieve adequate solid dosage formulas is a time consuming, and often expensive, process that varies with API characteristics. PROSOLV EASYtab SP was developed to provide an innovative solution to meet these challenges.

PROSILY ODT G2 is a high functionality excipient for orally disintegrating tablet formulation, development, and manufacture. It provides the functional performance needed for today’s orally disintegrating tablet formulation challenges and offers a creamy, smooth, cool mouthfeel.

PRUV, Sodium Stearyl Fumarate, is a tablet lubricant specifically designed for formulations in which other lubricants lead to formulation and/or manufacturing challenges. As opposed to magnesium stearate, it offers advantages including: high degree of API compatibility, robustness to over-lubrication, no adverse effect on bioavailability, and improved appearance of effervescent solutions.

VIVAPUR MCG is a free flowing powder consisting of microcrystalline cellulose (MCC) and sodium carboxymethyl cellulose (Na-CMC). It can be used as a suspending agent, emulsifier, opacifier,and thickener for oral suspensions, veterinary drenches, sprays, reconstitutable powders, creams, gels and lotions.
