    Kollicoat® IR is one of our true multitalents for instant release

    As instant release film former, Kollicoat® IR combines exceptional coating quality with simple, robust processing. As wet binder, it combines powerful binding with no peroxides at all. And all those characteristics also make it a great pore former for sustained release formulations.

    Kollicoat® IR is a robust yet flexible polyvinyl alcohol/polyethylene glycol graft copolymer. This water-soluble film-forming agent is ideal for manufacturing instant-release coatings for solid dosage forms – and for applications such as binding, pore forming and drug layering. Kollicoat® IR’s high pigment-loading capacity makes the spraying process easier and faster. And because dispersions made using Kollicoat® IR have low viscosity despite their high solids content, coating can be significantly accelerated. The result? Highly reliable, cost-effective processes that produce first-class results every time.

    Kollicoat® IR - Powerful binder. No peroxide formation.

    Kollicoat® IR is not only a perfect solution for instant release film-coating – it can be also used for various other applications. As wet binder, it provides high binding efficiency. Due to its low viscosity values in aqueous solutions, easy processing in a vast process parameter range is assured. Furthermore, Kollicoat®IR does not contain or form any peroxides along the life time of a pharmaceutical product.

    Polyvinyl alcohol-polyethylene glycol graft copolymer for instant-release coatings and quick-dissolving formulations


    Evaluating various wet binders to gain lactose based agglomerates applicable for ODT

    The aim of this work was to investigate the performance of various wet binders onto the properties of ODTs based on agglomerates, deriving from a high shear granulation process. Furthermore, the impact of the formulation on the disintegration characteristics was investigated.


    Successful Binding of Peroxide Sensitive APIs

    In this live webinar, experts will showcase how to formulate a peroxide-sensitive drug using a binder that combines high binding strength with no peroxide formation at all.


    Challenges in Binding Peroxide-Sensitive APIs

    Excipients are crucial for effective drug formulation, and excipient manufacturers continue to make advances in technology designed to address the formulation challenges presented by new drug substances. Pharmaceutical Technology magazine talked with Dr. Bernhard Fussnegger, Global Development and Technical Marketing at BASF, about the excipient developer’s family of peroxide-free excipients that are recommended for APIs sensitive to oxidation.
