Effective and reliable moisture protection for your active ingredients
Kollicoat® Protect is a combination of water-soluble Kollicoat® IR and polyvinyl alcohol. This instant release coating is highly impermeable to water – making it ideal for moisture-sensitive active ingredients and greatly increasing formulation stability. What’s more, processing is fast and straightforward: this highly flexible film former can be prepared at room temperature, and no plasticizer is required. Thanks to the polymer’s low viscosity, it is possible to create spray suspensions with a solids content of 20 percent – for exceptionally cost-efficient manufacturing processes.
|Chemical nature:||Owing to the special spray-drying process for Kollicoat® Protect, the polymers are embedded in one another to such an extent that they cannot separate. The powder has good flowability and dissolves rapidly in water.|
|Chemical name:||Polyvinyl alcohol-polyethylene glycol copolymer and polyvinyl alcohol (PVA)|
|Applications:||Together with pigments Kollicoat® Protect gives an excellent moisture protection and taste masking effect. Further to this it can be used as a peroxide-free wet granulation binder or as a pore former in sustained release coatings.|
