gelwoRx™: functional bio-compatibility

Gelatin is a consumable form of collagen, which is the body’s own primary protein in connective tissue, skin, and bones. Gelatin is among the most widely used ingredients in pharmaceutical and medical applications, and with good reason: gelatin is almost universally tolerated, it displays very useful elasticity and clarity features, it melts at body temperature, and it is thermoreversible.

All of PB Leiner's pharmaceutical gelatin solutions find their place in the gelwoRx product family. Our gelatin makes for a wide range of applications, from capsules, and tablets to wound care. Above all, our intention is to offer functional solutions. With our tailored pharmaceutical grade gelatin, we aim to solve the current challenges the industry faces.

gelwoRx™ Dsolve: advanced solutions for reduced crosslinking and fast dissolution

The gelwoRx™ Dsolve product range has been specially designed to provide advanced solutions for reduced crosslinking and fast dissolution of soft caps.

Crosslinking is a natural phenomenon in gelatin by which gelatin molecules link together and dissolve more slowly due to circumstances such as humidity or storage temperature, or the chemical properties of a capsule’s filling.


Dsolve significantly reduces the soft caps’ crosslinking behavior and boasts superior dissolution performance compared to the gold standard in soft caps gelatin. Moreover, it guarantees a rapid filling release and improved stability and increased shelf life of the final dosage formulations.
