gelwoRx soft capsules

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.

Solutions tailored to your needs

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. We offer tailored pharmaceutical grade gelatin, and the specialties gelwoRx Dsolve and Dhydra innovations aim to solve some of the current challenges the industry faces. ​

gelwoRx™ Dsolve and gelwoRx™ Dhydra:​ clear solutions for the production of soft capsules

Lab specialist looking into soft cap

gelwoRx™ Dsolve enhances the bioavailability of a capsule by counteracting crosslinking – a natural behavior 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. Up to 40% less crosslinking has been measured compared to the gold standard for soft capsules. Over time gelwoRx Dsolve maintains this dissolution capacity and shows no signs of stickiness. It also exhibits outstanding machinability and robustness of the capsule.​


gelwoRx™ Dhydra accelerates the production time of soft capsules, by improving gel mass stability and optimizing the drying performance.
