Rousselot®, Darling Ingredients' health brand, and the global leader of collagen-based solutions1, today announced that the European Patent Office (EPO) has granted the company's patent application for Rousselot StabiCapsTM a gelatin excipient solution that improves soft gel formulation and stability.


Due to its natural properties, functional benefits and suitability for immediate release dosing, gelatin is the most common gel forming agent used in soft gel production2. Launched in 2018, StabiCaps features gelatins that offer superior shell stability and Active Pharmaceutical Ingredient (API) release levels, when compared to standard gelatins, according to the company. With strong shell stability and the ability to properly dissolve over time, StabiCaps minimises the risk of cross-linking reactions in soft gel production, a common challenge faced by nutraceutical and pharmaceutical manufacturers when using reactive fills.
