Gelatin has consistently proven itself as a natural, safe, and highly versatile excipient for most delivery forms in use today. As a trusted industry leader, Rousselot brings deep expertise and a proven track record to this space, having reliably supplied high-quality gelatins to the softgel and capsule segments across all global geographies for many years.

- StabiCaps™ - Getting your softgels just right - Find out more here
Because of its unique functional capabilities and excellent dissolution properties, gelatin is by far the main ingredient in soft gelatin capsules. But when working with specific fills, manufacturers may experience cross-linking issues that unfavourably affect softgel stability. StabiCaps is a range of gelatins tailored to prevent crosslinking in softgels and thus to increase their stability. It is the perfect solution for the most reactive fills.
