Rousselot® StabiCaps™

The proven solution for more stable soft gels

Because of its unique functional capabilities and excellent dissolution properties, gelatin is the main ingredient in soft gelatin capsules. However, producing soft gels can be sometimes challenging. Especially when working with specific fills, manufacturers may experience cross-linking issues that unfavorably affect the soft gel stability.

With StabiCaps, such stability issues can be overcome. 

STABICAPS™ offers unique benefits

StabiCaps is a range of gelatins specificallly tailored to prevent crosslinking in soft gels and thus to increase their stability.  It is the perfect solution for the most reactive fills, offering:

  • Reduced maturation time and faster drying time, improving production efficiency
  • Perfect protection of active ingredients
  • Optimal behavior in the presence of cross-linkers
  • Optimal shell stability and shelf-life
  • Optimal dissolution and API release

StabiCaps clearly outperforms gelatins presented as having reduced cross-linking ability."

StabiCaps is the result of Rousselot in-depth expertise in soft gel gelatin

To fully understand how and why cross-linking occurs, Rousselot has conducted extensive research, and identified the different parameters impacting the tendency of gelatin to cross-link. These parameters are linked to the storage conditions, the API or nutraceutical fillings containing aldehydes or antioxidants (polyphenols) as well as complex fillings with multivitamins, multi-minerals, metallic ions, or combinations of these…

To predict the behavior of gelatin in the presence of cross-linkers, Rousselot has also developed a specific testing protocol.

At Rousselot, we can provide you with the support you need to succeed.
