Two Softgel Technologies – A World of Opportunities
RAPISOL® is GELITA’s specialized softgel gelatin platform comprising two technologies for different product needs: RAPISOL® for fast fill release and RAPISOL® Chewable for pleasant, easy-to-consume chewable softgels.
Both technologies can be processed on standard softgel equipment, helping manufacturers leverage existing production capabilities while exploring new product opportunities.
Which RAPISOL® Technology Fits Your Application?
RAPISOL®
- Fast release of the fill
- Reliable rapid softgel dissolution regardless of shelf-life
- Highly relevant for applications where consumers expect quick relief: painkillers, allergy treatments, sleep aids
and more
RAPISOL® Chewable
- Desirable chew and texture
- Fast dissolving of the shell after burst
- Brilliantly clear softgels
- Easy to formulate, processable on standard softgel equipment
- Easy to consume – no water needed
Faster Fill Release for Products Where Speed Matters
When consumers choose products such as pain relief medications, allergy treatments, sleep support products, cough and cold remedies, or energy formulations, they often expect a rapid onset of action and a positive user experience.
RAPISOL® was specifically developed to meet these expectations. In comparative testing with fresh softgels, RAPISOL® enables up to three times faster fill release compared with standard gelatin softgels, creating a meaningful point of differentiation in highly competitive pharmaceutical and nutraceutical markets.
Manufactured from pharmaceutical-grade gelatin that meets pharmacopoeial standards, RAPISOL® can be processed on standard softgel equipment without requiring major production changes.
Key Benefits of RAPISOL®
Reliable Rapid Release Throughout Shelf Life
Fresh gelatin softgels generally show good dissolution characteristics. However, RAPISOL® softgels deliver significantly faster fill release than standard gelatin capsules from the outset. In simulated gastric fluid, approximately 80% of the fill is released within five minutes, supporting rapid product performance.
This performance advantage remains highly relevant over time. Stability studies have shown that standard gelatin softgels can exhibit a noticeable slowdown in fill release after accelerated storage. In contrast, RAPISOL® maintains a release profile comparable to that of freshly manufactured capsules, even after six months under accelerated storage conditions at 40°C / 75% relative humidity.
The result is a softgel technology that combines fast release, reliability, and shelf-life stability, making it particularly suitable for applications where consumers expect quick results.
Fast Release in a Chewable Format Consumers Enjoy
Consumer demand for convenient, enjoyable supplement formats continues to grow. Products that are easy to take on the go and do not require water are becoming increasingly important across global nutrition markets.
RAPISOL® Chewable extends softgel technology into a pleasant chewable format. It combines the high active-loading capacity and fill protection of traditional softgels with a consumer experience more commonly associated with gummies and other chewable formats. This creates new opportunities for manufacturers seeking innovative delivery solutions for oily and paste-like fills.
Key Benefits of RAPISOL® Chewable
Unrivalled Chew, Mouthfeel and Texture
RAPISOL® Chewable was developed to provide a soft chew, pleasant mouthfeel, and fast-dissolving shell. Compared with commercially available chewable softgel alternatives, RAPISOL® Chewable requires less bite force, making capsules easier and more comfortable to consume.
The technology is not limited to oil-based fills. Manufacturers can also formulate with paste-like fills, enabling sensory experiences that move even closer to confectionery-style formats while maintaining the advantages of softgel delivery.
Benchmark testing against two commercially available Omega-3 chewables demonstrated:
- Up to 50% lower hardness (softer chew)
- Up to 33% lower chewiness (easier to chew)
Why Choose RAPISOL®?
Whether your focus is rapid fill release or creating innovative chewable formats, RAPISOL® provides manufacturers with differentiated softgel technologies that address evolving consumer expectations while utilizing existing production infrastructure.
Combined with formulation expertise from the GELITA Pharma Institute, RAPISOL® helps bring innovative softgel concepts from idea to market with greater confidence and speed.
