Want to know more about CO2 Encapsulation?


CO2 encapsulation by a scCO2 spray offers a versatile method of adding functionality to your product. FeyeCon can create triggered release for moisture, Ph, microbiology, rubbing, heat, etc. We can also increase the stability and extend the shelf-life of the product by creating a shell for oxygen, UV, or moisture. This is achieved by first spraying a dispersion, emulsion or molecular solution and then removing the carrier phase for triggered release.

Our experience with CO2 encapsulation

Over the past thirty years, we have successfully used our supercritical technology to produce:

  • Encapsulated nutraceuticals for taste masking (Fe, Mg, plant extracts, etc.)
  • Humidity release coatings for fragrances for deodorants
  • Slow release for cosmetic ingredients
  • Stabilized natural pigments for lipstick and shelve life
  • Triggered release peptides in the intestines
  • Controlled release system for various enzymes in food or cosmetic
  • Increased shelve-life by a factor 10 for active pharmaceutical ingredients
  • Increased bioavailability for pharmaceuticals reducing active increasing patent life

We have basically concluded “no limitations” for functionality when using our CO2 encapsulation techniques.

The basics of CO2 encapsulation

CO2 encapsulation is the process of enveloping an active compound (solid, liquid or even gaseous) into a coating material. The active compound forms the inner core which is enclosed in a capsule material.


Coating materials can be selected based on the function of the targeted applications, such as water-free dying, from a wide range of materials (either natural or synthetic). FeyeCon can deliver different types or coated particles for triggered release: mononuclear, polynuclear or matrix-like.


CO2 provides the perfect inert medium in which sensitive actives are well-preserved during processing since the temperatures can be kept well below 50⁰C.


The CO2 encapsulation is a one-step process which can be operated either by batch or continuously. The resulting encapsulates are ready to be used without any post treatment. Our CO2 extracts function as a carrier medium (solvent) and leave no “solvent” traces behind after depressurization.


CO2 encapsulation with triggered release is a tailor-made technology which largely depends on the client. With feasibility studies, piloting and toll manufacturing, FeyeCon can support partners developing new products based on this unique and sustainable technology. In the past we have partnered with various industries and can offer qualified support and specific knowledge on scientific processes and the legality of ASME, CE, cGMP or HACCP.
