Definition of complex coacervation: This involves creating a complex of gelatin and carboxymethylcellulose by playing on the opposite electric charge of the two natural polymers.
Gelatin-based microcapsules, transparent and flexible, adjustable in diameter from 1 μ to 2 mm, presentation in slurry or powder This technology allows the manufacture of sealed microcapsules or controlled release whose release rate can be adjusted according to applications.
This type of microcapsules is also sold in a food version.
We have succeeded in developing microcapsules obtained by complex coacervation containing 35% of active ingredient for use in chemical carbonless, which could be deposited directly on the paper machine.
These microcapsules were sold at the time around the world, sometimes by complete tanker trucks.
