In many applications (textiles, pharmaceuticals, cosmetics, etc.), protection of active agents against mechanical damage or chemical, thermal and UV degradation is often needed. In addition, slow and controlled release properties of these active agents are sought for a longer lifetime and a better dosage.
Our process allows encapsulation in silica microspheres (MAT424)of different active agents for usage in textiles, cosmetics, biological or pharmaceutical industries. For example, results for the encapsulation of cosmetic oils show encapsulation rates of up to 70-90% wt. with particles sizes of 10 to 20 microns.
