The Microencapsulation

Textile Microencapsulation picture through an electron microscopy

The Microencapsulation, also known as microshell, is a complex technique that involves the creation of polymeric shells, whether natural or synthetic, in which particles of active ingredients and scents are stored inside and thus remain and kept protected from the environment.

Smart Essences develops the microcapsules by means of Interfacial Polymerization, in order to produce microcapsules from 2 to 8 microns, which are suitable for being anchored in porous surfaces and textiles. The microcapsule protects the active principle from the action of different physical or chemical agents that can affect it, keeping its original features and improving the durability of its effects. After applying this procedure, the ingredients are gradually released when being rubbed.

The adherence of the microcapsules is achieved by incorporating binders (acrylic resins, polyurethanes,…) acting as adhesives on the support and achieving a wear resistance commitment. Smart Essences Microencapsulation Technology offers infinite new applications that improve and innovate current materials and products providing them with new and interesting properties.

Advantages of microencapsulation

Properties Conservation

The fragrances and active ingredients directly applied are exposed to constant changes in their properties due to the action of the environment. By means of the Microencapsulation the active ingredient is protected by a microshell, which makes the active ingredient or scent remain intact until the moment of its release.

Controlled release and durability

By incorporating microcapsules we ensure the release of active substances and fragrances in a controlled manner. The release only occurs when rubbing the microcapsules, when they progressively give off the product increasing its permanence.

Resistance to washing

The anchoring of the microcapsules on textiles and other porous surfaces ensures the duration of the active ingredient and scents even when subjected to domestic or industrial washing. This resistance to washing depends on the application method of the microcapsules and the presence of binders or resins in the composition. The application method must be adapted to the use and composition of the final products according to end users’ needs.
