MICROENCAPSULATION|What is Encapsulation

In the microencapsulation process, the tiniest droplets of oil or solid particles are uniformly encased in a polymeric material. The contents of the capsule are usually released again in a targeted manner by mechanically destroying the capsule wall. Active substances are protected by the tight capsule shell. The stability of the encapsulated ingredients is improved and the product performance can be enhanced through a controlled release of the core material.

APPLICATION OF MICROENCAPSULATION

Microencapsulation is a versatile technology. It offers solutions for numerous innovations - from the paper industry to home care products, microencapsulation increases the functionality of a wide variety of active substances. Encapsulated active ingredients can be used more economically and improve the sustainability and environmental compatibility of many products. You can find areas of application for these functional products in the following application examples.

MICROENCAPSULATION TECHNOLOGY

Microencapsulation is a generic term for various processes to enclose substances in the micrometer range with a shell. The aim is often to protect active ingredients and release them in a targeted manner at a specific point in time during use.

The chemically and mechanically stable capsules are based on amino resins, for example. In addition to the high density of the capsule shell, the wall is very resistant to reactive chemicals. The core liquid can be released again in a targeted manner through pressure and shearing. However, microcapsules can also be made from biopolymers, which ensure biodegradability after use.PRODUCT DEVELOPMENT

For the development of a suitable microcapsule, the first step is the exact description of the applications and the resulting requirements for the capsule properties. The release, the size of the capsule and the specific properties of the core material are just a few parameters that influence the formulation and process development.
