CLP Regulation: How to classify and label microencapsulated substances
Microencapsulated substances should be considered as mixtures. This was clarified by the participants at the CARACAL meeting at the beginning of July at the request of the EU Commission. The Commission is looking for a way to classify and label formulations that contain microencapsulated substances and are released after a certain period of time.
No consensus
Nevertheless, not all representatives of the authorities agreed with this decision. While the representatives of Germany, Sweden and Austria argued for a definition as a mixture, the representatives of the Netherlands said that the capsule should be considered as a separate form, analogous to the packaging of detergents, and classification should be based solely on the contents of the capsule. The discussion was prompted by a request from the competent Austrian authority in 2022 on how formulations with microencapsulated substances should be classified.
Definition and application of microencapsulated substances
In microencapsulation, an active ingredient is embedded in a shell for reasons of solubility, reactivity or stability.
The technology is used for the following substances, among others:
- for pesticides and biocidal active substances
- for fragrances in detergents
- for flavorings in the food industry
The EU Commission is now asking for comments from those affected as to whether a "specific interpretation" is necessary in certain cases.
In this context, we would like to draw your attention to our Training Classification and labeling of substances and mixtures according to the CLP Regulation on November 5 and 6, 2024.
