Résumé
Fragrance encapsulates are widely used in consumer care applications such as fabric softeners or other liquid laundry products; they provide multiple benefits, from fragrance protection in the commercial product to a controlled release and improved sensorial experience for the consumers. Polymeric fragrance encapsulates are in the scope of the EU regulation restricting the use of intentionally added microplastic particles, and industry is actively working on innovation programs to find biodegradable alternatives. However, particular attention needs to be paid to claims that a fragrance encapsulation system is biodegradable, because biodegradation test results can vary considerably depending on how a test material is prepared, which can even lead to false-positive biodegradation test results, as shown in our study. We demonstrate the importance of the sample preparation phase of the process. We show how the biodegradation level can fluctuate from 0% to 91%, depending on how the test material is isolated from a given microcapsule slurry system, and we present a method that can be used to obtain trustworthy biodegradation results.
