Various encapsulation techniques are available for improving the efficiency of aroma chemicals in fragranced consumer products. Encapsulation techniques are still being optimised in terms of fragrance performance, scaling up and costs. Environmental aspects are becoming more important, putting constraints on the use of non-biodegradable fragrances, which are used in large excess and end up in the environment. Encapsulation could be the tool to make more efficient use of fragrances as slow or controlled delivery systems. Encapsulation opens the way in using biodegradable fragrances which could not be used before because of the too low chemical stability (during processing, storage or usage). A straightforward route to develop microencapsulated fragrance materials is to adapt existing methods developed for pharmacy, foods, agriculture or cosmetics. However, industrial constraints (cost in use) should be taken into account in a cost-competitive market area such as consumer products.
