Abstract
The present invention relates to improved matrix or core shell enzyme capsule compositions comprising certain density modifying solids and defined core structural ingredients. Using these capsule compositions, much better active stability is obtained. In addition, higher active retention is accomplished during capsule formation. Release characteristics are not compromised. In a second embodiment of the invention, the invention relates to structured heavy duty liquid compositions comprising these capsules.
