Abstract

Enzymes tend to be inactivated during wash by a bleach catalyst in combination with a source of organic peroxyacids. The risk of enzyme inactivation by active bleach catalyst is reduced when the release of the enzyme into the wash solution is delayed. The enzyme stability during washing together with a bleach catalyst can be improved by applying a delayed-release coating to cores which comprise the enzyme.
