Enzyme containing microcapsules (EMC) with desirable controlled release properties were prepared by a spray drying technique for application in laundry detergents. Functionalised polymers were developed to prepare EMC with ionic strength triggered release properties. Ionic strength changes during the laundry process result in the efficient and controlled release of the enzyme payload.
