Abstract
The invention concerns solid granulates of a system comprising at least a hydrophobic organic active substance (for example an active detergent substance) encapsulated in solid particles of an alkali-water soluble organic polymer derived by emulsion polymerisation, said particles being dispersed in and encapsulated by a matrix in a water soluble or water dispersible dry organic compound. The invention also concerns the use of said granulates in detergent compositions, in particular for cleaning hard surfaces or for washing clothes and the detergent compositions.
