The present invention relates to aqueous capsule suspension concentrates based on polyurea shell material containing the reaction product of a NCO terminated polyester-polyol polyisocyanate prepolymer with a polyamine with less than 3 amino groups reactive towards NCO groups and an encapsulated hydrophobic core containing an ingredient, e.g. an active ingredient, in particular an agrochemical ingredient, the production thereof and the use thereof as a formulation, in particular agrochemical formulation, that provide better biodegradability.
