Abstract: A capsule having an encapsulated material and a capsule wall encapsulating the encapsulated material. The capsule wall includes a N-acetylglucosamine/glucosamine copolymer or a derivative of such a copolymer, wherein the N-acetylglucosamine/glucosamine copolymer or a derivative of such a copolymer is derived from a raw material which has a non-animal origin. The capsules have significant compression resistance while minimizing the amount of polymer incorporated into the capsule wall and are advantageously stable in a range of products including when associated with commercially available protease containing, biological liquid laundry products.
