Abstract

Microcapsules for delivery of a liquid onto a surface such as a hard surface or a textile, such as mattress ticking, are disclosed. The microcapsules have a shell with an outer face and an inner face, the inner face encapsulating the liquid, and the liquid contains a microorganism such as a beneficial microorganism in a dormant state. The outer face of the microcapsules may comprise reactive functional groups whereby the outer face is chemically bondable, for instance covalently bondable to said surface.The microcapsules provide a beneficial microflora on said surface by rupture of the capsules deposited onto said surface to release the microorganism onto said surface. This may reduce or obviate the need for chemical antimicrobial agents to clean said surface. For surfaces which are fabrics or textiles, rupture and release may occur during use of the fabric or textile.
