MICROCAPPSULE DIRECTED TO BIOFILM, METHOD OF SUPPLYING A NON-VOLATILE FUNCTIONAL MATERIAL TO A BIOFILM AND USE OF NON-IONIC POLYSACARIDE POLYMER

摘要

a microcapsule directed to the biofilm, suitable for depositing on a biofilm from an aqueous dispersion, comprising a solid microparticle with an average diameter of 1 to 100 microns, the microparticle carrying a non-volatile functional material to be supplied to the biofilm after the microparticle has been deposited on the biofilm, characterized by the microparticle having attached to its external surface of 0.5 to 5% by weight, based on the weight of the microparticle, of non-ionic polysaccharide polymer.
