A particulate carrier material is impregnated with a biocidal formulation and serves as a vehicle for introduction of the biocide into a liquid-based media, such as a surface coating or surface cleaning compositions, in order to allow controlled release of the biocide to combat bacterial, fungal, algal or like growth for an extend period of time.

Particulate carrier for biocide formulations

A granular composition, especially for incorporation in washing powder formulations, comprises at least 40% by weight of an amorphous silica and typically at least 30% by weight of a functional ingredient such as a perfume, the amorphous silica having a surface area of at least 550 m /g, a pore volume from about 1.0 to about 2.5 ml/g and a particle size of no more than 50 microns, the granules of said composition having a particle size from about 200 to about 2000 microns.
