The present invention relates to a microcapsule exhibiting desirable sustained-release properties, which microcapsule comprises a core material comprising an active ingredient encapsulated within a silica shell, characterized in that the outer surface of such silica shell has a layer of a metal selected from Group 2a, Group 8, Group 2b or Group 3a of the Periodic Table bound thereto. In other aspects this invention relates to a method of making such a microcapsule; a pesticidal composition comprising microcapsules comprising a pesticidal active ingredient and a suitable carrier; and to a method of controlling pests comprising applying an effective amount of such a pesticidal composition to a locus where pests are or are expected to be present.

Sustained release silica microcapsules

A method of controlling the deposition of silica containing scales and their adhesion to surfaces in contact with an aqueous system is disclosed which comprises adding to the aqueous system about 1-500 ppm of a water-soluble or dispersible hydrophobically modified polyether polymer. Exemplary hydrophobically modified polyether polymers include alkylene oxide hydrophilic backbone repeat units and hydrophobic groups that may be attached to the backbone at a variety of locations such as 1) at the ends of the backbones, 2) either regularly or randomly spaced along the backbone length, or 3) as linking groups to link two or more portions of the backbone together.

Methods for controlling silica scale in aqueous systems

The present invention is directed to a gas turbine cleaner. The composition of the present invention includes a glycol alkyl ether compound, an alkoxylated surfactant with an alkyl chain length of from about 3 to 18 carbons and a metal corrosion inhibitor component.
