A method for reducing formation of deposits on a surface in contact with an aqueous system includes applying to the surface a composition comprising a polyoxypropylene-polyoxyethylene block copolymer and a biocide. The composition optionally may also include a dispersant.

Methods for reducing deposit formation on surfaces

Compositions and methods for cleaning metal and non-metal surfaces utilizing a nonionic surfactant and an enzyme are disclosed. A composition comprised of at least one nonionic surfactant and at least one enzyme and having a pH of between 6 and 9.5 is specifically disclosed. A method for cleaning a surface using this composition, and a method for cleaning a surface using a first composition comprising at least one nonionic surfactant and a second composition comprising at least one enzyme are also disclosed.

Composition and methods for cleaning surfaces

Synergistic antimicrobial combinations comprising 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one and a mixture of a chlorinated isocyanurate and a bromide compound are disclosed. Methods for inhibiting microbial growth using these synergistic antimicrobial combinations are also disclosed.

Synergistic antimicrobial combination of

A method for inhibiting microbial colonization of a surface in contact with an aqueous system is disclosed, which comprises adding to the system an amount of at least one compound including repeating ethylene oxide units.
