A container for releasing a microbiocide component into a liquid composition susceptible to unwanted microbial growth (LCMG) includes a LCMG impermeable casing separate and apart from an internal combustion engine filter housing, and having a hollow interior and at least one opening. A microbiocide component, for example, at least one LCMG-soluble microbiocide, as the only active material located in the hollow interior. At least one liquid permeable element, for example, a membrane member, is provided at or near an opening in the casing and is effective to provide for release of microbiocide component into the LCMG. Methods of releasing microbiocide component into LCMGs are also provided.

Controlled release of microbiocides

A container () for releasing a chemical additive () in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing () having a hollow interior and an additive composition () comprising at least one fluid material-soluble additive. The additive () is held within the container () by a least one fluid material-permeable element () provided at or near an opening () in the casing () and is effective to provide for release of additive(s) () into the fluid material. Methods of releasing additives () into fluid material are also provided.

A container for releasing a chemical additive into a fuel composition comprises a fuel-impermeable casing having a hollow interior and an additive composition comprising at least one fuel soluble additive. The additive is held within the container by at least one fuel-permeable element provided at or near an opening in the casing and is effective to provide for release of additive(s) into the fuel composition. Methods of releasing additives into fuel compositions are also provided.
