In accordance with the present invention, it has been discovered that an additive which is substantially insoluble in, has low solubility in and/or is otherwise incompatible with a functional fluid, may be supplied to the functional fluid by use of a gel composition and/or a solid additive composition containing the additive, such that the functional fluid can receive the benefit of the supplied additive and/or contain levels of the additive not otherwise achievable by conventional delivery method due to the incompatibility of the additive with the functional fluid.
A method of passively delivering an active additive to a functional fluid, wherein the additive is substantially insoluble in, has low solubility in, or is otherwise incompatible with said functional fluid, comprising:
A gel composition wherein the gel is formed by a combination of:
An additive composition which is solid at room temperature comprising at least two additive components which are substantially insoluble or have low solubility in a functional fluid;
