ABSTRACT:
Two associated air treatment compositions are formulated such that when used together they produce a constant emanating composition throughout the life of an air treatment dispenser of the wick type (dispenser). Composition I comprises components (at least two active agents) in their respective intended concentrations and is used to impregnate the evaporation surface and/or wick of the dispenser. Composition II comprises the same components (at least the same two active agents) as the first composition. However, the concentrations of the components in Composition II with respect to Composition I are adjusted such that a constant emanating composition is maintained. The relationship between Composition I and II can be described by equation ##EQU1## where ##EQU2## is composition II and ##EQU3## is composition I. Coefficients c.sub.i can be calculated based on quantitative analysis of composition I and II by means known in the art. Composition II serves as a replenishing fluid, typically provided in a reservoir, with which the wick is in contact.
