Abstract
Stable odor controlling compositions, methods for incorporating the compositions, and disposable absorbent articles, which release perfume and subsequently are able to minimize odor caused from bodily fluids via the presence of an oil-in-water emulsion that serves as a carrier and preservation system for the perfume. The stable odor controlling emulsion compositions include an oil-in-water emulsion comprising: a) an aqueous phase comprising a modified starch and water; b) an oil phase comprising a perfume; c) an effective amount of a rheology modifier; d) an effective amount of a co-surfactant; and e) an effective amount of an antimicrobial agent; wherein said emulsion composition is applied to said article in the form of stable emulsion droplets having an median size of less than about 1 μm and dries to form a discontinuous film.
