Claims32
A process for absorbing moisture and/or malodor, and providing a fragrance to the surrounding ambience comprising:
- (a) providing a delivery vehicle comprising an enrobement material, a fragrance, and a fixative, wherein the delivery vehicle is a free flowing powder;
- (b) combining the delivery vehicle with an absorbent material to form a mixture;
- and
- (c) contacting the mixture of (a) and (b) with a moisture and/or a malodor source.
A fragranced delivery vehicle comprising a fragrance composition dispersed in a fixative and an enrobement material, wherein the fragrance composition, fixative, and enrobement material, when combined, form a free flowing powder.
A composition for absorbing moisture and/or malodor and imparting a fragrance to a surrounding environment comprising from about 30% (wt) to about 98% (wt) of an absorbent material, from about 1% (wt) to about 20% (wt) of a delivery vehicle, wherein the deliver vehicle comprises, in a free flowing powder, a fragrance, a fixative, and an enrobement material, and from about 0% (wt) to 50% (wt) of fillers and binders.
A process for providing a fragrance and absorbing moisture and/or malodor to a substrate comprising:
- (a) providing a free flowing powder comprising a fragrance composition, a fixative, an enrobement material, and an absorbent material;
- and
- (b) contacting the free flowing powder with the substrate.
A fragrancing and moisture and/or malodor suppression system comprising:
- (a) a free flowing powder comprising a fragrance composition, a fixative, and an enrobement material combined with an absorbent material;
- (b) a housing means for housing the free flowing powder including the absorbent material;
- and
- (c) a vapor permeable outer material disposed about the housing means, wherein moisture and malodor from a surrounding environment may diffuse through the outer material and into the free flowing powder and fragrance from the free flowing powder may diffuse through the outer material into the surrounding environment.
