Liquid Support
Agglomerating carrier materials in the presence of a granulation liquid with a carbohydrate content and subsequent incorporation of a liquid, such as a perfume oil, yields fluid-containing particles that, even at an elevated liquid loading, exhibit very good powder properties and reliably retain the incorporated liquid even in aggressive solid matrices. These fluid-containing particles may be used, for example, for fragrancing purposes.
1 . A fluid-containing particle, comprising a carrier material agglomerated with a granulation liquid, the granulation liquid comprising a carbohydrate or carbohydrate derivative, and the particle further comprising an incorporated liquid.
2 . The fluid-containing particle of claim 1 , wherein the incorporated fluid comprises:
(a) an odoriferous substance;
(b) a liquid detergent or cleaning agent;
(c) a liquid cosmetic ingredient;
(d) a liquid non-pharmaceutical additive or active ingredient; or
(e) a mixture of the above.
3 . The fluid-containing particle of claim 2 , comprising at least 5% by weight of an odoriferous substance.
4 . The fluid-containing particle of claim 1 , wherein the carrier material comprises an anionic carrier material.
5 . The fluid-containing particle of claim 4 , wherein the anionic carrier material comprises zeolite or phyllosilicate.
6 . The fluid-containing particle of claim 1 , comprising at least 30% by weight of zeolite or bentonite.
7 . The fluid-containing particle of claim 1 , comprising at least 10% by weight of a solid material added in crystal form, based on the total solids content of the particle.
8 . The fluid-containing particle of claim 1 , wherein the carrier material comprises a spray-dried material.
9 . The fluid-containing particle of claim 8 , wherein the spray-dried material comprises a tower powder.
10 . The fluid-containing particle of claim 1 , wherein the starch or starch derivative comprises:
(a) a cellulose or cellulose derivative;
(b) a starch or starch derivative;
(c) a mono-, oligo- or polysaccharide or a derivative thereof; or
(d) a mixture of the above.
11 . The fluid-containing particle of claim 1 , wherein the granulation liquid comprises at least 80% by weight of a solvent, based on the granulation liquid.
12 . The fluid-containing particle of claim 1 , comprising a coating.
13 . The particle of claim 12 , wherein the coating comprises a powder or a film.
14 . The fluid-containing particle of claim 12 , wherein the coating comprises a colored substance, a dye, a brightener, or a pigment.
15 . The fluid-containing particle of claim 12 , comprising a thermoplastic coating material.
16 . Fluid-containing particles according to claim 1 , having an average particle size of 0.1 to 2.0 mm.
17 . The fluid-containing particle of claim 1 , comprising a solid silicate, phosphate, urea, urea derivative, sulfate, carbonate, citrate, citric acid, acetate, or salts of an anionic surfactant.
18 . A detergent, cleaning agent, or conditioner comprising the fluid-containing particles of claim 1 .
19 . A method of fragrancing a room, vehicle, or closet, comprising contacting or exposing a room, vehicle, or closet in need of fragrancing with an effective amount of particles according to claim 1 , wherein the particles comprise an odoriferous substance.
20 . A method of fragrancing objects, comprising contacting or exposing an object in need of fragrancing with an effective amount of particles according to claim 1 , wherein the particles comprise an odoriferous substance.
