First claim
Opening claim text (preview).
What is claimed is: 1. A starch perfume delivery vehicle, comprising a starch matrix comprising, a perfume, and a lipophilic phosphate ester; wherein the lipophilic phosphate ester precipitates from the perfume to form a microencapsulate within said starch matrix and the perfume is miscible with the lipophilic phosphate ester prior to the forming of the microencapsulate. 2. The starch perfume delivery vehicle of claim 1 , wherein the starch comprises dextrin, pullulan, tapioca starch, starch acetate, maize starch, hydroxypropyl di-starch glycerol, hydroxyethyl starch, carboxymethyl starch, carboxyethyl starch, starch-2-hydroxypropyl citrate, starch sodium octenyl succinate, octenylsuccinic acid anhydride starch, or a combination thereof. 3. The starch perfume delivery vehicle of claim 2 , wherein the lipophilic phosphate ester comprises a phosphate monoester, a phosphate diester, or a combination thereof. 4. The starch perfume delivery vehicle of claim 3 , wherein the lipophilic phosphate ester comprises has an acid value of about 180 mg KOH/g phosphate ester to about 450 mg KOH/g phosphate ester. 5. The starch perfume delivery vehicle of claim 3 , wherein the lipophilic phosphate ester comprises an R-group having a carbon chain length of 6 to 18 carbons. 6. The starch perfume delivery vehicle of claim 5 , wherein the R-group is a C8 to C10 linear alkyl chain. 7. The starch perfume delivery vehicle of claim 3 , wherein the lipophilic phosphate ester comprises an octyl phosphate ester. 8. The starch perfume delivery vehicle of claim 7 , wherein the starch comprises an octenylsuccinic acid anhydride modified starch.
