Abstract
Abstract Modified starch encapsulated High Impact Accord (HIA) perfume particles are disclosed. The particles consist of a modified starch and perfume oil encapsulated by the starch and comprised of at least two HIA perfume ingredients which have a boiling point at 760 mm Hg, of 275° C. of lower, a calculated ClogP of 2.0 or higher, and an odor detection threshold less than or equal to 50 parts per billion (ppb). The encapsulated perfume particles are particularly useful in laundry compositions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
An encapsulated perfume particle comprising: a) a water-soluble modified starch solid matrix, wherein the modified starch comprises a starch raw material that has been modified by treatment of the starch raw material with octenyl-succinic acid anyhydride; b) a perfume oil encapsulated by the solid matrix of the modified starch, comprising at least 40% by weight of at least 2 High Impact Accord (“HIA”) perfume ingredients, each of said perfume ingredient having (1) a boiling point at 760 mm Hg, of 275° C. or lower, (2) a calculated CLogP of 2.0 or higher, and (3) an odor detection threshold (“ODT”) less than or equal to 50 ppb and greater than 10 ppb; wherein the perfume particle begins to release the encapsulated perfume immediately upon addition to water.
Claim 2
Dependent Claim
