Embodiment 4

[0030] Modified starches with emulsifying and emulsifying stabilizing capabilities, such as octenyl succinic acid starch, can carry the sesame oil droplets in the emulsion due to the hydrophobic properties of the starch modifier. The sesame oil remains entrapped in the modified starch until it dissolves in the aqueous solution due to thermodynamic factors, namely hydrophobicity and stabilization of the emulsion (due to steric hindrance). Example 4 Preparation of Modified Starch Encapsulating HIA Spice Granules

[0031] The following are non-limiting examples of suitable methods of preparing modified starch-encapsulated HIA perfume granules for use in the detergent compositions of the present invention.

Abstract

Modified starch encapsulated High Impact Accord (''HIA'') perfume particles. The particles consisting 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 mmHg, of 275 DEG C or 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 useful in laundry compositions.

Description

field of invention [0001] The present invention relates to encapsulated perfume particles, in particular to perfume components delivering high impact index (HIA) and detergent compositions containing these encapsulated perfume particles, especially granular detergents. Background of the invention [0002] Most consumers desire scented detergent products and expect fabrics and items washed with these products to also have a pleasant scent. In many parts of the world, hand washing is the main way of washing fabrics. When hand washing soiled fabrics, the user is always in contact with the wash solution and in close proximity to the detergent product used in it. Hand wash solutions can also create nasty odors when added to dirty clothes. It is therefore necessary and commercially beneficial to add fragrances to these products. Perfume additives make detergent compositions more pleasant to the consumer and in some cases perfumes impart a pleasant fragrance to treated fabrics. ...
