Abstract: The present invention relates to a fragrance delivery system for use in laundry detergent compositions including rinse-added and dryer-added fabric conditioning compositions which provides a long lasting “freshness” or “clean” scent to fabric. The compositions described herein deliver highly fabric substantive linear acetal and/or ketal pro-fragrances to the fabric surface during laundering wherein the pro-fragrances release their fragrance raw materials over a period of up to two weeks. The present invention also relates a method for delivering a pleasurable scent to fabric which has a lasting freshness quality by contacting the fabric with a laundry detergent composition which comprises the fragrance-releasable pro-fragrances.
Abstract: The present invention relates to bleaching, pre-soak, pre-treatment, and laundry detergent compositions comprising:

Abstract: Coated French fried potatoes which maintain crispness for at least about 10 minutes. The French fries have at least a 0.1 mm starch-based surface coating and Texture Value of at least about 170 after an extended holding time. The holding time is a measurement based on (1) 4 minutes holding under a heat lamp. (2) 3 minutes holding under a heat lamp in Foodservice serving bags and (3) at least 3 minutes holding in a closed carry-out bag. The par-fries have specific properties which, upon oven-finishing, deliver a unique texture. The coated oven-finished French fries have about 28% to about 50% bulk moisture and from about 8% to about 25% total fat.
The par-fried potato strips used to prepare the oven-finished French fried potatoes are coated with a starch suspension. The coating has a low water solubility starch fraction as one of its ingredients. The low water solubility starch fraction has a water solubility index of less than about 30%.
