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.
