Abstract
Provided herein are solid salt base or sugar base compositions for delivering encapsulated fragrance to textiles, and processes of making and using the compositions for treating textiles. It has been discovered that, during the manufacturing process, premixing a silicon compound and a salt base or sugar base before incorporating an encapsulated fragrance slurry to the salt base or sugar base significantly decreases the encapsulate breakage rate of the solid compositions. Solid encapsulated fragrance compositions prepared by the process allows consumers to experience a long-lasting freshness of their clothes after treating their clothes with the encapsulated fragrance compositions.
