Abstract
The present invention relates to a controlled release carrier system that can be incorporated into rinse-off application products containing at least one surfactant such as heavy duty liquids (HDL), Rinse Cycle Fabric Softeners (RCFS), Shampoos, Hair Conditioners, Shower Gels, cleansing products, and that enhance deposition of lipophilic active materials like fragrance, fine perfumes, flavors and other volatile compounds onto a surface. The fragrance composition is encapsulated within a shell comprising a silicon-containing material and the shell has a mean diameter size which is lower than 30 micrometer. The surfactant composition containing the fragrance composition is washed off and the fragrance is progressively released.
