Abstract
Household cleaning, fabric treatment, or deodorizing products and methods of preserving the integrity of hydrophilic perfume ingredients and extending fragrance life are disclosed. The product and method include an aqueous composition containing a surfactant and a perfume having a substantial proportion of hydrophilic perfume ingredients with a Clog P of less than about 3 and a boiling point greater than about 200° C. The aqueous composition may be contained in plastic containers constructed of hydrophilic perfume compatible materials. The invention preserves perfume integrity by decreasing migration of hydrophilic perfume ingredients into and/or transmission through plastic containers and extends fragrance life once the hydrophilic perfume ingredients are deposited onto a surface.
