CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national stage entry under 35 U.S.C. .sctn. 371 of PCT/IB99/01028, filed Jun. 4, 1999, which claims priority to EP 98870137.1 filed Jun. 15, 1998.
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.degree. 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.
The present invention relates to a process for the manufacture of a spray dried powder comprising: (a) forming a warm, stirred aqueous slurry comprising: inorganic salts, at least one binding agent and 0.001 to 20% by weight of capsules based on the weight of spray dried powder, said capsules containing benefit agents including at least perfume, and (b) spray drying the resultant slurry to form a spray dried powder, said capsules being such that: 1) more than 40% of the benefit agents remain encapsulated 60 minutes after dispersion thereof at 70.degree. C. in the slurry as defined in the "slurry survival test" in a sealed vessel without agitation; and 2) more than 30% of the benefit agents added for 15 minutes to an ambient slurry as defined in the "spray dry test" survive spray drying through a laboratory scale spray drier.
