Perfumed household products and methods for preserving perfume integrity and extending fragrance life

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.

 iii. water; and 
   b. a plastic container constructed from at least about 80 wt. % hydrophilic perfume compatible materials, wherein said aqueous composition is contained in said plastic container.   
   
   
       2 . The product of  claim 1  wherein said hydrophilic perfume compatible materials is selected from the group consisting of: high density polyethylene, low density polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyethylene-co-vinyl alcohol, fluorinated polymer, acrylonitrile-methyl acrylate copolymer, and mixtures thereof. 
   
   
       3 . The product of  claim 1  wherein said aqueous composition comprises from about 0.05 wt. % to about 0.2 wt. % of said perfume. 
   
   
       4 . The product of  claim 1  wherein said product further comprises a substrate, said substrate is impregnated with said aqueous composition. 
   
   
       5 . The product of  claim 4  wherein said substrate is a non-woven wet-wipe. 
   
   
       6 . The product of  claim 1  wherein said boiling point is greater than about 250° C. 
   
   
       7 . The product of  claim 1  wherein said boiling point is greater than about 280° C. 
   
   
       8 . The product of  claim 1  wherein said perfume contains at least about 40 wt. % of one or more hydrophilic perfume ingredients. 
   
   
       9 . The product of  claim 8  wherein said boiling point is greater than about 250° C. 
   
   
       10 . The product of  claim 8  wherein said hydrophilic perfume compatible materials is selected from the group consisting of: high density polyethylene, low density polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyethylene-co-vinyl alcohol, fluorinated polymer, acrylonitrile-methyl acrylate copolymer, and mixtures thereof. 
   
   
       11 . The product of  claim 1  wherein said perfume contains at least about 70 wt. % of one or more hydrophilic perfume ingredients. 
   
   
       12 . The product of  claim 11  wherein said boiling point is greater than about 250° C. 
   
   
       13 . The product of  claim 11  wherein said boiling point is greater than about 280° C. 
   
   
       14 . The product of  claim 11  wherein said hydrophilic perfume compatible materials is selected from the group consisting of: high density polyethylene, polypropylene, and mixtures thereof. 
   
   
       15 . The product of  claim 1  wherein said one or more hydrophilic perfume ingredients are selected from the group consisting of: ethyl vanillin; isoeugenyl acetate; heliotropine diethyl acetal; 2H-1,5-Benzodioxepin-3(4H)-one, 7-methyl-; 4-(4-Hydroxyphenyl)butanone-2; vanillin isobutyrate; helional; cashmeran; piperonyl acetone; methyl beta-naphthyl ketone; methyl dihydrojasmonate; lyral; and mixtures thereof. 
   
   
       16 . The product of  claim 1  wherein said aqueous composition comprises from 0.05 wt. % to about 0.2 wt. % perfume, from about 0.1 wt. % to about 20 wt. % of cyclodextrin, and from about 0.15 wt. % to about 20 wt. % of a cyclodextrin-compatible perfume. 
   
   
       17 . A method of preserving perfume integrity and extending fragrance life in household cleaning, fabric treatment or deodorizing products comprising:
 a. providing an aqueous composition comprising from about 0.1 wt. % to about 30 wt. % of a surfactant, and from about 0.003 wt. % to about 5 wt. % of a perfume, wherein said perfume contains at least about 10 wt. % of one or more hydrophilic perfume ingredients having a Clog P of less than about 3 and a boiling point greater than about 200° C.; and   b. packaging said product in a plastic container constructed of at least about 80 wt. % hydrophilic perfume compatible materials.   
   
   
       18 . The method of  claim 17  wherein said product further comprises a substrate, said substrate is impregnated with said aqueous composition. 
   
   
       19 . The method of  claim 17  wherein said perfume contains at least about 40 wt. % of one or more hydrophilic perfume ingredients have a Clog P less than about 3 and a boiling point greater than about 280° C. 
   
   
       20 . The method of  claim 17  wherein said perfume contains at least 70% of one or more hydrophilic perfume ingredients having a Clog P of less than about 3 and a boiling point greater than about 280° C.
