Perfume compositions

Abstract

A perfume composition for improved release from a cyclodextrin complex, wherein the perfume composition includes 10% or more, by weight of the perfume, of one or more perfume raw materials having: a cyclodextrin complex stability constant of about 3.0 or less, a C log P of about 2.5 or less; and a weight average molecular weight of about 200 Daltons or less.

What is claimed is: 
     
         1 . A cyclodextrin complex, comprising a cyclodextrin and a perfume comprising perfume raw materials, wherein 10% or more, by weight of the perfume, of the perfume raw materials have:
 a cyclodextrin complex stability constant of about 3.0 or less, a C log P of about 2.5 or less; and   a weight average molecular weight of about 200 Daltons or less;   wherein the perfume is complexed with cyclodextrin particles having a moisture level of less than about 10%, by weight of the cyclodextrin particles.   
     
     
         2 . The cyclodextrin complex of  claim 1 , wherein the cyclodextrin comprises hydroxypropyl alpha-cyclodextrin, hydroxypropyl beta-cyclodextrin, methylated-alpha-cyclodextrin, methylated-beta-cyclodextrin, or a combination thereof. 
     
     
         3 . The cyclodextrin complex of  claim 1 , wherein the percent of the perfume that is complexed with the cyclodextrin is about 75% or more. 
     
     
         4 . The cyclodextrin complex of  claim 1 , wherein the perfume raw materials are selected from the group consisting of: beta gamma hexanol; cis 3 hexenyl acetate; ethyl-2-methyl butyrate; amyl-acetate; vanillin; anethole; methyl isoeugenol; guaiacol; floralol; 2,6-nonadien-1-ol; coumarin; and a combination thereof. 
     
     
         5 . The cyclodextrin complex of  claim 1 , wherein 10% or more of the perfume raw materials also have an Odor Detection Threshold of about 7 or more −log molar concentration. 
     
     
         6 . The cyclodextrin complex of  claim 1 , wherein about 20% to about 100%, by weight of the perfume, of the perfume raw materials have: a complex stability constant of about 3.0 or less, a C log P of about 2.5 or less; and a weight average molecular weight of about 200 Daltons or less. 
     
     
         7 . The cyclodextrin complex of  claim 1 , wherein the perfume raw materials have a complex stability constant of about −1.5 to about 2.5. 
     
     
         8 . A perfume comprising perfume raw materials, wherein 20% or more, by weight of the perfume, of the perfume raw materials, are selected from the group consisting of: ethyl-2-methyl butyrate; beta gamma hexanol; iso amyl acetate; amyl acetate; cis-3-hexenyl acetate; gamma-octalactone; ethyl vanillin; vanillin; benzaldehyde; dimethyl anthranilate; iso-eugenyl acetate; canthoxal; 3,6-nonadien-1-ol, triplal; and combinations thereof. 
     
     
         9 . The perfume of  claim 8 , wherein the perfume raw materials are selected from the group consisting of ethyl-2-methyl butyrate; beta gamma hexanol; iso amyl acetate; amyl acetate; cis-3-hexenyl acetate; gamma-octalactone; ethyl vanillin; vanillin; benzaldehyde; and combinations thereof. 
     
     
         10 . The perfume of  claim 8 , wherein the perfume is part of a cyclodextrin complex, and wherein the percent that is complexed with the cyclodextrin is about 75% or more.
