Solid air freshener

Abstract

The present invention relates to a solid pressed air freshener and odor neutralizer composition which can include greater than 10% fragrance. The air freshener comprises a fragrance; preferably the fragrance is impregnated within a water soluble substrate made from a foamed vegetable starch, a surfactant and a solidifier. The solid formulations break down easily in the presence of water and may be sprayed, within the area to be freshened.

What is claimed is: 
     
         1 . A solid pressed air freshener and/or odor neutralizer comprising:
 a fragrance component, a surfactant and a solidifier, wherein said air freshener comprises greater than 10% fragrance.   
     
     
         2 . The air freshener according to  claim 1  wherein the surfactant and solidifier are in a ratio of greater than 1:1 on a percent weight basis. 
     
     
         3 . The air freshener according to  claim 1  wherein the fragrance component includes a fragrance and a starch. 
     
     
         4 . The air freshener according to  claim 1  further comprising a disintegration aid. 
     
     
         5 . The air freshener according to  claim 1  further comprising an effervescence combination. 
     
     
         6 . The air freshener according to  claim 1  further comprising a coupler. 
     
     
         7 . The air freshener according to  claim 1  further comprising a high temperature stabilizer. 
     
     
         8 . The air freshener according to  claim 1  wherein the surfactant is a polyethylene oxide surfactant. 
     
     
         9 . The surfactant according to  claim 8  wherein said polyethylene oxide surfactant is has a melting point greater than 30° C. 
     
     
         10 . The surfactant of  claim 8  wherein said surfactant is a C 8  to C 24  alcohol with from about 20-40 moles of ethoxylate. 
     
     
         11 . The air freshener according to  claim 1  wherein the surfactant is sodium lauryl sulfate. 
     
     
         12 . The solidifier of  claim 1  wherein said solidifier is polyethylene glycol having an average molecular weight of 4000. 
     
     
         13 . The air freshener according to  claim 3  wherein said starch fragrance composition is present in an amount of from about 35-60 wt. %. 
     
     
         14 . The air freshener of  claim 1  wherein said surfactant is present in an amount of from about 20-50 wt. %. 
     
     
         15 . The air freshener of  claim 1  wherein said solidifier is present in an amount of from about 15-40 wt. %. 
     
     
         16 . An air freshener use composition comprising the composition of  claim 1  and water, wherein the solid air freshener composition is dissolved. 
     
     
         17 . An air freshener composition comprising:
 a fragrance component of from about 40-80 wt. %;   a surfactant of from about 20-50 wt. %;   a solidifier of from about 15-40 wt. percent wherein said fragrance component comprises up to about 30% by weight of fragrance.   
     
     
         18 . The air freshener of  claim 17  wherein said fragrance component comprises a combination of fragrance and starch. 
     
     
         19 . The air freshener of  claim 17  wherein said fragrance component comprises a fragrance and a surfactant. 
     
     
         20 . The air freshener of  claim 17  wherein the ratio of surfactant to solidifier is greater than 1:1.
