Official abstract text for this publication.
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.
