Abstract

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.

First claim

Opening claim text (preview).

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.
