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.

First claim

What is claimed is:

1. A solid pressed air freshener and/or odor neutralizer comprising:
from about 40 wt. % to about 80 wt. % of a fragrance component, wherein the fragrance component comprises a fragrance and one of a starch or powder carrier;
a surfactant; and
a solidifier,
wherein said air freshener comprises greater than 10% fragrance and the surfactant and solidifier are in a ratio of greater than 1:1 on a percent weight basis.

2. The air freshener according to claim 1 wherein the fragrance component comprises a fragrance and a starch.

3. The air freshener according to claim 1 further comprising a disintegration aid.

4. The air freshener according to claim 1 further comprising an effervescence combination.

5. The air freshener according to claim 1 further comprising a coupler.

6. The air freshener according to claim 1 further comprising a high temperature stabilizer.

7. The air freshener according to claim 1 wherein the surfactant is a polyethylene oxide surfactant.

8. The air freshener according to claim 7 wherein said polyethylene oxide surfactant has a melting point greater than 30° C.

9. The air freshener of claim 1 wherein said surfactant is a C 8 to C 24 alcohol with from about 20-40 moles of ethoxylate.

10. The air freshener according to claim 1 wherein the surfactant is sodium lauryl sulfate.

11. The air freshener of claim 1 wherein said solidifier is polyethylene glycol having an average molecular weight of 4000.

12. The air freshener of claim 1 wherein said surfactant is present in an amount of from about 20-50 wt. %.

13. The air freshener of claim 1 wherein said solidifier is present in an amount of from about 15-40 wt. %.

14. An air freshener use solution comprising the solid pressed air freshener of claim 1 and water, wherein the use solution is formed by dissolving the solid pressed air freshener in the water.

15. The air freshener of claim 1 , wherein said powder carrier is sodium lauryl sulfate.

16. An air freshener composition comprising:
a fragrance component of from about 40-80 wt. %, wherein the fragrance component comprises a fragrance and one of a starch or powder carrier;
a surfactant of from about 20-50 wt. %; and
a solidifier of from about 15-40 wt. %,
wherein said fragrance component comprises up to about 30% by weight of fragrance and the ratio of surfactant to solidifier is greater than 1:1.

17. The composition of claim 16 wherein said fragrance component comprises a fragrance and a starch.

18. The composition of claim 16 wherein said fragrance component comprises a fragrance and a powder carrier.

19. The composition of claim 18 , wherein said powder carrier is sodium lauryl sulfate.
