Abstract
A non-aqueous, single phase, non-thickened liquid air freshener or insecticidal composition having a flashpoint of greater than about 62° C. is provided. The composition contains: a) a polar solvent; b) up to about 10 wt % of a non-polar aliphatic hydrocarbon solvent; and c) a fragrance or an insecticide. The composition may be dispensed from a device having a chamber with at least one wall made of a material which enables a vapor of the composition to diffuse out of the chamber.
Claims14
An air freshener or insecticidal device comprising a chamber containing about 5 to about 50 grams of a composition, wherein the chamber comprises at least one permeable membrane wall comprising a material which enables a vapor of the composition to diffuse through the wall and out of the chamber, and wherein the composition is a non-aqueous, single phase, non-thickened liquid air freshener or insecticidal composition having a flashpoint greater than about 62° C. and comprising:
- a) a polar solvent;
- b) a non-polar aliphatic hydrocarbon solvent, which is present in amount up to about 10 wt %, based on the total weight of the composition;
- and
- c) a fragrance or an insecticide;
- wherein the polar solvent has an evaporation rate less than about 100 and the non-polar solvent has an evaporation rate less than about 16, both rates being based on a scale in which n-butyl acetate has an evaporation rate of 100.
