A transparent gel air freshener and method of preparing the same. The gel composition comprises an aqueous gel, a fragrance, a surfactant and a co-solvent. The gel is transparent and free from visible particles and inhomogeneities, has a uniform texture and a continuous structure, and includes volatile scented components. The gel is capable of suspending solids such as botanicals therein for decorative effect. The method provides for preparation of a such a gel air freshener, including the suspension of botanicals therein, while maintaining the clarity, texture, and structure of the gel. The method includes the steps of preparing a gel composition and cooling the gel composition. Botanicals may be added to the gel composition when it has gelled enough to support the botanicals on the gel surface.

[ What is claimed is:] [1.] A method for making a transparent air freshener comprising the steps of:mixing together about 0.001-15 wt % potassium citrate as a cross-linking agent, an aversive agent, about 0-0.2 wt % color and deionized water to form a first solution, the mixing step continuing until the first solution is clear;dispersing into the first solution about 0.05-10 wt % modified polysaccaride gum as a gelling agent to form a dispersion;heating the dispersion to above 60.degree. C. and stirring the dispersion until the dispersion is clear;after the dispersion is clear, cooling the dispersion to about 60.degree. C.;mixing together an initial mixture of about 0.5-20 wt % nonionic surfactant, about 0-3.0 wt % SD alcohol, about 0.1-30 wt % dipropylene glycol as a co-solvent and about 0.1-15 wt % fragrance until the initial mixture is clear;mixing the initial mixture with the dispersion at a temperature greater than about 55.degree. C. to form a resulting mixture and then cooling the resulting mixture until the resulting mixture becomes a clear mixture;pouring the resulting mixture into a transparent container; andchilling the transparent container, said phase being free from clouding with resulting mixture to form a transparent, homogenous gel having one phase in the container;the fragrance being present in an amount to provide a vapor pressure at 20.degree. C. of not more than 0.1 mm Hg, the nonionic surfactant being in an amount to form the transparent gel having one phase, the co-solvent being in an amount to moderate evaporation of the fragrance so that the transparent gel acts to freshen a room by evaporation of the fragrance, said fragrance being released over a period of at least two weeks.
