Abstract:
A process for preparing an air freshener propolis solid composition comprising (A) a propolis mass and/or an extraction residue thereof having a surface adapted to absorb a surfactant, (B) water alone or a mixture of water with a water-soluble solvent capable of forming a hydrogen bond with water, (C) an anionic surfactant containing polyacrylate, and (D) a hydrophilic polymer compound, the subliming propolis solid composition containing, per 100 parts by weight of total of components (A) and (B), 0.01 to 25 parts by weight of component (C) and 0.1 to 50 parts by weight of component (D),the process comprising the steps in the order listed of:(1) preparing a solvent solution by dissolving a surfactant (C) in water alone or a mixture of water with a water-soluble solvent capable of forming a hydrogen bond with water (B) to obtain a solvent solution,(2) at a temperature of 15 to 200.degree. C., mixing the solution of step (1) with a propolis mass and/or an extraction residue thereof (A) to form a suspension, and then(3) adding and homogeneously mixing a hydrophilic polymer compound (D) to/with the dispersion of step (2) while the dispersion is maintained at a temperature of 0 to 200.degree. C. and allowing the mixture to stand and solidify into a solid composition.
