PURPOSE:To diffuse a sufficient aroma until the use is completed while the aroma force value is not weak even when the time passes by making different the inclusion ratio and type of the aroma of respective layers with a liquid- shaped aroma agent composition in which two layers or above of a water layer and an oil layer are mutually superimposed. CONSTITUTION:The water layer part of a present invention composition is composed of water, an interfacial active agent and an aroma and an oil layer part is composed of a solvent and the aroma. As the solvent, at the time of the solvent which is insoluble to the water, odorless or a little odor, the special limit is not executed. To the water layer part and the oil layer part, additives such as a coloring matter, a defoaming agent, an oxidation inhibitor, etc., may be added besides the above-mentioned necessary component. Ordinarily, the water layer or the oil layer with the highest aroma adding ratio is made into the lowest layer and the water layer or the oil layer is superimposed in the higher order of the aroma concentration. Thus, since the water layer and the oil layer are alternately superimposed, the aroma hardly moves to other layer by the concentration difference and the aroma can be diffused sufficiently over one month. |
