PROBLEM TO BE SOLVED: To provide simulated feces enabling easy fouling evaluation by visualizing an adhesive portion onto a toilet bowl, and capable of reproducing a fouling property similar to feces. SOLUTION: A dye is dissolved and blended beforehand into an oil-and-fat portion and moisture, respectively, in a simulated feces substrate including the oil-and-fat portion, moisture and an organic/inorganic portion. In the simulated feces, at least one or more kinds of oily dyes and aqueous dyes having each different coloring region are blended respectively as the dye. The oily dye is Sudan II, and the aqueous dye is Methylene Blue. COPYRIGHT: (C)2008,JPO&INPIT
