Title: Functional material with effect with visibly recognizable end point
Inventor: FUJITA MASAO
IPC: C09B67/02
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain a functional material which enables the end point of the efficacy of a drug to be visibly recognized, all the volatile drugs capable of dissolving an oil-soluble dye to be used, and the decrease in a drug to be recognized by the decrease in color by causing a volatile drug contg. an oil-soluble dye and a surfactant both dissolved therein to be carried by a carrier not dyeable with the dye. SOLUTION: A material which is not affinitive, i.e., is not dyed, with an oil-soluble dye is used as the carrier. Examples of the carrier are hydrophilic materials (e.g. cellulose beads) and waxes. When the volatile drug is present, it contains the oil-soluble dye dissolved therein and the surface of the carrier is covered with the drug; hence, the carrier 1 looks like colored. When the drug evaporates and the concn. of the oil-soluble dye becomes high, then the surfactant acts as a flocculant and causes the deposition and solidification of the dye 2 on the carrier surface not affective for an oil-soluble substance. Thus, the color of the dye 2 becomes unnoticeable and the carrier 1 exhibits its own color. Such a change in color enables the recognition of whether the efficacy of the drug still exists or not.
