Abstract: [Problem to be Solved] An object of the present invention is to provide an aqueous antimicrobial composition which exhibits excellent antibacterial and antifungal activities even at a low concentration and has high safety, low skin irritation, and excellent long-term stability. [Solution] Aqueous antimicrobial compositions comprising two or more compounds selected from (a) benzoic acid or a salt thereof, (b) ?-gluconolactone, (c) ketonic acid or a salt thereof, and (d) sorbic acid or a salt thereof; and at least one or more dicarboxylic acid represented by General Formula (I) or a salt thereof.

Abstract: Provided herein is a disclosure that blending a dicarboxylic acid with a ketonic acid, used as a preservative in a end-use formulation, such as a personal care product, can mitigate the discoloration of the end-use formulation which is caused by an elevated pH in the end-use formulation or in end-use formulations which have been exposed to elevated temperature.

Abstract: A process progress display device includes a stencil making block which displays a progress status of a stencil making process, a printing block which displays a progress status of a printing process, a stencil making stop bar which displays whether or not an entire process is to be stopped at an end of the stencil making process, and a printing stop bar which displays whether or not the entire process is to be stopped at an end of the printing process.
