Business Overview
Contributing to the Development of Industry and SocietyThe source of NISSO's diverse product lineup is our chlor-alkali products, centered on caustic soda and chlorine, which we have been manufacturing and supplying since our founding in 1920. A longside the growth of domestic industry, we have expanded, our product variations, and today we supply a wide range of industrial sectors.
Additionally, amid growing social interest in environmental conservation and safety, we provide products that support clean and secure living. The applications of these products have expanded across various fields, from preventing toilet odors to preventing exterior wall stains and preventing microbial contamination of industrial products.
Going forward, we will continue to leverage our proprietary technologies cultivated over many years, focusing on further improving product quality and increasing added value while ensuring stable supply, contributing to the development of industry and society.
The law requires that heavy metals, mainly lead, contained in fly ash generated during incineration at garbage incinerators be insolubilized. HIDION fixates and insolubilizes heavy metals in fly ash through its chelating effect, demonstrating high treatment performance.

Main Products
-
Caustic soda
Caustic soda is a strongly alkaline substance produced by the electrolysis of salt water.
It is also a product that we have offered since the company was founded, and its applications as a basic chemical are extensive.
From industrial applications such as petroleum refining, aluminum smelting, and wastewater treatment to the manufacturing of paper, textiles, and detergents, it is widely used for everyday items and is essential for industry. -
Phosphorus oxychloride
Phosphorus oxychloride is a phosphorous compound used in many industrial fields.
It is used as a raw material for flame retardants that are added to plastics and chemical fibers to make them resistant to fire, plasticizers that give them flexibility, and also an ingredient in fragrances, pesticides, and pharmaceuticals. -
Uroliths prevention agent for toilets
TAKE-ONEUroliths, which cause unpleasant odors in urinals, are formed when urea contained in urine reacts with bacteria, turning alkaline and resulting in the formation of calcium carbonate and other substances. TAKE-ONE prevents the formation of uroliths by keeping the trap portion of urinals slightly acidic through the effects of solid acid, its active ingredient.
