MP GOKYO FOOD&CHEMICAL CO.,LTD List of Products and Services

The substances extracted from plant seeds, fruit shells, leaves, roots, etc., which can be used to turn animal hides into leather, are collectively referred to as "tannins" or "plant tannins." Among tannins, tannic acid is derived from gallnuts harvested from plants in the Anacardiaceae family and from oak galls harvested from plants in the Fagaceae family. Our company has been selling various types of tannic acid as a manufacturer of tannic acid and its derivatives for several decades. Tannic acid is used in industrial applications as a dye fixative for nylon, preservatives, boiler cleaning agents, rust inhibitors, and ink materials, and it also has a track record as an antioxidant and preservative in food applications. 【Properties】 ■ Easily soluble in water, alcohol, acetone, etc., and poorly soluble or insoluble in ether, chloroform, petroleum ether, benzene, etc. ■ Astringent properties ■ Reacts with proteins ■ Reacts with metals ■ Reducing power (antioxidant properties) ■ Deodorizing effect (adsorbs amines, etc.) ■ Interaction with dye molecules ■ Does not show a melting point, decomposes at 210°C, producing pyrogallol and carbon dioxide.

"Gallic acid derivatives" can be used as antioxidants, colorants, canning agents, and for pharmaceutical applications as antioxidants! 【Properties of Gallic Acid】 ■ Poorly soluble in water. Soluble in alkaline solutions. ■ Soluble in alcohol. ■ Melting point is 258–263°C. ■ Has antioxidant effects. 【Properties of Propyl Gallate】 ■ Poorly soluble in water. Soluble in alcohol. ■ Melting point is 150°C. ■ Has antioxidant effects. The catalog can be downloaded from the "Special Site/Tannic Acid Products." *For more details, please refer to the PDF materials or feel free to contact us.

Pyrogallol has been used for a long time as a pharmaceutical raw material and a photographic developing agent. In recent years, "pyrogallol" has been used as a sensitizer raw material for photoresists, antioxidants, chelating agents, and enzyme absorbents. 【Properties】 Chemical formula: 1,2,3-Trihydroxybenzene Content: 99.5% or more ■ It has strong reducing properties, rapidly absorbing oxygen from the air and changing color. Particularly in alkaline aqueous solutions, it actively absorbs oxygen from the air. ■ It reduces metal salts to precipitate metals. ■ It produces a red color with ferric chloride, a blue color with ferric sulfate containing ferric chloride, and a white color with lead acetate, resulting in precipitation. 【Applications】 Chelating agents, raw materials for printing inks (photographic), antioxidants, vulcanization suppressants for rubber, resin stabilizers, applications for metal ion absorption, dyeing raw materials, oxygen absorbents, and de-gumming agents. *For more details, please refer to the PDF document or feel free to contact us.

We utilize cutting-edge chemical technology and specialized expertise accumulated over many years to plan and propose functions tailored to the characteristics of products in a wide range of fields, including printing inks, paints, textile processing agents, flat panel displays, packaging materials, and molding resins. We would like to introduce the 'industrial chemicals' that Sumitomo Pharma Food & Chemical Co., Ltd. has manufactured and imported. 【Main Products】 ■ Tannic acid derivatives ■ Natural polysaccharides ■ Organic acids ■ Others

MP Five Co., Ltd.'s "Coating Materials and Industrial Chemicals Division" provides raw materials for inks and paints that protect automobiles, mobile phones, and home appliances from scratches, dirt, and friction while also imparting functionality and stability. Additionally, it sells coating materials that smooth the surfaces of flat panel displays and enhance their anti-soiling properties and toughness. Our coating technology is also effective in packaging materials and molded parts, enhancing the adhesive effects between resin and resin or resin and metal. Furthermore, we offer a unique range of industrial chemicals that contribute to various chemical product fields, as well as liquid filtration systems used for foreign matter removal during the manufacturing of chemical products and food. Here are the main products handled in the "Coating Materials and Industrial Chemicals Division": 【Main Products】 ■ Thickeners, emulsifying stabilizers, binders ■ Acetylene derivatives, cellulose derivatives ■ Surface modifiers (fine powder) ■ Resins ■ Surfactants ■ Tannic acid derivatives ■ High-performance silicones ■ Liquid filtration filters ■ Other additives *For more details, please refer to the PDF materials or feel free to contact us.
