Condensed phosphate -the first product we succeed in producing phosphate industrially in Japan| Rin Kagaku Kogyo

We use phosphoric acid produced using our own custom dry process as the main raw material, which means that we can guarantee high quality and safety. In the area of food additives in particular, we boast the best quality in Japan, thanks to our technology and experience that we have cultivated over many years. Most phosphate is in powdered form, but we also handle some products in granular form that have excellent solubility.

Other salts (Nankarin and Rintop)

Nankarin S-1

Overview	This product is a water treatment agent for which various phosphates have been blended to suit the application. When used to soften or disperse water for industrial applications, this product offers even better advantages when it is used together with several other types of phosphates, taking into account the desired pH for the objective.
Applications	Paper manufacturing/pulp pitch regulation, metal cleaning, fabric scouring, dispersal agents for boosting detergency power, peroxide stabilizers
Shipping option	Paper bag with polyethylene inner lining: 25kg net

Nankarin SH

Overview	Nankarin SH has been improved so that it takes less time to dissolve. We have developed this superior condensed phosphate while still retaining the properties of phosphate, such as its dispersive properties, its solubility in supersaturated solutions and its ability to sequester metal ions, soften hard water, and prevent corrosion of metal surfaces.
Applications	Water treatment agent for the fabric, dyeing, paper and pulp industries; reinforcing agent for surfactants; regulator for ore flotation liquids; viscosity lowering agent for drilling mud
Shipping option	Paper bag with polyethylene inner lining: 25kg net

Rintop 100

Overview	This is a granular product that addresses the caking problem due to the absorbency of acid hexametaphosphate soda, as well as the complexity of handling it.
Applications	Water treatment agents, bonding agents for heat resistant materials
Shipping option	Cardboard box with polyethylene inner lining: 12.5kg net
