"IC Zinc" is a wetting agent that can be used on peaches and nectarines. Zinc ions have a bactericidal effect by penetrating the bodies of pathogens and inhibiting their enzymatic systems, while zinc oxide generates reactive oxygen species when exposed to ultraviolet light, which powerfully decomposes pathogens through a photocatalytic action. The bactericidal action is primarily due to metal ions, similar to copper agents, and the risk of developing resistant bacteria is extremely low. It is an inorganic bactericide that can be used during the growth period and has no restrictions on the number of days before harvest. 【Features】 ■ Effective against bacterial diseases ■ Inorganic bactericide that can be used during the growth period ■ No restrictions on the number of days before harvest ■ Active ingredient: Zinc oxide 97.0% ■ Appearance: White to off-white wettable powder *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Chokitsu Powder" that we handle. Chokitsu is one of the fragrant citrus fruits cultivated in Sukumo, Kochi Prefecture, and has long been cherished locally as vinegar orange. It is characterized by its mild acidity and refreshing aroma. Due to its distinct scent, it allows for product differentiation from mandarin oranges and yuzu. It is cultivated in the mountains where pesticides are used as little as possible, and pesticides from other crops do not drift. 【Features】 ■ Most Chokitsu products are made using fruit juice, while Chokitsu powder is a rare product. ■ Its distinct aroma allows for product differentiation from mandarin oranges and yuzu. ■ Cultivated in the mountains with minimal pesticide use and no drift from other crops. ■ Utilizes parts that would normally be discarded during juicing. *For more details, please download the PDF or feel free to contact us.

• Food ingredients (powder)

"Shimonko Light" is a white powder for deodorants that has a unique layered structure. It physically captures bad odors in the "interlayers" where crystals overlap and traps them inside. The ions in the interlayers and surface layer can bind with odor components both physically and chemically, making it possible to suppress the re-release of bad odors. It exhibits a high deodorizing effect against hydrogen sulfide, ammonia, and others, significantly reducing the "re-release" of absorbed odors compared to activated carbon. [Features] ■ Physically captures and traps bad odors inside due to its unique layered structure ■ Adsorbs odor components from both physical and chemical perspectives ■ Capable of controlling particle shapes such as hexagonal prisms and nanoparticles ■ Exhibits a high deodorizing effect against hydrogen sulfide, ammonia, and others ■ Significantly suppresses the "re-release" of absorbed odors compared to activated carbon *For more details, please download the PDF or feel free to contact us.

• Deodorizing and anti-odor products

"QC2-S" is a highly hygroscopic calcium oxide with small particles and rapid reaction properties. Compared to our conventional products, it has a D50 of 3.2μm, making it a fine particle that supports a wide range of applications, including water absorption and heat generation functions. We also handle calcium oxide that meets food additive standards and pharmaceutical use. The content is 20kg, and the packaging consists of an inner bag made of aluminum and an outer box made of cardboard. 【Features】 ■ Small particles with rapid reaction ■ D50: 3.2μm, Dmax: less than 23.5μm ■ Supports water absorption and heat generation functions *For more details, please download the PDF or feel free to contact us.

"Slalric" is a high-concentration calcium hydroxide for slurry that is surprisingly smooth despite its high concentration. It features excellent dispersion when dissolved in water and has high dispersibility that makes it resistant to settling over time. It maintains low viscosity even at a high concentration of 50% w/w. Since the main component is slaked lime, there is no need to handle hazardous materials or toxic substances. It is provided in powder form, allowing for concentration adjustments tailored to the equipment and applications at the usage site. 【Features】 ■ High dispersibility: Resistant to settling over time ■ Low viscosity: Maintains low viscosity even at a high concentration of 50% w/w ■ Flexible concentration adjustment: Provided in powder form, allowing for concentration adjustments based on equipment and applications ■ Safe and easy management: No need to handle hazardous materials or toxic substances *For more details, please download the PDF or feel free to contact us.

We would like to introduce "fine particle calcium hydroxide" that we handle. It is a food additive equivalent calcium hydroxide, which has antibacterial effects due to its alkalinity and gas adsorption effects for hydrogen sulfide, hydrochloric acid, and other gases. As a result of evaluating a product with 10% added to LDPE sheets, we confirmed an antibacterial effect with a reduction rate of over 99.9% against E. coli. It is also available as a masterbatch. 【Features】 ■ Antibacterial effect due to alkalinity (slightly soluble in water: pH 12.4) ■ Substance used as a food additive ■ Gas adsorption effects for hydrogen sulfide, hydrochloric acid, and others *For more details, please download the PDF or feel free to contact us.

• Other additives

We would like to introduce "Calcium Oxide and Calcium Hydroxide for Food Additives" that we handle. Thanks to our limestone calcination technology, we produce high-purity, high-quality calcium products for food additives. They are characterized by good dispersibility in water and low heavy metal content. We offer three grades of calcium hydroxide for food additives: Hanakouhai, Kuntaro, and Shinsetsu. In particular, Hanakouhai is a product managed under quality standards that are even higher than those for food additives. [Features] - High purity - Good dispersibility in water - Low heavy metal content *For more details, please download the PDF or feel free to contact us.
