Notice of Participation in Care TEX 2019

A disinfectant cleaner that can rapidly inactivate over 99.999% of the novel coronavirus, non-enveloped viruses, and pathogens. *Samples are currently available!

"Soujisuki PRO" is a low environmental impact disinfecting cleaner made from five minerals (with food additives as the main component). It combines the capabilities of a disinfectant and a cleaner, allowing it to disinfect 99.999% to 99.9999% of the new coronavirus and bacteria while cleaning, even in the presence of dirt. Since it does not contain alcohol, it can be used for virus protection on materials sensitive to alcohol, such as acrylic partitions and face shields. Additionally, because it does not contain chlorine, it prevents metal from rusting and has no irritating odor. It also has strong cleaning power, making it effective for a wide range of applications, including kitchen grease and air conditioning cleaning. 【Features】 - Inactivates and cleans envelope and non-envelope viruses - Does not rust metal due to the absence of chlorine, and has no irritating odor - Can be used for virus protection on acrylic partitions and face shields due to the absence of alcohol - Strong cleaning power, effective against grease and protein stains - Forms a silica (SiO2) film (hydrophilic) after cleaning, providing anti-fouling effects - Can be used on aluminum materials Ingredients: Carbonate (food additive), phosphate (food additive), silicate (mineral) Liquid properties: Alkaline, odorless, chlorine-free

Inactivation of the new coronavirus! An odorless disinfectant made only from food additive ingredients! *Samples are being distributed.

"Jokinski" is an alkaline disinfectant made solely from food additive components that do not contain harmful alcohols or chlorine-based ingredients, which are a concern for health and odor. In addition to its immediate inactivation and disinfection efficacy within 15 seconds, it maintains a stable high alkalinity, enabling a synergistic effect that suppresses the growth of harmful bacteria through the breakdown of edible oils and proteins while simultaneously disinfecting and inactivating. Furthermore, it contains no alcohol or sodium hypochlorite and is odorless, leaving no unpleasant smell behind. Because it does not use alcohol, it can be used for virus prevention in materials sensitive to alcohol, such as acrylic partitions and face guards. [Features] - Unlike alcohol-based disinfectants, there is no decrease in disinfecting power due to evaporation or concentration reduction. - Alcohol-free, making it suitable for use in virus prevention for acrylic partitions and face guards. - "Jokinski" achieves stable rapid inactivation (over 99.999% in 15 seconds) against enveloped and non-enveloped viruses. - Colorless, transparent, and odorless. Ingredients: Phosphate (food additive), grapefruit seed extract (food additive) Liquid properties: Alkaline, colorless, odorless, alcohol-free.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
