PHMB for sterilization and antibacterial spray.

For anti-virus measures! A disinfectant spray containing a third disinfectant [PHMB]

In homes with small children and the elderly, many people may be wondering what disinfectant spray to use for anti-virus measures. Due to the worldwide spread of the new coronavirus, gargle/hand washing, diligent ventilation, and regular sterilization of areas where fingers touch are recommended at home.

However, it is said that the more effective the disinfectant spray used to disinfect bacteria and viruses, the more virulent it becomes. It can also result in illness. Therefore, this time, we would like to introduce [KINTOL ™ sterilization/antibacterial spray] containing PHMB (sterilization / antibacterial ingredient) that many people can use with peace of mind.

Antibacterial and Sterilization ingredients effective for disinfecting viruses and bacteria

There are several disinfection and sterilization methods that are effective against viruses and bacteria, but in general, when disinfecting the skin of hands, etc., the surface of pharmaceuticals / quasi-drug alcohol, handrails, doorknobs, etc. Chlorine bleach (sodium hypochlorite) is effective against bacteria.

Each disinfectant/disinfectant has its own characteristics, so choose the one that suits your purpose.

Characteristics of alcohol-based disinfectants

  • By rubbing alcohol (ethanol) with a concentration of 70% or more in your hand, it breaks the virus membrane and detoxifies it. * Not all bacteria and viruses have the same effect.

  • A pungent odor is generated on the nose

  • The skin oil film dries and causes rough skin and rough hands.

  • Causes surface deterioration of leather products, rubber, wood products, and resins

Characteristics of chlorine bleach (sodium hypochlorite)

  • The virus is detoxified by diluting the sodium hypochlorite concentration to 0.05% and wiping it with water. * Not all bacteria and viruses have the same effect.

  • Like alcohol, it has a strong pungent odor.

  • Can cause severe sores when attached to the skin

  • Since it is corrosive to metals, it cannot be used for metals.

  • Since it has a high bleaching effect, it may cause decolorization when used on textiles and wood.

What is the next-generation sterilization component [PHMB]?

[PHMB (polyhexamethylene biguanide)] is attracting attention as a safer disinfectant than alcohol-based disinfectants and sodium hypochlorite. PHMB has been used as an industrial disinfectant for more than 30 months in the world and is said to have little effect on the human body so that it can be introduced in facilities and medical sites used by babies and the elderly. Examples of domestic use include contact lens preservatives, wet wipes, and leisure facilities. It seems that it is sometimes used in food processing factories and brewing factories.

Next, I would like to tell you about the many merits of PHMB.

Advantages of PHMB (1): Demonstrates extremely high sterilization, virus eradication, and antibacterial effects.

  • PHMB can sterilize viruses where your fingers touches, such as doorknobs, railings, and washroom faucets. Independent tests have shown a significant inactivating effect of over 99.9%. * Name of the testing institute: Food Environment and Sanitation Research Institute Co., Ltd. * Not all bacteria and viruses have the same effect.

Advantage of PHMB (2): Can be used in places with a lot of organic substances such as sebum

  • PHMB is said to be less effective in half even if it has protein stains such as sweat, oil, and sebum. In general, places with a lot of organic matter (sweat, sebum, etc.) tend to be less affected by sterilization, but PHMB is also characterized by the fact that the sterilization effect does not easily decrease even in places with organic matter. Therefore, it is also suitable for disinfecting hospitals, bathing facilities, fitness gyms, etc. where protein tends to remain.

Advantage of PHMB ③: No odor peculiar to chemicals used for sterilization

  • Since PHMB is odorless, the odor of the drug does not occur even after sterilization. It is also recommended for places where you can enjoy eating and drinking such as restaurants and taverns, and for relaxing spaces where you usually use air fresheners such as aromas.

Advantage of PHMB ④: Non-irritating, so it is safe for people with sensitive skin

  • Since PHMB is non-irritating, it has almost no effect even if it adheres to the skin. *The increasing number of cases of disinfectants containing PHMB as an ingredient in hospitals is largely due to non-irritation. It is also suitable for use in places where a large number of unspecified people come and go, such as public transportation and large commercial facilities. * [KINTOL ™ sterilization / antibacterial spray] is classified as a "safe product" after undergoing a skin irritation test at a concentration of 500 ppm.

Advantage of PHMB ⑤: Does not damage all equipment (metal, rubber, wood)

  • Some disinfectants used for anti-virus measures may contain ingredients that damage or decolorize equipment or facilities. Since PHMB hardly damages metal, rubber, and wood, it is possible to sterilize a wide range of objects such as machinery, kitchen utensils, home appliances, packing, and furniture using wood. Since it is possible to disinfect every part with a single disinfectant spray containing PHMB, it is also recommended for those who are looking for commercial disinfection such as restaurants and facilities.

Advantage of PHMB ⑥: The sterilization effect can be maintained even in water.

  • Alcohol-based disinfectants are volatile, so it is difficult to disinfect places that are wet with water. However, PHMB is a non-volatile component, so it does not matter even in water. It can also be effective with hot water instead of water. It is also used in swimming pools and attractions that use water.

PHMB-based [KINTOL ™ sterilization / antibacterial spray]

[KINTOL ™ sterilization/antibacterial spray] was developed as a "third-generation" disinfectant spray containing PHMB. As a secondary material, algae-derived ingredient Kokkomixa is also included.

The PHMB raw materials used in [KINTOL ™ sterilization/antibacterial spray] are domestic raw materials and manufactured in Japan.

Until now, disinfectant sprays have been divided into alcohol (ethanol) and chlorine-based products, but [KINTOL ™ sterilization/antibacterial spray] does not contain any alcohol / chlorine-based components and is a new genre. It is classified as a 3rd generation disinfectant spray because it is a disinfectant spray.

[KINTOL ™ sterilization/antibacterial spray] has acquired antibacterial sustained data for more than one week at the Tokyo Food Technology Research Institute of the Tokyo Food Sanitation Association, and maintains the antibacterial effect for a long time even after use. It is a disinfectant spray that can be used.

Obtained numerous evidence considering safety

In order to use our products with greater peace of mind, we obtain various types of evidence in-house at a third-party research institute. We have conducted strict tests such as virus inactivation effect test, skin irritation test, oral acute toxicity test, oral mucosa irritation test, and sterilization test against Escherichia coli and Staphylococcus aureus. We carry out safety tests and effectiveness tests in consideration of users.


If you go to drug stores or pharmacies, you will find many disinfectant sprays lined up. You may not know which one to choose because there are too many. As a criterion for choosing a disinfectant spray, we recommend that you consider not only the effect but also the safety aspect.

No matter how effective the disinfectant spray is against viruses, it is meaningless if the disinfectant spray itself has an adverse effect on the human body.

[KINTOL ™ sterilization/antibacterial spray] is an item that can meet both needs.

Please consider a new lifestyle in the future.
