Because the trend is the premise to create the trend, but the right direction brings sustainable value.

2020 is the year of the global outbreak of respiratory disease, leading to hotter topics related to personal health protection and community infection prevention. The Covid-19 epidemic as a warning bell makes the majority of us suddenly wake up, pay more attention, and focus more on "Living healthy, living clean and living safely". Along with the increase in consumer demand, the market for germicidal products has also become extremely active with the appearance of many product lines such as hand sanitizer, alcohol sanitizer... That's the market, always follow the short-term needs of "God" but sometimes "forget" the long-term values, which are Quality and Safety.

The idea of KENTORI products was born in the context of the market becoming overloaded with antibacterial products. With the slogan "NOT ONLY CLEANING, BUT SAFETY", KENTORI products were born with the desire to bring Vietnamese consumers germicidal products with the most stable quality and activity.

Our success is not only in creating the brand but also in the fact that we always set the highest standards for each product. KENTORI-product line applying active ingredient HOCL, capable of killing many types of bacteria, viruses, pathogenic fungi, and ABSOLUTELY SAFE for health, does not cause irritation, allergies on even the skin fragility of infants.

KENTORI is the product of the most advanced Japanese technology, surpassing even the product of electrolysis technology. Besides, we are always interested in environmental protection, which is also our strength compared to the vast majority of products on the market today. Our bactericidal active ingredients will completely decompose after bactericidal, without fear of chemical residues and affecting the ecological environment.

KETORI is confident to bring consumers the best quality products.

To maintain personal hygiene and reduce the risk of disease, advice from epidemiologists is to wash your hands often. Hand washing will help eliminate harmful microorganisms, thereby limiting the ability of those microorganisms to enter the human body. However, improper hand washing and the selection of chemical and alcohol-based hand sanitizers will harm the skin of the hands and the risk of chemical residues is very high. So, how should we clean and care for our hands? Let's find out with us.

  • Wash your hands according to the instructions of the Ministry of Health to eliminate bacteria and viruses that cause disease according to the specific procedures as follows:

  • Use protective gloves: Using gloves will limit direct skin contact with objects with a high risk of infection or harmful chemicals. It is also important to choose good quality, soft and comfortable gloves and to change them regularly. However, gloves are not always available, especially in public places, so it is essential to proactively prepare an effective and safe germicidal product.
  • Choose the right hand sanitizer that is effective and safe: usually, washing hands with soap and water is the most effective at removing dirt. However, it is not always possible. Therefore, using quick hand sanitizer will bring many conveniences. However, you should choose a fast hand sanitizer product with clear origin, effective bactericidal ability, benign ingredients, and little or no fragrance that is harmful to the skin of your hands.
  • Provide necessary moisture to care for hand skin: Besides choosing a reasonable hand sanitizer, supplementing skin with nutrients is also really necessary. Depending on your preferences and the nature of your skin, you can choose a suitable hand care product.

The market today is very diverse with antibacterial products or dry hand sanitizers that have the ability to kill bacteria and viruses. However, many of them are unclear in origin and composition, even containing chemical ingredients that are harmful to the skin.

Dr. Bui Quang Hao, Head of Infection Control Department (Central Hospital of Dermatology) said that recently, the hospital has received many cases of allergic contact dermatitis, redness, peeling, itching... Using medical history, many patients said that in the past few days, they have used disinfectant solutions bought floating on the market or used homemade solutions to disinfect hands to prevent Covid-19. It is not possible to confirm whether 100% is caused by the use of rapid hand sanitizer by the patient because clinical or specific testing is required, but the use of floating products, of unknown origin, has not been confirmed. tested by authorities can affect the skin of the hands and increase the risk of disease.

With alcohol-based hand sanitizers, if the alcohol concentration is too low (below 60 degrees), there is no bactericidal effect or poor bactericidal effect. Meanwhile, if the alcohol concentration is too high (90 degrees), it will coagulate and clot the protein layer on the surface of bacteria and viruses, reducing the bactericidal effect. Although alcohol-based disinfectants have a bactericidal effect, long-term use will cause dryness and peeling of the skin of the hands.

In addition, the doctor also said that quick antiseptic products that do not need to be rinsed with water often contain a large amount of chemicals, so it leaves a large chemical residue on the skin causing an unpleasant odor. Quick hand sanitizer also often contains BPA, a very dangerous chemical that affects the endocrine system leading to cancer, this chemical can enter the body if hands accidentally come into contact with the eye area or mouth…

Thereby, it can be concluded that choosing a standard germicidal product with clear origin is extremely necessary in maintaining hygiene and protecting health. Doctors recommend that consumers buy antibacterial products at reputable stores, besides that consumers should also learn about ingredients, active ingredients, and concentrations before making a choice. For young children, it is recommended to use specialized bactericidal products, and when children use it, it is necessary to have parental supervision.

The use and abuse of chemicals in disinfection causes many serious consequences. Let's take a look at some of the most dangerous disinfectants:

Chloramine B antiseptic:

Besides a very good and effective disinfectant effect, chloramin B can be toxic to people who are in direct contact with chemicals such as: Skin damage, skin burning and discomfort; Eye damage to the cornea, even blindness; Respiratory damage causes smooth muscle spasms, difficulty breathing…

When using Chloramin B chemicals, absolutely must follow the instructions for use of the Ministry of Health, need to handle immediately when there are signs of poisoning caused by chloramin B, specifically:

When sucking or swallowing chloramin B antiseptic tablets or powder, the patient should immediately drink a warm, unstimulated amount of water to try to induce vomiting and must immediately go to the nearest medical facility for intervention. .

When breathing air containing the concentrated active chlorine chemical of chloramin B, the victim must be removed from the contaminated air area immediately and quickly transferred to the nearest medical facility for treatment.

When chemical splashes into the eyes, wash eyes and face immediately with clean water several times, and also immediately go to the nearest medical facility for examination. When chemicals are splashed on clothes or on skin, immediately remove contaminated clothing, wash the skin area with warm clean water and soap.

Methanol (Industrial Alcohol):

Alcohol is a disinfectant that is widely used because it is cheap, easy to buy, highly active, but just careless, in the disinfectant solution, use the wrong alcohol, use industrial alcohol, not medical alcohol (Ethanol). it would be very dangerous.

Industrial alcohol – specifically Methanol, a toxic alcohol used industrially as a solvent and insecticide. Inhalation of high concentrations of methanol vapor and absorption of methanol through the skin are just as effective as oral administration in producing toxic effects. The fatal dose of pure Methanol is estimated at 1 to 2 ml/kg. However, there have been cases of permanent blindness and death with doses of only 0.1ml/kg. Initial adverse effects from methanol poisoning include drowsiness, decreased consciousness (central nervous system depression), confusion, headache, dizziness, and inability to coordinate muscle movements (ataxia). draw). More serious can cause acid buildup in the blood (metabolic acidosis), blindness and death.

When there are symptoms of industrial alcohol poisoning, it is necessary to immediately bring the patient to the nearest medical facility for timely rescue and treatment.

The principle of timely response to the patient is to ensure stable physiological indicators for the patient.

Using specific antidote measures, early dialysis may be indicated if there is clear evidence. Test the concentration of Methanol and Ethanol in the patient's body to give a reasonable treatment direction.

Treatment of symptoms and complications, supportive treatment in the recovery phase.

Ozone disinfectant: 

Ozone has many applications in life thanks to its excellent disinfecting and bactericidal properties. However, when using ozone, it is necessary to be very careful and pay attention to the concentration, usage and dosage because ozone is harmful to human health, especially for the elderly, children and people with diseases. Respiratory. According to the recommendations of the National Institute of Occupational Safety and Health, the concentration of ozone in the air should not exceed 0.10 ppm at any time. There is no recommendation to use ozone to disinfect clothes and human skin under normal conditions. Ozone gas easily causes respiratory diseases such as bronchitis, rhinitis ... mainly in the nervous system and respiratory tract.

Ozone poisoning usually begins with headache, shortness of breath, and dry cough. In more severe cases, asthma or vision damage, lens damage leading to blindness. The World Health Organization (WHO) has set the safe threshold for ozone as 0.06 ppm (0.06ml ozone/1 liter of air). So when you start to smell the fishy smell of ozone (when the ozone concentration is about 0.02-0.05 ppm), you should stay away immediately, especially for people with asthma or children. In addition, ozone gas can also damage rubber materials and quickly rust metal objects in the house. Therefore, do not stay in the room while using ozone to deodorize and kill bacteria. In particular, when smelling the burning smell of ozone, we should stop and open the window for ventilation. When there are symptoms of poisoning, it is necessary to immediately go to the nearest medical facility for assistance.


Hypochlorous acid solution (HOCL) produced by Japanese technology is currently a new option besides Chloramin B solution for disinfection.

With outstanding advantages in safety such as non-irritating to the skin including sensitive areas such as the face and mouth, non-toxic when in contact with organic substances, quickly decomposing into water and evaporating after spray,

HOCL is recommended by the FAD as an alternative to alcohol-based disinfectants and other harmful chemicals.
