What is hypochlorous acid water?Solutions that can be used for disinfection according to different concentration characteristics

Hypochlorous acid water, the main component of which is hypochlorous acid (HClO), is a weak acid solution. Its chemical structure is similar to that of bleach water (sodium hypochlorite NaClO), but it is a different chemical. Regarding the differences between the two, There will be more detail in the next paragraph.Hypochlorous acid water has the property of destroying the cell membrane of bacterial pathogens, so it has a certain disinfection effect.If it is used for environmental disinfection, the recommended concentration is 100-300ppm, and some people will use it for disinfection of tableware, vegetables and fruits, and the recommended concentration is 20-90ppm, but it must be noted that not every ingredient can be used Hypochlorous acid water disinfection, and it is best to confirm the concentration and scope of application of the product before use.

What is the difference between hypochlorous acid water and sodium hypochlorite (bleach)?

Although the molecular structures of hypochlorous acid water and sodium hypochlorite are similar, there are still differences, especially in the bactericidal effect and scope of application.In addition, the factors that affect the sterilization effect of the two are also different. The following table summarizes the differences for you:


Hypochlorous acid water

Sodium hypochlorite (bleach)

Main components

Hypochlorous acid (HClO)

Sodium hypochlorite(NaClO)

recommended concentration

Food and tableware cleaning: 20-90ppm

Environmental disinfection wipe: 100~300ppm

Not for cleaning food and utensils

Environmental disinfection wipe: about 500ppm

Sterilization principle

Destroys bacterial or viral cell membranes or mantles through strong oxidation

spoil the pathogen's proteins

Scope of use

Do not touch metal, otherwise it will cause rust, and direct contact with the human body is not recommended.

It is necessary to avoid contact with the following materials: contact with nylon, plastic, wool, metal, paint, silk and colored fabrics, etc., and direct contact with the human body.

Storage considerations

It should be stored in an opaque container and used up as soon as possible to avoid reducing the disinfection effect.At the same time, because it is nearly colorless and odorless after dilution, it should be placed in a place out of the reach of children, and there should be clearly identifiable labels outside the storage container to avoid the risk of accidental ingestion.

Undiluted sodium hypochlorite will produce toxic gas when exposed to sunlight. It is a highly irritating liquid to human mucous membranes, skin and respiratory tract, and accidental contact should be avoided.

    How to use hypochlorous acid water to be effective?3 major factors affecting the efficacy of hypochlorous acid water

    Since the sterilization principle of hypochlorous acid water is through oxidation, factors such as storage conditions, dilution concentration, etc. will affect the sterilization effect of hypochlorous acid water. The following will explain the use of hypochlorous acid water.

    Hypochlorous acid water efficacy factor 1: storage conditions

    The chemical properties of hypochlorous acid water are not stable, and it is afraid of light and heat. Even if it is placed in a closed light-blocking container, the sterilization effect will be greatly lost after 3 months, so it is not easy to store in large quantities and for a long time. In the home space, it is best to prepare it when it is used.

    Factor 2 affecting the efficacy of hypochlorous acid water: dilution concentration

    The concentration of hypochlorous acid water will affect the sterilization effect, and the sterilization effect is not good if the concentration is too low.For environmental disinfection, the most suitable solution concentration is about 100-300 ppm, and pH 5.5-6.5 is an ideal solution.

    Factor 3 that affects the efficacy of hypochlorous acid water: how to use it

    Spray directly at the disinfection target at a distance of about 30 cm, and stay for 30 seconds after spraying to ensure enough time to destroy the pathogen. It is the most ideal way to use hypochlorous acid water.

    • Lack of relevant specifications and management details, so it should be used with caution
    • The bactericidal power is unstable due to factors such as use and storage
    • It is more difficult to test that the actual concentration of the product is consistent with the label
    • The disinfection effect is "short time" and "one-time"

    In conclusion, if the concentration, storage conditions, and method of use are all appropriate,Hypochlorous acid water is good for disposable environmental disinfection sprays, but not for humans.
