Health and hygiene for the public are crucial components of the disinfectant system. Harmful microorganisms on water, surfaces, or in the air can cause infections, lead to food poisoning or contribute to the spread of illness.

It is important to use a disinfectant in your business or home. PHMB or polyhexamethylene biguanide is a potent disinfectant that is frequently employed in clinics, hospitals as well as other healthcare facilities.

Polyhexamethylene biguanide has been proven to be efficient against a variety of microorganisms, such as viruses, bacteria, and fungi. To maximize the effectiveness of PHMB you must be familiar with its properties, features, application, and limitations.

We'll explain everything you need to be aware of about PHMB disinfectant to ensure that you can keep your environment neat and secure.

What is PHMB made of?

A synthetic polymer is polyhexamethylene biguanide. This compound is made up of hexamethylene hydrocarbon chains which connect the fundamental biguanidine units. It is catalytic as well as an amphipathic form.

Due to its structure PHMB is able to display several useful characteristics, such as biocidal action, antifouling characteristics and the capacity of acting as an effective surfactant. PHMB is typically used in concentrations between 0.05-0.5%.

What is PHMB look like?

If you take a look at PHMB, you will observe that it is a colorless liquid. Sometimes, it might be slightly yellow. The exact color will depend on the manufacturing process used and the grade of PHMB that you're making use of.

What is PHMB is used for?

The Polyhexamethylene biguanide hydrochloride is a wide range of applications. In the medical field, it's commonly used in wound care dressings and cleaning products for the perioperative period.

It is also utilized as an antibacterial in contact lens cleaning products and in swimming pool cleaners. PHMB biocide has been proven effective in killing a variety of bacteria, including Gram positive and Gram negative bacteria.

How Does PHMB Work?

The mechanism of action of PHMB makes it an ideal disinfectant. You may be asking yourself how PHMB disinfects surfaces and objects. The process is based on the cationic nature of this chemical.

PHMB may attack the cell membrane when it comes into contact with a microorganism. The following are some ways that PHMB affects microorganisms.

1. Metabolism and Microbial Cell Membranes Disrupted

PHMB is a microbial disruptor that affects cell membranes and metabolic processes. PHMB can interact with cell membranes at low levels and cause them to become more porous.

The greater permeability of cells allows electrolytes and essential nutrients to escape, eventually which leads to cell death. When PHMB is present in higher amounts, PHMB inhibits enzymes involved in cell metabolism, stopping cells from producing the energy required for its function.

Cells lose the ability to perform essential functions, and eventually die. PHMB is a potent disinfectant because it targets multiple cell death mechanisms , making it extremely difficult to resist.

2. Inactivation of Viruses

Many viruses are susceptible to PHMB which includes both enveloped and non-enveloped virus. Enveloped viruses are protected by a membrane of lipids, which PHMB alters the virus, causing it to break down and become ineffective to spread infection through cells.

Although non-enveloped viruses do not have a lipid-based shell, they are vulnerable to PHMB. This substance binds with the capsid of the virus (or the protein shell) and stops the virus from accessing host cells.

PHMB is an extremely effective virucidal agent that can be used to protect against infection.

3. Inhibition of fungal growth

PHMB is also antifungal. This makes it an effective disinfectant for fungi. This chemical blocks the creation of ergosterol which is a key element of fungal cell membranes.

The cell membrane is damaged and unable perform properly without the hormone ergosterol. The result is cell death. PHMB is a powerful way to stop the development of fungi, and keeps your surfaces clean.

4. Prevention of Bacterial Biofilms

Biofilms are bacteria communities which are protected by an extracellular matrix. This matrix protects bacteria from the harsh environment and increases their resistance to disinfectants and antibiotics.

PHMB could disrupt the formation of biofilms by binding to bacteria and blocking them from attaching to surfaces. This makes it more difficult for bacteria to form biofilms, and enhances the effectiveness of disinfection.

What are the unique characteristics of the PHMB

PHMB has many unique attributes that make it a safe and efficient disinfectant. PHMB is suitable for use in:

1. Low Toxic: PHMB is a low-toxic substance that poses no risk to human health. It is an excellent disinfectant to use in the homes and hospitals in addition to other locations where people are present.

2. Environment-friendly: With its low toxicity, PHMB poses minimal risk to the environment. It is safe to use outdoors since it isn't harmful to animals or plants.

3. Non-Flammable: As a non-flammable substance, PHMB is safe to utilize around sources of heat. This makes it perfect for use in kitchens and other areas where open flames are present.

4. Non-explosive: PHMB isn't a flammable substance and isn't a risk to safety. It is therefore safe to use in public spaces and other areas where there are people.

5. Non-corrosive: There's no reason to be concerned about PHMB cause surface corrosion. Due to this property, it can be used as disinfectant in hospitals as well as other places where metal surfaces are present.

6. Non-Irritant to Animal and Human skin: PHMB is non-irritating to human or animal skin, and therefore is safe to use without fear of causing irritation.

7. Odor-Free: Because PHMB is not odorless, it will not produce any unpleasant smells when used in the process of disinfecting. This is crucial for people who are sensitive to strong smells.

How can I utilize PHMB?

To maximize the benefits of PHMB to get the most benefit from it, you need to know how to use it properly. In general, PHMB can be used in conjunction with water. The exact ratio will be contingent on the type of equipment you're using and the type of surface you are disinfecting.

For disinfectants with separate components, it is recommended to use between 100 and 500 mg of PHMB per liter of water. After mixing, spray it on the surface you want to disinfect and let it sit for 10 minutes prior to wiping off with an unclean cloth.

Safety precautions that should be Utilized when using The PHMB

PHMB is an effective and safe disinfectant when it is used correctly. Some safety precautions should be taken when making use of this chemical.

Avoid contact with your eyes: PHMB can cause irritation if it comes in contact with your eyes. Goggles or glasses with protection are recommended to reduce irritation.

Keep it out of the children's reach: PHMB must be kept out of the reach of children to avoid accidental exposure or accidental consumption. It should only be used by adults who understand how to use it safely.

Avoid contact with skin with broken pieces. PHMB should never be applied to damaged or irritated areas. The substance may cause irritation, and therefore it is not recommended to use on skin damaged.

Avoid inhaling: PHMB should not be inhaled. Inhaling this substance accidentally can cause serious health problems.

Conclusion

We are hoping that you have a better understanding about how PHMB disinfectant functions. We've discovered that PHMB is a strong and safe bactericidal, with several distinctive features.

Be sure to mix it with water prior to using it. You must know the PHMB/water ratios for different equipment and surfaces. This will allow you to get the most benefit from this material.

If you are using this substance, you must always exercise caution even though it's relatively safe.

Beware of allowing this substance to touch your eyes or skin. Additionally, you should avoid breathing the fumes. These safety precautions will ensure that you are able to utilize PHMB safely.
