Wet wipes have become an essential product in daily life, healthcare, personal care, baby care, household cleaning, and industrial applications. Because wet wipes contain a high percentage of water and nutrients that can support microbial growth, effective preservation is one of the most important challenges for wet wipe manufacturers.
Unlike dry products, wet wipes are continuously exposed to microbial contamination risks during production, filling, transportation, storage, and consumer use. Without an effective antimicrobial preservative system, wet wipes may develop unpleasant odors, discoloration, microbial contamination, and reduced product performance.
Among various antimicrobial ingredients, PHMB (Polyhexamethylene Biguanide Hydrochloride) has attracted increasing attention as a high-performance preservative for wet wipes due to its broad-spectrum antimicrobial activity, excellent water solubility, and long-lasting microbial control capability.
Today, PHMB preservative is widely evaluated and used in antibacterial wet wipes, household wipes, medical wipes, personal care wipes, and other water-based antimicrobial products.
For wet wipe manufacturers looking for a reliable antimicrobial solution, PHMB offers a balance between preservation performance, formulation flexibility, and cost efficiency.
PHMB is the abbreviation of Polyhexamethylene Biguanide Hydrochloride, also known as:
PHMB belongs to the biguanide polymer family and is a cationic antimicrobial polymer. It works mainly by interacting with negatively charged microbial cell membranes, causing membrane disruption and preventing microbial reproduction.
The typical information of PHMB includes:
Chemical Name: Polyhexamethylene Biguanide Hydrochloride
INCI Name: Polyaminopropyl Biguanide (depending on regulatory market)
CAS Numbers:
PHMB is available in different forms, including aqueous solutions and powder forms. For wet wipes applications, PHMB solution is usually preferred because it provides easier dispersion and better formulation control.
The biggest advantage of PHMB preservative for wet wipes is its broad antimicrobial activity.
Wet wipes can be contaminated by different microorganisms, including:
PHMB helps control microbial growth and maintain product stability during the entire shelf life.
For antibacterial wet wipes, PHMB can provide additional antimicrobial functionality beyond traditional preservation.
Compared with conventional preservatives that mainly prevent microbial growth inside the formulation, PHMB provides both:
This makes PHMB especially attractive for:
Wet wipes formulations are mainly water-based systems.
A suitable preservative for wet wipes must have:
PHMB has excellent water compatibility, allowing formulators to easily incorporate PHMB into aqueous wipe solutions.
Typical wet wipe formulations may include:
PHMB can be added into the liquid phase during manufacturing to provide uniform antimicrobial protection.
One major challenge for wet wipe manufacturers is maintaining microbial control throughout the product lifecycle.
A package of wet wipes may be opened repeatedly by consumers, allowing microorganisms from hands, air, and environment to enter the package.
PHMB preservative helps maintain microbial protection after repeated exposure.
This is especially important for:
Baby wipes require extremely careful preservative selection because they are used on sensitive skin.
Important requirements include:
PHMB is considered by some formulators as an antimicrobial ingredient for specialized wipe products.
However, manufacturers must carefully evaluate regulatory requirements and safety assessments for each market.
Personal care wipes include:
These products usually require preservation systems that can maintain product safety while providing consumer-friendly formulations.
PHMB preservative can be considered as part of an antimicrobial preservation strategy.
Household wipes are one of the important application areas for PHMB.
Examples include:
For household applications, strong microbial control is usually a priority.
PHMB has been used in various antimicrobial wipe products and disinfectant applications.
Wet wipe manufacturers commonly use preservatives such as:
However, different preservatives have different advantages.
| Preservative | Main Advantage | Limitation |
|---|---|---|
| Phenoxyethanol | Widely accepted, mild | Limited antimicrobial spectrum |
| Sodium Benzoate | Natural positioning | Requires suitable pH |
| MIT/CMIT | Strong antimicrobial activity | Regulatory restrictions |
| Benzalkonium Chloride | Excellent antibacterial effect | Cationic compatibility issues |
| PHMB | Broad antimicrobial performance | Requires formulation evaluation |
PHMB is particularly suitable when manufacturers need stronger antimicrobial protection rather than simple preservation.

This long-term cooperation demonstrates the growing demand for PHMB preservative in the global wet wipes market.
Developing a successful wet wipe formulation requires more than simply adding an antimicrobial ingredient. Wet wipe manufacturers need to consider the interaction between PHMB, fibers, surfactants, moisturizers, preservatives, and other functional ingredients.
A properly designed PHMB preservative system should achieve:
The actual PHMB dosage depends on the product category, target microorganisms, regulatory requirements, and preservative challenge test results.
The dosage of PHMB preservative in wet wipes varies depending on the application.
Typical considerations include:
Personal care wipes usually focus on mildness and consumer safety.
Applications:
The PHMB level is generally optimized at a low concentration to achieve preservation while maintaining skin compatibility.
For antibacterial wet wipes, PHMB is often selected because of its antimicrobial performance.
These products require stronger microbial control against:
The final concentration should be determined through:
Household wipes normally require stronger antimicrobial protection because they are designed for:
PHMB can be incorporated into household wipe formulations as part of an antimicrobial solution.
A key advantage of PHMB preservative is its compatibility with many water-based formulations.
However, formulators should evaluate interactions carefully.
Wet wipes often contain surfactants for cleaning performance.
Examples:
Because PHMB is a cationic polymer, strong anionic surfactants may reduce its effectiveness.
Therefore, formulation testing is recommended before commercial production.
Chelating agents are often used in wet wipes to improve preservation performance.
Common chelators include:
Chelating agents can help improve microbial control by binding metal ions required for microbial growth.
A combination of PHMB and suitable chelating agents may provide enhanced preservation performance.
