Preservation Challenges in Wipes Liquid Systems

Wipes liquid is the core component of wet wipes products. As a high-water-content formulation, wipes liquid is highly vulnerable to microbial contamination during production, storage, and consumer use.

For wet wipes manufacturers and OEM factories, selecting a reliable preservative system for **wipes liquid formulation** is critical to ensure product safety, shelf life, and global regulatory compliance.

**PE 9010** is one of the most commonly used preservative systems in wipes liquid for personal care and hygiene wet wipes. This article provides a comprehensive overview of **PE 9010 in wipes liquid applications**, including benefits, usage levels, formulation guidelines, and manufacturing considerations.

What Is PE 9010 Preservative?

PE 9010 is a broad-spectrum preservative blend composed of:

**Phenoxyethanol**

**Ethylhexylglycerin**

This combination is widely used in **wipes liquid formulation** due to its synergistic antimicrobial effect and good skin compatibility, making it suitable for leave-on wet wipes products.

Key Features of PE 9010 for Wipes Liquid

* Broad-spectrum antimicrobial protection

* Paraben-free and formaldehyde-free

* Effective in a wide pH range (3.0–10.0)

* Low odor, suitable for fragrance-free wipes liquid

* Compatible with most wipes liquid ingredients

Why PE 9010 Is Widely Used in Wipes Liquid

1. Effective Preservation in High-Water Wipes Liquid

Wipes liquid contains a high percentage of purified water, which creates ideal conditions for microbial growth. PE 9010 provides reliable antimicrobial protection against bacteria, yeast, and mold in wipes liquid systems.

Phenoxyethanol delivers strong antibacterial efficacy, while Ethylhexylglycerin enhances overall preservation by disrupting microbial cell membranes.

2. Mildness for Skin-Contact Wipes Liquid

Since wipes liquid is in direct contact with skin, especially in baby wipes and facial wipes, mildness is essential. PE 9010 is well recognized for its good skin tolerance, making it suitable for:

* Baby wipes liquid

* Facial cleansing wipes liquid

* Feminine hygiene wipes liquid

* Sensitive skin wipes liquid

3. Global Market Compliance for Wipes Liquid Products

PE 9010 is accepted under major cosmetic regulations worldwide, which makes it ideal for **export-oriented wipes liquid formulations** supplied to Europe, the United States, the Middle East, and Asia.

Recommended Dosage of PE 9010 in Wipes Liquid Formulation

Typical usage level of PE 9010 in wipes liquid:

* **0.5%–1.0%** (w/w) of the total wipes liquid formulation

The optimal dosage depends on:

* Water quality used in wipes liquid

* Microbial load of raw materials

* Packaging type and opening frequency

* Target shelf life of the wet wipes product

Preservative efficacy testing is recommended for all wipes liquid formulations.

How to Formulate Wipes Liquid With PE 9010

Addition Method in Wipes Liquid Production

PE 9010 is typically added during the **cool-down stage** of wipes liquid manufacturing, after all water-soluble ingredients are fully dissolved. It disperses easily in wipes liquid systems.

pH Adjustment for Wipes Liquid

Although PE 9010 is effective across a wide pH range, wipes liquid is commonly adjusted to **pH 5.0–7.0** for skin comfort and optimal preservative performance.

Compatibility With Common Wipes Liquid Ingredients

PE 9010 is compatible with:

* Humectants (glycerin, propanediol)

* Mild surfactants used in wipes liquid

* Botanical extracts and soothing agents

* Chelating agents (EDTA, sodium phytate)

For enhanced preservation of wipes liquid, chelating agents or multifunctional boosters are often recommended.

Application of PE 9010 in Different Wipes Liquid Types

Baby Wipes Liquid

PE 9010 provides gentle yet reliable preservation for baby wipes liquid, meeting safety and mildness requirements.

Facial & Makeup Removal Wipes Liquid

Its low odor and good compatibility make it suitable for wipes liquid containing surfactants and emollients.

Feminine Hygiene Wipes Liquid

PE 9010 performs well in wipes liquid formulated with mild pH and sensitive-skin positioning.

Household & General Cleaning Wipes Liquid

In non-alcohol or low-alcohol systems, PE 9010 can be used as part of a complete wipes liquid preservation strategy.

Common Preservation Issues in Wipes Liquid Manufacturing

Wet wipes manufacturers often encounter challenges such as:

Secondary contamination of wipes liquid during repeated use

* Microbial growth in nonwoven substrates soaked with wipes liquid

* Reduced preservative efficacy due to poor water quality

A stable wipes liquid formulation requires not only PE 9010, but also good GMP practices and proper water treatment.

Microbial Challenge Testing for Wipes Liquid With PE 9010

Even with a proven preservative system, **challenge testing of wipes liquid** is essential.

Key influencing factors include:

* Type of nonwoven fabric

* Liquid-to-wipe ratio

* Packaging structure (flow pack, tub)

* Storage and transportation conditions

Test results help optimize PE 9010 dosage and overall wipes liquid formulation design.
