Euxyl PE 9010 Explained: Phenoxyethanol + Ethylhexylglycerin in Cosmetic Formulation

Euxyl PE 9010 is one of the most commonly searched cosmetic preservatives, especially among makers formulating lotions, cleansers, sprays, and other water-based products.

Many people search for terms like Euxyl PE 9010, phenoxyethanol ethylhexylglycerin preservative, or Euxyl alternative, because they want a preservative that is effective, widely accepted, and relatively easy to use.

Natural Bulk Supplies offers this system as Preservative - Phenoxyethanol + Ethylhexylglycerin, which follows the same industry-recognized preservation logic and performance profile as Euxyl PE 9010.

This guide explains how this preservative system works, what it does well, where its limits are, and how to use it correctly in real cosmetic formulas. It is written to align with professional supplier guidance from companies like Lotioncrafter and Making Cosmetics, while remaining original and easy to understand.

What Is Euxyl PE 9010

Euxyl PE 9010 is a preservative system made from two ingredients: phenoxyethanol and ethylhexylglycerin.

Phenoxyethanol is the primary preservative component. It provides strong antibacterial protection and is widely used in both leave-on and rinse-off cosmetic products.

Ethylhexylglycerin acts as a preservative booster. It enhances the overall effectiveness of the system, especially against yeast and mold, and helps improve the performance of phenoxyethanol.

Together, these ingredients create a preservative system that is flexible and widely accepted in modern cosmetic formulation.

Is This the Same as Other Phenoxyethanol Systems

This is an important point for makers.

Phenoxyethanol + ethylhexylglycerin is not the same as phenoxyethanol + caprylyl glycol, and it is not the same as Optiphen Plus.

Each system behaves differently.

Ethylhexylglycerin and caprylyl glycol are not interchangeable boosters. They differ in solubility, compatibility, and how they interact with other ingredients.

Understanding this difference helps prevent preservation mistakes.

Is Euxyl PE 9010 Broad Spectrum

Euxyl PE 9010 is considered a broad spectrum preservative system when used correctly.

Phenoxyethanol provides strong bacterial control, while ethylhexylglycerin improves resistance to yeast and mold.

In most everyday cosmetic formulations, this system provides reliable protection when formulation risk is reasonable and good manufacturing practices are followed.

High-risk products, such as those with very heavy botanical loads, sugars, or jar packaging used in wet environments, may require additional testing or supportive hurdles.

pH Range and Stability

One advantage of Euxyl PE 9010 is its relatively wide pH tolerance.

This system generally performs well in formulations with a pH range of approximately 3 to 8.5, though many formulators prefer to keep products below pH 8 for long-term stability.

Even with this flexibility, pH testing remains important. Certain ingredients can slowly shift pH over time, especially botanical extracts and proteins.

Solubility and Why It Matters

Unlike fully water-soluble preservatives, Euxyl PE 9010 has limited solubility in water.

If added directly to a water phase without proper dispersion, it can separate or distribute unevenly.

To improve incorporation, many formulators pre-mix this preservative with a compatible solvent such as glycerin, propylene glycol, propanediol 1,3, or sorbitol before adding it to the batch.

Proper solubility and mixing are critical for consistent preservation.

When and How to Add This Preservative

Euxyl PE 9010 is typically added during the cool down phase of formulation.

Adding it at lower temperatures helps protect preservative performance and allows better control over mixing and distribution.

After adding, mix thoroughly to ensure the preservative is evenly dispersed throughout the product.

Typical Use Levels

Euxyl PE 9010 is commonly used within the supplier-recommended range, often around 0.5 to 1 percent depending on the formulation.

Using more than recommended does not improve preservation and may increase the risk of irritation.

Always follow the usage guidance provided for the specific preservative system.

Products That Commonly Use Euxyl PE 9010

This preservative system is widely used in:

• Lotions and creams
• Facial and body cleansers
• Hand soaps and surfactant-based products
• Toners, mists, and sprays
• Emulsified serums

It performs especially well in products where a balance between effectiveness and formulation flexibility is desired.

Surfactant Compatibility Considerations

Euxyl PE 9010 can have limitations with certain surfactant systems.

Some ethoxylated surfactants may reduce preservative effectiveness or cause compatibility issues.

When using this preservative in surfactant-heavy formulas, additional evaluation and testing are recommended.

Packaging Considerations

Packaging plays a role in preservative success.

Pump bottles and airless packaging reduce contamination risk and work very well with this system.

Wide mouth jars increase contamination pressure and should be paired with good manufacturing practices and appropriate testing.

Common Mistakes Makers Make

• Assuming all phenoxyethanol systems behave the same
• Ignoring solubility and dispersion
• Skipping pH testing
• Using the preservative in very high-risk formulas without testing
• Relying on the preservative to compensate for poor hygiene

Is Euxyl PE 9010 Natural or Naturally Compliant

Euxyl PE 9010 is considered a conventional cosmetic preservative system.

It is widely accepted in professional formulation due to its performance, versatility, and safety profile.

Do You Still Need Testing

Yes. Even reliable preservative systems require testing when products are sold.

Stability testing confirms that pH and texture remain consistent over time.

Microbial and challenge testing confirm that the preservative works in your specific formula and packaging.

How This Preservative Fits Into a Preservation Strategy

Euxyl PE 9010 works best as part of a complete preservation approach.

Clean manufacturing practices, proper packaging, correct pH, and thoughtful formulation design all support its performance.

When used correctly, this preservative system provides dependable protection for many cosmetic products.

Final Thoughts

Euxyl PE 9010 remains a popular choice because it offers a balance between effectiveness and ease of use.

For many makers, Preservative - Phenoxyethanol + Ethylhexylglycerin is a practical option for lotions, cleansers, and sprays.
