In modern cosmetic formulations, choosing the right preservative system is critical for product safety, regulatory compliance, and market success. As global cosmetic regulations tighten and consumers demand gentler, high-performance formulas, Phenoxyethanol and Ethylhexylglycerin have become one of the most widely adopted preservative combinations worldwide.
The blend of Phenoxyethanol and Ethylhexylglycerin, commonly known as PE91, is now a benchmark preservative system in skincare, haircare, baby care, and personal care products. This system offers broad-spectrum antimicrobial protection while maintaining excellent skin compatibility and formulation flexibility.
As an experienced Phenoxyethanol and Ethylhexylglycerin manufacturer and supplier, Suzhou Easy Chemical Co., Ltd provides high-purity PE91 to support modern cosmetic preservation strategies for global brands and OEM manufacturers.

Phenoxyethanol and Ethylhexylglycerin is a synergistic cosmetic preservative system composed of two globally approved ingredients:
Phenoxyethanol – a highly effective preservative with strong antibacterial activity, particularly against Gram-negative bacteria.
Ethylhexylglycerin – a multifunctional ingredient that enhances antimicrobial efficacy while acting as a skin-conditioning agent.
When combined, Phenoxyethanol and Ethylhexylglycerin provide enhanced preservation performance compared to single-component systems. Ethylhexylglycerin increases microbial membrane permeability, allowing Phenoxyethanol to work more efficiently at lower concentrations.
This synergy makes Phenoxyethanol and Ethylhexylglycerin one of the most reliable preservative systems in modern cosmetic formulations.
The combination of Phenoxyethanol and Ethylhexylglycerin delivers effective protection against:
Gram-negative bacteria
Gram-positive bacteria
Yeast
Mold
Phenoxyethanol provides the primary antibacterial effect, while Ethylhexylglycerin boosts overall antimicrobial performance. This makes Phenoxyethanol and Ethylhexylglycerin suitable as a standalone preservative system for many water-based cosmetic products.
Phenoxyethanol and Ethylhexylglycerin are widely recognized for their mild and skin-friendly profile. Compared with traditional preservatives, this system shows lower irritation potential when used at recommended levels.
Because Ethylhexylglycerin also functions as a skin-conditioning agent, Phenoxyethanol and Ethylhexylglycerin are frequently used in:
Sensitive skin products
Baby care formulations
Leave-on skincare
This balance between safety and efficacy has driven the widespread adoption of Phenoxyethanol and Ethylhexylglycerin in modern cosmetic preservation.
One of the major technical advantages of Phenoxyethanol and Ethylhexylglycerin is their wide pH effectiveness range.
Phenoxyethanol and Ethylhexylglycerin remain stable and effective across pH 3 to 10, making them suitable for:
Acidic facial serums
Neutral creams and lotions
Alkaline rinse-off products
This pH flexibility simplifies formulation development and reduces the need for additional preservative systems.
Phenoxyethanol and Ethylhexylglycerin are compatible with a wide variety of cosmetic systems, including:
Emulsions (O/W, W/O)
Surfactant-based cleansers
Alcohol-containing products
Low- and high-viscosity formulations
They integrate smoothly into creams, lotions, gels, serums, and wipes without negatively affecting appearance, texture, or fragrance.
Thanks to their versatility, Phenoxyethanol and Ethylhexylglycerin are widely used across multiple cosmetic and personal care categories.
Facial serums
Moisturizers
Anti-aging creams
Eye-area products
Shampoo
Conditioner
Hair masks and treatments
Facial cleansers
Micellar water
Makeup removers
Baby lotions
Gentle cleansers
Sensitive-skin formulas
Personal care wipes
Cosmetic wipes
Natural-positioned hygiene products
Phenoxyethanol and Ethylhexylglycerin perform well in both leave-on and rinse-off formulations, making them a highly adaptable preservative solution.
Many brands aim to reduce preservative load while maintaining microbiological safety. Phenoxyethanol and Ethylhexylglycerin support this strategy by offering:
High antimicrobial efficacy at low dosage
Multifunctional ingredient benefits
Simplified ingredient labeling
As a result, Phenoxyethanol and Ethylhexylglycerin are commonly used in preservative-light and modern clean-label cosmetic formulations.
Phenoxyethanol and Ethylhexylglycerin are globally approved cosmetic ingredients and comply with major cosmetic regulations, including:
This global acceptance allows cosmetic manufacturers to use Phenoxyethanol and Ethylhexylglycerin in products intended for multiple international markets.
The performance of Phenoxyethanol and Ethylhexylglycerin depends on product purity, stability, and consistency.
