Euxyl 9010

Euxyl® 9010 is a widely used, modern cosmetic preservative system developed to provide reliable broad-spectrum antimicrobial protection in personal care and cosmetic formulations. It is designed to protect products from contamination by bacteria, yeast, and mold, helping maintain product safety, quality, and shelf life throughout manufacturing, storage, and consumer use. Because it is paraben-free and formaldehyde-free, Euxyl® 9010 is especially suited for today’s clean-label and globally compliant cosmetic products.

INCI Name: Phenoxyethanol (and) Ethylhexylglycerin

Chemical Composition & CAS Numbers:

• Phenoxyethanol – CAS No. 122-99-6

• Ethylhexylglycerin – CAS No. 70445-33-9

Euxyl® 9010 is supplied as a clear, colorless to pale yellow liquid with a mild, characteristic odor. It is easily incorporated into water-based and emulsified systems and shows excellent compatibility with most cosmetic ingredients. The preservative system remains effective across a wide pH range (approximately 3.0–10.0) and is stable under normal cosmetic processing temperatures, making it suitable for both hot- and cold-process formulations.

The effectiveness of Euxyl® 9010 comes from the synergistic action of its two components. Phenoxyethanol acts as the primary antimicrobial agent, disrupting microbial cell membranes and inhibiting bacterial growth. Ethylhexylglycerin enhances this activity by increasing cell membrane permeability and reducing surface tension, allowing the preservative system to work efficiently at relatively low concentrations. In addition, Ethylhexylglycerin provides mild skin-conditioning benefits, contributing to improved formulation tolerance.

Typical usage levels of Euxyl® 9010 range from 0.5 to 1.0%, depending on the formulation type, water activity, packaging, and regional regulatory requirements. It is commonly used in a wide variety of applications, including creams, lotions, serums, gels, shampoos, conditioners, body washes, facial cleansers, and sunscreens.

One of the key advantages of Euxyl® 9010 is its minimal impact on product aesthetics. It does not significantly affect viscosity, color, clarity, or fragrance, making it ideal for clear gels and fragrance-forward formulations.

Overall, Euxyl® 9010 is a trusted, effective, and versatile preservative system that supports modern cosmetic formulation needs while ensuring product safety and stability.
