Euxyl® K 830 – Preservative

Euxyl® K 830 is a highly effective, broad-spectrum cosmetic preservative system designed to protect personal care and cosmetic formulations from microbial contamination, including bacteria, yeast, and mold. It is widely used in modern formulations due to its paraben-free and formaldehyde-free profile, making it suitable for clean-label and globally compliant cosmetic products.

INCI Name

Benzyl Alcohol (and) Dehydroacetic Acid

Chemical Composition & CAS Numbers

• Benzyl Alcohol – CAS No. 100-51-6

• Dehydroacetic Acid – CAS No. 520-45-6

Euxyl® K 830 is supplied as a clear to slightly yellow liquid with a mild characteristic odor. It is easy to formulate and shows good compatibility with a wide range of cosmetic ingredients, making it suitable for both leave-on and rinse-off products.

Functional Description

Euxyl® K 830 works through a dual-action preservation mechanism. Benzyl alcohol provides strong antimicrobial activity, particularly against bacteria, while dehydroacetic acid enhances protection against yeast and mold. Together, these components deliver reliable, broad-spectrum preservation, ensuring product safety throughout its shelf life and during consumer use.

This preservative system is especially valued for formulations that aim to meet natural-leaning or mild preservation claims, as both components are well recognized and accepted in global cosmetic regulations.

Key Benefits

• Easy to incorporate into cosmetic formulations

pH Range & Stability

Euxyl® K 830 performs best in formulations with a pH up to approximately 5.5, making it particularly suitable for skin care, hair care, and personal hygiene products formulated within mildly acidic ranges. It is stable under standard cosmetic processing conditions and can be added during the cooling phase of formulation.

Typical Usage Levels

• 0.8 – 1.2%, depending on formulation type, water activity, and regional regulations

Microbial challenge testing is always recommended to confirm optimal dosage.

Sensory & Formulation Impact

One of the key advantages of Euxyl® K 830 is its low impact on product aesthetics. It does not significantly alter viscosity, texture, or appearance when used at recommended levels. This makes it suitable for transparent gels and emulsions where visual clarity and sensory feel are important.

Regulatory & Safety Information

Euxyl® K 830 is approved for cosmetic use in many regions, including EU, India, and other global markets, when used within permitted concentration limits. On ingredient labels, it must be declared as Benzyl Alcohol (and) Dehydroacetic Acid.

When used correctly, it is considered safe and well tolerated. As with all preservatives, proper formulation testing and regulatory compliance are essential.
