Euxyl K 903 1 L

Premium Liquid Preservative Euxyl K 903 for Advanced Cosmetic and Personal Care Preservation

Modern formulation science requires highly reliable, broad-spectrum preservative systems that ensure product safety without compromising the integrity of sensitive cosmetic bases. Euxyl K 903 is a premium liquid preservative blend specifically designed for challenging surfactant-based products, emulsions, and water-based cosmetics. Composed of a synergistic blend of phenoxyethanol, benzoic acid, dehydroacetic acid, and ethylhexylglycerin, it delivers powerful antimicrobial efficacy against bacteria, yeasts, and molds. This versatile active ingredient functions seamlessly across a wide pH spectrum, making it an indispensable choice for formulators seeking dependable microbial protection in both rinse-off and leave-on formulations.

Across the global cosmetic market, indie brands and large-scale manufacturers increasingly demand paraben-free and formaldehyde-free preservative solutions that meet rigorous international regulatory standards. Euxyl K 903 stands out due to its excellent global acceptance, proven skin compatibility, and minimal impact on product viscosity or fragrance profiles. Developers of professional cosmetics and artisanal laboratories appreciate how easily this liquid additive incorporates into cold or warm processes, guaranteeing batch-to-batch stability and long shelf-life reliability.

Multifunctional Applications Across Diverse Personal Care and Household Sectors

In skincare manufacturing, this specialized preservative protects delicate creams, lotions, and facial toners from microbial spoilage, ensuring safe daily application. Within hair care formulations, it maintains the purity of shampoos, liquid conditioners, and scalp treatments, preventing bacterial growth in high-water environments. The personal hygiene and surfactant industry utilizes its broad antimicrobial activity in liquid soaps, shower gels, and intimate washes, where it performs reliably in complex micellar networks.

For artisanal soap making and home-crafted cleansers, the liquid format ensures uniform distribution throughout the batch without requiring pre-dissolving steps. In the manufacturing of household chemicals and cleaning products, such as dishwashing liquids and surface cleaners, it prevents biological degradation and maintains formula stability. Pharmaceutical topical preparations and cosmetic wet wipe solutions also benefit from its robust preservation capacity, protecting consumer health while maintaining optimal formula pH and physical characteristics.

Botanical Purifying Body Wash

Purified water - seventy milliliters

Cocamidopropyl betaine - fifteen milliliters

Sodium coco sulfate - ten milliliters

Glycerin - three milliliters

Euxyl K 903 - one milliliter

Lavender essential oil - one milliliter

In a sanitized mixing vessel, combine the purified water and glycerin, stirring gently until uniform. Slowly introduce the sodium coco sulfate and cocamidopropyl betaine into the aqueous phase, mixing carefully to prevent excessive foam generation until a clear surfactant base is achieved. Add the lavender essential oil, blending thoroughly until fully incorporated into the liquid. Finally, pour in the Euxyl K 903 and stir continuously for several minutes until the preservative is completely dispersed throughout the mixture. Transfer the finished body wash into a clean dispenser bottle.

The resulting body wash displays a smooth, medium-viscosity fluid texture that dispenses cleanly and produces a rich, velvety lather upon contact with water. It gently cleanses the skin while maintaining optimal moisture levels, leaving behind a subtle botanical fragrance and ensuring long-lasting microbiological stability without causing dryness or irritation.
