Euxyl® K 903 is a liquid cosmetic preservative, which can be used in leave-on and rinse-off products as well as for wet wipes. It was developed for use in cosmetic formulations with a skin-friendly pH value of up to 6. This product is particularly effective in non-ionic systems. Euxyl® K 903 has a broad, balanced spectrum of effect against bacteria, yeasts and mold fungi as well as a good vapor phase effectiveness.

Microbiological effectiveness
Euxyl® K 903 has a broad, balanced spectrum of effect against bacteria, yeast and mold. It is a typically biostatic product with the biocidal properties necessary for practical use.
Good production hygiene, as well as the use of raw materials with low microorganism levels as a result of correct raw material control are, of course, vital prerequisites for the production of microbiologically faultless finished products. Euxyl® K 903 bridges the gap between efficacy and nature in modern preservation.

Microbiological effectiveness
euxyl® K 903 is equally effective against bacteria, yeast and mold. It is a typically biostatic product with the biocidal properties necessary for practical use. Good production hygiene, as well as the use of raw materials with low microorganism levels as a result of correct raw material control, are of course vital prerequisites for the production of microbiologically faultless finished products.
Temperature stability
When using euxyl® K 903, prolonged heating periods (max. 4 hours) >80°C should be avoided. It is advantageous to add euxyl® K 903 in the cooling phase, e.g. with the fragrance (t <40°C). As a result of the low surface tension of euxyl® K 903 solutions, good dispersion can be expected in most formulations, even at low temperatures.
pH stability
euxyl® K 903 is adapted for use in products with a skin-friendly pH value of up to 6. The efficacy of euxyl® K 903 depends on the pH value. The efficacy is increased by reducing the pH value. pH values exceeding 6 can occur in the production process without affecting the integrity of euxyl® K 903. However, the pH value of the finished product must be checked at the end of the production process and, if necessary, adjusted to max. 6 to activate the preservative efficacy of euxyl® K 903. The pH measurement of a W/O emulsion is problematic. In this case, the measurement must be performed in the water phase, prior to emulsification.
Emulsions
Emulsions may be preserved with 0.4 – 1.2% euxyl® K 903.
Solutions
For shampoos, bath preparations and hand cleansing preparations, good preservation results are achieved with 0.4– 1.2% euxyl® K 903.
Wet wipes
For wet wipes, good preservation results are achieved with 0.4 – 1.2% euxyl® K 903.
euxyl® K 903 is fully effective in anionic, cationic and nonionic systems.
Compatibility with surfactants
euxyl® K 903 was proven to have good compatibility with anionic surfactants such as sulfates, ether sulfates, sulfosuccinates and nonionic surfactants. Compatibility with sulfite ions
Please check the compatibility in individual cases.
Foaming behavior
In a foaming test in accordance with DIN 53 902, a 0.8% solution of euxyl® K 903 in demineralized water proved to be non-foaming.
Solubility
euxyl® K 903 has limited solubility in water. 100 g of water at 20°C dissolve 1.2 g of euxyl® K 903. In polar solvents, such as 1,2-propylene glycol, propanol or
acetone, euxyl® K 903 is readily soluble.
In polyalcohols, such as glycerol and sorbitol, euxyl® K 903 is moderately soluble.
In aliphates with hydrophilic groups, such as 2-octyldecanol and isopropyl myristate, euxyl® K 903 has limited solubility. It is slightly soluble in pure aliphatic solvents.
