Euxyl® K 900 is a liquid cosmetic preservative based on benzyl alcohol and ethylhexylglycerin. The addition of ethylhexylglycerin affects the interfacial tension at the cell membrane of microorganisms, improving the preservative activity of benzyl alcohol. Its use is permitted both in products that remain on the skin as well as in rinse-off products. Euxyl® K 900 has a broad, balanced spectrum of effect against bacteria, yeasts and mold fungi.

Euxyl® K 900 is equally effective against bacteria, yeasts and mold fungi. It is a typically biostatic product with the biocidal properties necessary for practical use.

Euxyl® K 900 is stable to hydrolysis, temperature and pH.  It is effective in pH ranges up to 12.

Euxyl® K 900 has good chemical compatibility with anionic surfactants such as sulphates, ether sulphates and sulphosuccinates, as well as with non-ionogenic surfactants.  Ethoxylated surfactants may lead to a loss of effectiveness.

The  tocopherol in Euxyl® K 900 is GMO-free and complies with the criteria of NATRUE and COSMOS (including Ecocert) for natural products.

Applications

Euxyl® K 900 is recommended for use in multiple personal care products including shower gels, shampoos, body washes, creams, lotions, and wet wipes.  It is not suitable for anhydrous products.
