Euxy K 903 is a mild and effective preservative for modern cosmetic formulations with a pH up to approximately 6. It provides broad, balanced spectrum protection against bacteria, yeasts and moulds, works well in non-ionic systems and has good efficiency in the vapour phase. It is suitable for leave-on, rinse-off and wet wipes and is easily incorporated into aqueous or aqueous-glycol bases.
In contaminated systems, allow a minimum contact time of approximately 48 hours for complete disintegration of micro-organisms. Observe production hygiene and use raw materials with a low microbial load. Store in the original sealed container at room temperature, protected from heat and direct light.
Works best in the "skin-friendly" range up to approximately 6. Lowering the pH usually increases its effectiveness, so we recommend fine-tuning the finished product to pH ≤ 6.
Yes. It has good vapor phase efficacy and a balanced spectrum of protection, making it suitable for both wet wipes and delicate formulations when the recommended pH and dosage are followed.
Pre-dissolve it in an aqueous-glycol phase (e.g. propylene glycol), add to the aqueous phase while cooling below 40°C and mix until homogeneously distributed. Avoid prolonged heating above 80 °C.
Most commonly 0,5-1,0 % (overall range for practice 0,4-1,2 %). Adjust the choice of dose to the type of product.
