Key Ingredients (INCI)
  • Phenoxyethanol
  • Benzyl Alcohol
  • Ethylhexylglycerin
  • Tocopherol (Stabilized with synthetic alpha Tocopherol)
Key Features & Benefits
  • Strong broad-spectrum efficacy
  • Performs well in challenging formulations
  • Vapor phase activity
  • Stable to hydrolysis, temperature, and pH
Microbiological Efficacy Effective against various microorganisms (Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Candida albicans, Aspergillus brasiliensis)
Application Suitable for leave-on, rinse-off, and wet wipes applications. Effective in formulations containing natural raw materials.
Global Approvals Approved for use up to 2.50% in leave-on and rinse-off formulations in regions such as the EU, USA, ASEAN, China, and MERCOSUR.
Solubility Limited solubility in water (7.5 g/L at 20°C); better solubility in polar solvents (eg, propylene glycol) and limited solubility in non-polar solvents.
Stability Stable in formulations up to pH 12, resistant to hydrolysis and temperature fluctuations.
Material Compatibility Compatible with materials such as stainless steel, brass, PE, and PVC. Not recommended for use with PC, PET, or ABS.

Usage: For all types of products that require preservatives.

Mixing method: Mix at any stage, the temperature of the cosmetic must be below 80 °C and the pH must be between 2-12.

Usage rate: 0.5-2.5% (1.0-1.5% is recommended as it is sufficient for most formulas)

Product Description: Clear liquid

Solubility: Soluble in water up to 0.75%, mix with any type of glycol to increase solubility.

Storage: Can be stored at room temperature, but close the bottle tightly and keep away from sunlight or heat. The product has a shelf life of at least 2 years.
