Product Advantage
Excellent Compatibility & Solubility
MPEG-400 is miscible with water, ethanol, and organic solvents, while its non-ionic nature ensures high compatibility with most formulation ingredients. This reduces ingredient conflict risks in multi-component systems.
Stable Performance
It features thermal stability and low volatility (no steam pressure), maintaining consistent properties in neutral environments. Its pH (5.0-7.0) and hydroxyl value (128-178 mgKOH/g) meet strict industrial standards, ensuring reliable batch-to-batch quality.
Low Viscosity & Easy Handling
As a low-viscosity liquid (25°C), MPEG-400 is easy to measure, mix, and process—reducing operational complexity in production lines, especially for high-volume formulations.
Multi-Industry Adaptability
Certified for use in cosmetics, pharmaceuticals, and agrochemicals, it balances safety (non-toxic) and functionality, making it a cost-effective choice for cross-industry applications.

Product Uses
Cosmetics & Skincare
It acts as a humectant, softener, and viscosity regulator in lotions, creams, and serums. Its hydrophilicity enhances product texture and skin absorption, suitable for daily care formulations.
Pharmaceutical Excipient
Used as a solubilizer and stabilizer in drug formulations (e.g., oral liquids, topical preparations), it improves the solubility of active ingredients while ensuring biocompatibility.
Agrochemical Formulations
As an additive in pesticide formulations, it aids in emulsification and dispersion, enhancing the stability and efficacy of agricultural sprays.
MPEG-400 can be directly added to formulations during mixing (25-40°C for optimal handling). Adjust dosage based on application: 2-5% for cosmetics, 3-8% for pharmaceutical excipients, and 1-3% for agrochemicals. Avoid contact with strong acids/bases to preserve stability.
FAQ
What is MPEG-400's shelf life?
It has a 2-year shelf life when stored in a dry, ventilated area (25°C, sealed). No quality degradation occurs under proper storage conditions.
Is MPEG-400 safe for cosmetic use?
Yes, it is non-toxic and biocompatible, meeting cosmetic-grade safety standards for direct skin contact.
Can MPEG-400 be mixed with ionic ingredients?
Its non-ionic nature allows compatibility with most ionic and non-ionic ingredients, with no adverse reactions in standard formulations.
