Product Advantage
Stable & Compatible Properties
MPEG-450 maintains excellent stability under heat and common solvents (water, alcohols), with a 1% aqueous solution pH of 5.0–7.0 (neutral range) that avoids corrosivity. This ensures high compatibility with other ingredients in formulations, reducing risk of phase separation or degradation.
Precise Technical Specifications
Controlled hydroxyl value (115–135 mgKOH/g) and strict appearance standards (clear liquid at 25°C) guarantee batch-to-batch consistency—critical for industrial production accuracy. Our supply meets 99%+ purity benchmarks, supporting reliable end-product quality.
Easy Handling & Storage
As a low-viscosity liquid, MPEG-450 is simple to measure, transfer, and blend in manufacturing processes. It’s non-flammable, stores safely in dry, ventilated areas (shelf life: 2 years), reducing logistics and storage costs for clients.
Broad Formulation Adaptability
Its non-ionic nature avoids ionic interference in mixed systems, making it suitable for both acidic and neutral formulations. This flexibility eliminates the need for additional pH adjusters in most applications, streamlining production.

Product Uses
Cosmetics & Skincare
MPEG-450 acts as a softener and viscosity regulator in lotions, creams, and serums. Its solubility and mildness help improve product texture, ensuring even ingredient dispersion while enhancing skin-feel (non-greasy, lightweight).
Chemical & Polymer Synthesis
It serves as a raw material for polymer modification (e.g., with acrylic acid/methacrylic acid) to produce MPEG-based polymers—key components in cement water reducers, boosting concrete workability and strength.
Textile & Coating Auxiliaries
In textile processing, MPEG-450 functions as a dispersant and lubricant, improving dye uniformity and fiber smoothness. In coatings, it enhances emulsion stability and film-forming properties, reducing surface defects.
MPEG-450 can be directly added to formulations during mixing (room temperature or mild heating <60°C for faster dissolution). For high-viscosity systems, pre-dissolve it in water/alcohol first, then blend gradually. Avoid contact with strong acids/bases to preserve stability. Seal unused portions to prevent moisture absorption.
FAQ
What's the shelf life of MPEG-450?
It has a 2-year shelf life when stored in original, sealed packaging in dry, ventilated areas (avoid direct sunlight and extreme temperatures).
Is MPEG-450 compatible with ionic ingredients?
Yes—its non-ionic nature allows compatibility with most ionic (anionic/cationic) and non-ionic materials, with no adverse reactions in neutral/weakly acidic systems.
Can MPEG-450 be used in food-related applications?
No, our MPEG-450 is industrial-grade and not formulated for food contact; it's intended for cosmetics, chemicals, and textiles.
