Product Advantage
Stable Technical Performance
With a strictly controlled hydroxyl value (68–83 mgKOH/g) and neutral pH (5.0–7.0 in 1% aqueous solution), MPEG-750 maintains consistent quality across batches—our production adheres to 99% purity standards, ensuring reliable performance in diverse formulations. Its non-ionic nature ensures excellent compatibility with organic/inorganic materials, reducing formulation instability risks.
Low Volatility & Thermal Stability
This product features low vapor pressure and strong thermal stability, making it suitable for high-temperature processing scenarios (e.g., coating curing). Unlike volatile alternatives, it retains functionality even under 80℃ conditions, minimizing material loss during production.
Multi-Functional Utility
Beyond being a surfactant, MPEG-750 acts as a base material and viscosity regulator. Its white solid form (25℃) simplifies storage and metering—we offer 200kg/50kg packaging (flake/block) for flexible handling, aligning with industrial-scale and small-batch production needs.
Low Toxicity & Safety
Classified as a non-hazardous chemical (per transportation standards), MPEG-750 is safe for use in cosmetic/pharmaceutical auxiliary applications. Its low-toxicity profile reduces operational risks, making it compliant with global industrial safety regulations.

Product Uses
Cosmetics & Pharmaceuticals
MPEG-750 serves as a base material and viscosity regulator in cosmetics (e.g., creams) and pharmaceuticals (e.g., ointments). Its neutral pH and low toxicity ensure skin-friendliness, while its emulsifying property helps stabilize formulations, improving product texture and spreadability.
Coatings & Adhesives
In coatings and adhesives, it acts as a formulation aid to enhance film-forming properties. Its thermal stability ensures consistent performance during coating curing, while its compatibility with resins reduces phase separation, resulting in smoother, more durable finishes.
Polycarboxylate Superplasticizer Raw Material
When reacted with acrylic acid, MPEG-750 produces MPEG methacrylate— a core monomer for polycarboxylate superplasticizers (used in concrete). This application leverages its controlled hydroxyl value to optimize the superplasticizer's water-reducing efficiency.
For general formulations: Dissolve MPEG-750 in water/ethanol (ratio: 1:5–1:10) at 25–40℃ (stir gently until fully dispersed). For high-temperature processes (e.g., coating production), add it during the mixing stage (≤80℃) to maintain stability. Store the unused product in a dry, ventilated area (shelf life: 2 years) to preserve its white solid form.
FAQ
What is the packaging of MPEG-750?
We offer 200kg drum (flake) and 50kg carton (block) packaging. Both options are sealed to prevent moisture, suitable for long-distance transportation (classified as non-hazardous chemicals).
Can MPEG-750 be used in food-related products?
No. MPEG-750 is an industrial-grade material, designed for cosmetics, coatings, and construction applications—not for food contact.
What is the shelf life of MPEG-750?
When stored in dry, ventilated conditions (avoiding moisture), MPEG-750 has a 2-year shelf life. Expired products may experience changes in hydroxyl value, so we recommend using them within the validity period.
