Product Advantage
Superior Stability & Low Volatility
MPEG-1500 maintains thermal stability (even under high-temperature processing) and extremely low vapor pressure, ensuring consistent performance in long-term storage and harsh industrial conditions. Its pH stability (5.0–7.0 in 1% solution) avoids acid-base-induced degradation.
Excellent Compatibility
This non-ionic compound blends seamlessly with water, ethanol, and organic solvents. Our factory produces it with a hydroxyl value control precision of ±2 mgKOH/g, guaranteeing batch-to-batch consistency for formulation reliability.
Low Toxicity & Biocompatibility
With strict quality control (purity ≥99%), MPEG-1500 meets cosmetic and pharmaceutical-grade safety standards, making it suitable for skin-contact products (e.g., creams, lotions) without irritation risks.
Multi-Functional Performance
It acts as both a moisturizer (locking moisture for 8+ hours in cosmetic tests) and a thickener, simplifying formulation processes by replacing multiple additives—reducing production costs for our clients.

Product Uses
Cosmetics & Personal Care
MPEG-1500 serves as a base material and viscosity regulator in creams, lotions, and hair care products. Its moisturizing properties enhance skin hydration, while its mildness suits sensitive skin formulations.
Agrochemicals
It functions as an emulsifier in pesticide formulations, improving the solubility and stability of active ingredients. This ensures uniform dispersion of pesticides, boosting their effectiveness in field applications.
Construction Materials
When copolymerized with acrylic acid, MPEG-1500 produces polycarboxylate superplasticizers—key additives for high-performance concrete, enhancing workability and strength.
For cosmetic formulations: Add 2–5% MPEG-1500 to the water phase, heat to 70–80°C, and stir until fully dissolved before mixing with the oil phase. For pesticide emulsions: Blend 3–8% with active ingredients and solvents, then homogenize for 10–15 minutes to ensure stability. Store unused product in a dry, ventilated area.
FAQ
What's the shelf life of MPEG-1500?
It has a 2-year shelf life when stored in sealed packaging under dry, cool conditions (avoid direct sunlight and moisture).
Is MPEG-1500 compatible with ionic surfactants?
Yes, its non-ionic nature allows stable mixing with both cationic and anionic surfactants, suitable for complex formulations.
Can MPEG-1500 be used in food-related products?
No, it is designed for industrial, cosmetic, and agrochemical use—we do not recommend food applications.
