P65
Jienuo
Propylene glycol block polyether P65 (also called PPG block polyether P65, CAS 9003-11-6) is a high-performance nonionic surfactant & copolymer. As a key industrial auxiliary, it excels in emulsification, dispersion, and low-foam stabilization. Widely used in coatings, pesticides, textiles, and detergents, it offers strong compatibility with water-based/oil-based systems, good thermal stability, and low toxicity. Its versatile properties make it ideal for enhancing product uniformity, reducing processing viscosity, and improving formulation efficiency in various manufacturing applications.
Product Advantage
Outstanding Technical Stability
It maintains stable performance across 5.0–7.0 pH and up to 85°C (cloud point), with ≤1.0% moisture content—ensuring consistent quality in long-term storage and harsh processing conditions (e.g., high-temperature coating production).
High Compatibility
As a nonionic surfactant, it blends seamlessly with both water-based and oil-based systems, avoiding phase separation in formulations (e.g., pesticide emulsions or textile auxiliaries).
Multi-Functional Performance
It integrates emulsification, dispersion, and anti-static properties: for example, 0.3% addition in wool processing boosts fiber strength by 10% and reduces breakage rate (tested in industrial applications).
Low Toxicity & Eco-Friendliness
Compliant with general industrial safety standards, it's suitable for low-toxicity scenarios (e.g., food-contact detergents) without harmful residues.

Product Uses
Textile Industry
Added (0.3% dosage) in wool finishing: it reduces fiber damage, enhances strength, and acts as an anti-static agent to improve processing efficiency.
Pesticide Formulations
Serves as an emulsifier/dispersant: it stabilizes pesticide mixtures, ensuring uniform distribution and improving active ingredient efficacy.
Coatings & Inks
Works as a low-foam dispersant: it reduces viscosity in water-based coatings, enhancing product uniformity and application smoothness.
Detergent Manufacturing
Used in low-foam detergents: it boosts decontamination power while minimizing foam buildup in industrial cleaning processes.
Add P65 directly to the formulation during mixing (temperature ≤80°C for optimal stability). Adjust dosage based on application: 0.1–0.5% for coatings, 0.3% for textile processing, and 1–3% for pesticide emulsions. Stir thoroughly (10–15 minutes) to ensure full dispersion; avoid contact with strong acids/bases to preserve performance.
FAQ
What's P65's shelf life?
It has a 2-year shelf life when stored in sealed, cool (room temperature), and ventilated conditions (away from moisture and direct sunlight).
Is P65 compatible with food-contact products?
Yes, its low-toxicity profile makes it suitable for food-contact detergents (compliant with general safety standards).
Can P65 replace PE series products?
Absolutely—it's a cost-effective alternative to PE series polyethers, with comparable or better emulsification/dispersion performance.
