Product Description

Product Overview: Propylene Glycol Block Polyether L63(CAS 9003-11-6)

Propylene Glycol Block Polyether L63 (also called PPG block polyether L63, CAS 9003-11-6) is a versatile nonionic surfactant and emulsifier. As a polyoxypropylene-polyoxyethylene block copolymer, it offers excellent compatibility, high stability, and low toxicity.

Its core functions include emulsifying, dispersing, and wetting—making it widely used in pesticides (as emulsifiers), coatings, inks, detergents, and chemical formulations. Available in industrial/food grades, it suits bulk industrial applications and high-safety scenarios (e.g., cosmetics, food processing). It's a cost-effective, multi-purpose raw material for global B2B procurement.

Product Advantage

Outstanding Technical Stability
It maintains consistent performance (pH 5.0–7.0, moisture ≤1.0%) across storage and application, with a 2-year shelf life—ensuring reliable quality for long-term production schedules.
Versatile HLB Compatibility
Boasting an HLB value of 11, it integrates seamlessly with diverse formulations (e.g., detergents, emulsifiers), reducing the need for additional compatibility agents.
Low-Toxicity & Wide-Grade Adaptability
Available in industrial-grade variants, it meets safety standards for scenarios like pesticide emulsification and metal processing, with low environmental impact.
Cost-Effective Bulk Supply
Packaged in 200kg/50kg drums, it supports large-scale procurement at competitive prices, ideal for B2B industrial raw material needs.
