OP-30 is a high-performance nonionic surfactant, with core characteristics including excellent emulsifying power, superior wetting and penetrating properties, efficient dispersing and detergency, and outstanding chemical stability. It is widely used in multiple industrial fields such as pesticides, textiles, cleaning, emulsion polymerization, and more.
Detailed Description
OP-30 Octylphenol Polyoxyethylene Ether (CAS: 9036-19-5) appears as a white to light yellow waxy solid or paste, belonging to nonionic surfactants. Its molecular structure combines hydrophilic groups (polyoxyethylene chain) and hydrophobic groups (octylphenyl), and this unique amphiphilic structure endows the product with excellent comprehensive surface activity, enabling it to play a key functional additive role in various industrial formulations.
The core advantage of this product lies in its high efficiency and excellent compatibility. It can be well compounded with anionic, cationic, and other nonionic surfactants, significantly improving the quality and production efficiency of formulated products. At the same time, the product has high active content and minimal batch-to-batch performance variation, providing reliable assurance for precise formulation of end products.
OP-30 shows outstanding chemical stability, maintaining excellent performance even in high-concentration acid, alkali solutions, and hard water environments. It is not prone to react with calcium and magnesium ions in water to form precipitates, and its applicable working conditions are wide. This characteristic enables it to function reliably under harsh industrial conditions.
