Secondary Alcohol Ethoxylate-9

Secondary Alcohol Ethoxylate (9 mol EO) is a specialized non-ionic surfactant derived from a unique secondary carbon structure (where the hydroxyl group is positioned centrally on the carbon chain). This structural distinction grants it superior biodegradability compared to conventional linear alcohol ethoxylates, with a degradation rate exceeding 95% within 28 days. With 9 moles of ethylene oxide and an HLB value of approximately 12-13, it offers moderate hydrophilicity combined with distinctive low-foaming characteristics.

Optimized for Industrial Spray and Metal Cleaning
Its low-foam profile makes it the ideal candidate for high-turbulence applications, such as high-pressure spray cleaners and food processing equipment sanitation, where foam control is critical to prevent pump cavitation and residue. In metal degreasing, it rapidly penetrates and strips heavy oils from mechanical surfaces. Crucially, its superior rinsing properties ensure a "spot-free" finish, leaving metal surfaces clean without streaks or water marks.

Textile and Paper Processing Efficiency
In the textile industry, it serves as a low-foam scouring agent. It effectively removes natural waxes from fabrics without generating excessive foam, thereby preventing the "foam spots" or uneven dyeing defects often caused by traditional surfactants. In the paper industry, it functions as a high-efficiency deinking agent, facilitating the separation of ink from fibers to significantly enhance pulp whiteness and paper quality.

Advanced Technical Attributes: Wetting and Handling
Beyond basic cleaning, the secondary alcohol structure provides significant handling advantages. Firstly, it exhibits superior wetting speeds compared to primary alcohol ethoxylates (like AEO-9), allowing for faster surface coverage. Secondly, it features a narrower gel range and lower pour point. This means it is less likely to form thick, unmanageable gels when mixed with water and remains fluid at lower temperatures, greatly simplifying the dilution and manufacturing process for industrial formulators.
