Isomeric Tridecyl Alcohol Polyether E-1306 (CAS: 9043-30-5) is prepared by addition polymerization of isomeric tridecyl alcohol and ethylene oxide (6EO). It appears as a colorless to slightly yellow transparent liquid. The branched alcohol structure in its molecule gives the product unique interfacial activity, enabling it to rapidly reduce oil-water interfacial tension and form a stable emulsion system, while also exhibiting significant suspension and dispersion capabilities on the surfaces of solid particles and dirt.
Compared with traditional linear alcohol polyether products, E-1306, leveraging the steric hindrance effect of the branched alcohol, has a lower pour point and superior low-temperature fluidity, making it less prone to solidification in cold environments and easier to handle. Its faster dynamic surface tension reduction rate means it performs particularly well in quick cleaning and high-efficiency penetration scenarios – it can rapidly penetrate into substrate surfaces and tiny crevices for deep cleaning. Moreover, the product maintains stable activity over a wide pH range and has excellent hard water resistance, performing well even in water containing calcium and magnesium ions.
Another major advantage of E-1306 is its low odor and low foam characteristics, making it very suitable for formulating high-quality industrial cleaning products. At the same time, it has good compatibility with anionic, cationic, and other nonionic surfactants, offering high formulation flexibility. The product has good biodegradability, meeting increasingly stringent environmental regulations, making it a reliable choice for green formulation systems.

E-1306 has a wide range of applications. Below are the core application suggestions for various fields:
Safety Protection: This product is classified as Serious Eye Damage/Eye Irritation (Category 2). The signal word is "Warning" and the hazard statement is H319 – Causes serious eye irritation. During handling, must wear chemical safety goggles or face shield. After operation, thoroughly wash the skin of any contacted areas.
Storage Conditions: It is recommended to maintain the storage temperature between 5 °C and 40 °C. Store in a cool, dry, well-ventilated warehouse. Keep containers tightly closed and away from incompatible materials such as strong oxidizers, strong acids, and strong alkalis. Use compatible packaging materials such as stainless steel, polyethylene, or polypropylene.
Emergency Procedures: If in eyes, immediately rinse with plenty of running water for at least 15 minutes (P305+P351+P338). If irritation persists, seek medical attention immediately (P337+P313). Ensure good ventilation in the operating area. Keep away from heat sources, sparks, and open flames. No smoking.
