Isotridecanol polyoxyethylene ether E-1306 is a nonionic surfactant produced by adding ethylene oxide to isotridecanol as a starting agent. Its hazard mainly lies in eye irritation (GHS Category 2, signal word "Warning", hazard code H319). Under normal use conditions, it is chemically stable, but there is a risk of combustion when exposed to open flames, high heat, or strong oxidizers (auto-ignition temperature approximately 290°C, closed-cup flash point > 100°C).
Operation should follow standardized work practices: maintain general ventilation or local exhaust ventilation in the work area to prevent formation of aerosols or atomized droplets; keep away from heat sources, sparks, open flames, and other ignition sources, and no smoking; handle with care to avoid spills. Do not eat, drink, or smoke during work, and thoroughly wash exposed skin after operation.
Due to the unique branched structure of isotridecanol, this product has a low pour point and excellent low-temperature fluidity, making it resistant to solidification in cold environments. However, it is still recommended to maintain storage temperature between 5°C and 40°C, avoiding extreme high temperatures and direct sunlight. It has good compatibility with anionic, cationic, and other nonionic surfactants, but should be kept away from incompatible substances such as strong oxidizers, strong acids, and strong bases.

Personal Protective Equipment: Wear standard chemical safety goggles or face shields (splash-proof type) during operation, and it is recommended to also wear chemically resistant gloves (e.g., nitrile rubber gloves) and protective work clothing. After operation, thoroughly wash exposed skin in accordance with P264.
Dosage and Compatibility Suggestions: In formulations such as industrial cleaning, textile auxiliaries, and metalworking fluids, the dosage can be determined based on the HLB value matching principle according to the specific application scenario. When compounded with anionic surfactants, it can improve detergency and emulsification efficiency; when used as a primary or auxiliary emulsifier in emulsion polymerization, it is recommended to verify the optimal addition amount and method through small-scale tests.
Dilution and Feeding: The product is dispersible in water. It is recommended to slowly add it to water under stirring conditions, or premix with other surfactants before feeding to ensure uniform dispersion. In winter low temperatures, if viscosity increases or slight turbidity occurs, this is a normal physical phenomenon. Heating to room temperature and appropriate stirring can restore clear fluidity without affecting product performance.
