Isotridecanol Polyether E-1306 (CAS No.: 9043-30-5) is a high-performance nonionic surfactant produced by Guoli Chemical. Its molecular formula is C₁₃H₂₇O(C₂H₄O)nH (n≈6), with a molecular weight of approximately 464. This product is synthesized by the addition polymerization of ethylene oxide with isotridecanol as the initiator, belonging to the class of isotridecanol polyoxyethylene ethers. Its unique branched-chain structure imparts a lower pour point and better low-temperature fluidity. Compared to linear alcohol polyether products, it offers a faster dynamic surface tension reduction rate and stronger wetting and penetrating capabilities.
The product is a colorless to slightly yellow transparent liquid, readily soluble in water and most organic solvents. It has an HLB value of approximately 11.5 and a cloud point of 44~46°C (1% aqueous solution), classifying it as a low-foaming surfactant. The synergistic effect of the branched alkyl chain and the polyoxyethylene segment in the molecular structure enables the product to maintain good surface activity over a wide temperature and pH range. It exhibits excellent acid, alkali, and hard water resistance and has good compatibility with anionic, cationic, and other nonionic surfactants.
This product possesses good biodegradability, meeting increasingly stringent environmental regulations. It is widely used in industrial cleaning, textile dyeing and finishing, leather processing, metalworking fluids, pesticide formulations, and emulsion polymerization. It is recommended to store it sealed in a cool, dry, and well-ventilated place at temperatures between 5°C and 40°C.

Based on its HLB value of 11.5 and excellent wetting and emulsifying properties, Isotridecanol Polyether E-1306 is particularly suitable for the following applications: In industrial hard surface cleaning and metal cleaning formulations, a recommended addition amount is 2%~8%; as a wetting agent in textile pretreatment, a recommended dosage is 1~5 g/L; as an emulsifier component in metalworking fluids, a recommended addition amount is 3%~10%; as an emulsifying synergist in pesticide emulsion concentrates, the addition amount is usually 1%~5%. Its low-foaming characteristic makes this product perform excellently in high-pressure spray cleaning and circulating system applications, avoiding operational issues caused by foam accumulation.
