Isomeric Tridecanol Polyether E-1306 is a high-performance nonionic surfactant produced by the addition polymerization of ethylene oxide with isomeric tridecanol as the initiator. It is widely used in industrial cleaning, textile printing and dyeing, leather processing, metalworking fluids, pesticide formulations, and emulsion polymerization.

Detailed Description

Isomeric Tridecanol Polyether E-1306 (CAS No.: 9043-30-5) is a nonionic surfactant manufactured by Hai'an Guoli Chemical Co., Ltd. It appears as a colorless to slightly yellow transparent liquid. Its molecular structure features isomeric tridecanol as the hydrophobic group, with the addition of 6 moles of ethylene oxide (EO) to form a hydrophilic chain segment, endowing the product with excellent interfacial activity.

Compared with linear alcohol polyether products, Isomeric Tridecanol Polyether E-1306, with its branched structure, has a lower pour point and better low-temperature fluidity. It is less likely to solidify in cold environments, making operation more convenient. Additionally, its molecular structure enables a faster reduction of dynamic surface tension and stronger wetting and penetration capabilities, particularly outstanding in rapid cleaning and efficient penetration scenarios.

This product exhibits excellent acid, alkali, and hard water resistance, good compatibility with anionic, cationic, and other nonionic surfactants, and favorable biodegradability, meeting increasingly stringent environmental regulations. It is an ideal choice for green formulation systems.

Application Recommendations

Industrial and Institutional Cleaning: Used for formulating metal surface cleaners, hard surface cleaners, vehicle cleaners, etc. With excellent wetting, emulsifying, and degreasing abilities, it provides outstanding detergency and anti-redeposition effects, especially suitable for low-foam formulations.

Textile Printing and Dyeing Auxiliaries: As a key component of pretreatment wetting agents, leveling agents, and soaping agents, it promotes the uniform diffusion of dye liquor into fibers, improving fabric treatment uniformity and color fastness. It is also applicable in desizing, scouring, and other pretreatment processes.

Metalworking Fluids: Used as an emulsifier and lubricity additive in cutting fluids and grinding fluids. Suitable for fully synthetic, semi-synthetic, and emulsifiable formulations, it combines cooling, lubrication, and cleaning functions.

Pesticide Formulations: As a pesticide emulsifier for preparing emulsifiable concentrates, emulsion concentrates, and microemulsions, it significantly improves the wetting and spreading of the spray liquid on leaves and field efficacy.

Emulsion Polymerization: Provides stable emulsification and dispersion during the emulsion polymerization of monomers such as acrylates and styrene, helping to control particle size, reduce gel formation, and improve the storage stability of the final latex.

Precautions

This product is classified as a severe eye irritant (GHS Category 2), with the signal word "Warning" and hazard statement H319 – Causes serious eye irritation. Wear chemical safety goggles or face shields during operation and thoroughly wash exposed skin after handling. Recommended storage temperature is between 5°C and 40°C, away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases. If in eyes, rinse immediately with plenty of running water for at least 15 minutes and seek medical attention promptly.
