C13 alcohol polyether E-1340, with the chemical name isotridecanol polyoxyethylene (13) ether (CAS No.: 9043-30-5), is a nonionic surfactant. The product appears as a colorless to slightly yellow transparent liquid or paste, formed by the addition polymerization of isotridecanol with ethylene oxide (13 EO). Its unique branched hydrophobic group structure gives it a lower pour point and better low-temperature fluidity compared to linear alcohol ethers, while maintaining high surface activity.
The core advantage of this product lies in its "multi-functional single agent": it can act as an efficient emulsifier to stably disperse oil phases in water, as a strong wetting and penetrating agent to rapidly reduce liquid surface tension and promote spreading and penetration on substrates, and as a dispersant to effectively prevent aggregation and sedimentation of solid particles. Additionally, the ether bonds in its molecular structure give the product good chemical stability, allowing it to maintain stable performance under acidic, alkaline, and hard water conditions, making it extremely versatile.
In the product portfolio of Haian Guoli Chemical Co., Ltd., C13 alcohol polyether E-1340 is positioned as a general-purpose industrial surfactant, covering eight major application areas including textile printing and dyeing, industrial cleaning, leather processing, paper deinking, water-based coatings, pesticide formulations, metalworking fluids, and emulsion polymerization. It is a mature and highly recognized classic product in the market.

Textile Printing and Dyeing: Recommended for formulations of scouring agents, wetting agents, and leveling agents. Its excellent wetting and penetrating properties help remove impurities from fabrics and promote uniform dye uptake. The recommended dosage depends on the specific formulation system, typically 0.1% to 1.0% of the working solution.
Industrial and Institutional Cleaning: Suitable for hard surface cleaners and metal parts cleaning agents. It efficiently emulsifies and disperses oil stains, with low foaming and easy rinsing characteristics. It performs stably in both alkaline and acidic cleaning formulations.
Leather Processing: Used in degreasing and fatliquoring emulsification stages. It powerfully removes natural oils from raw hides while serving as an emulsifying carrier for fatliquoring agents to promote uniform oil penetration, improving leather softness and fullness.
Pesticide Formulations: Acts as an emulsifier component for emulsifiable concentrates and oil-in-water emulsions, and as a wetting enhancer in tank-mix adjuvants to reduce liquid surface tension, enhance spreading and penetration on plant leaf surfaces, and improve efficacy.
Emulsion Polymerization: Serves as a primary or secondary emulsifier in the emulsion polymerization of monomers such as acrylates and styrene. It offers excellent micellar solubilization and particle size control, producing fine and stable polymer emulsions.
