Isomeric alcohol polyether E-1303 (CAS No.: 9043-30-5) is a nonionic surfactant prepared by ethoxylation of isomeric tridecanol. Its unique branched hydrophobic structure endows the product with excellent interfacial activity. With outstanding emulsifying ability, remarkable wetting and penetrating properties, and low foaming characteristics, this product has become an indispensable and efficient component in many industrial formulations, widely serving multiple industry sectors.
In industrial formulations, E-1303 maintains excellent chemical stability in a wide range of acidic, alkaline media, and hard water environments. It is compatible with anionic, cationic, and other nonionic surfactants, providing great flexibility for complex formulation design. Its low foaming tendency gives it a significant advantage in cleaning processes that require rapid rinsing.
| Industry sector | Specific process/application | Product function |
|---|---|---|
| Industrial and household cleaning | Hard surface cleaning, water-based metal cleaners, textile degreasing agents | Provides excellent wetting, penetration, and emulsification capabilities, effectively removing oil and stubborn stains, suitable for high-concentration and diluted cleaning products |
| Textile printing and dyeing | Scouring, penetration, leveling processes | Acts as a key component in scouring agents, penetrating agents, and leveling agents, promoting full fiber wetting and rapid penetration of working fluids, improving dye uptake and dyeing uniformity, reducing color spots and color differences |
| Leather processing | Degreasing, soaking processes | Exhibits excellent emulsifying and penetrating performance, rapidly emulsifying natural fats inside leather, helping tanning agents, fatliquors, and dyes penetrate evenly, improving finished leather quality |
| Pesticide formulations | Emulsifiable concentrates (EC), suspension concentrates (SC), oil-in-water emulsions (EW), etc. | Used as emulsifier and wetting-dispersing agent, enhancing the spreading and adhesion of pesticide liquid on plant leaf surfaces, improving pesticide utilization and control efficacy |
| Emulsion polymerization | Emulsion polymerization of vinyl acetate, acrylates, and other systems | As a nonionic emulsifier, effectively reduces interfacial tension between monomer and water, ensuring smooth polymerization, and imparting good mechanical and storage stability to the synthetic latex |
| Cosmetics and personal care products | Creams, lotions, makeup removers, and other formulations | Serves as a co-emulsifier and solubilizer, helping to build a fine and stable emulsion system, improving product spreadability and post-application skin feel |
When designing formulations, the ethoxylation degree (3EO) of E-1303 gives it a low HLB value, making it particularly suitable as a water-in-oil (W/O) emulsifier or for use in combination with high-HLB surfactants. In metal cleaning formulations, it is recommended to use it in synergy with nonionic or anionic auxiliaries to achieve optimal degreasing and low-foaming effects. In pesticide formulations, it can serve as a core component of the emulsifier system to help build stable emulsions.
It is recommended to conduct small-scale optimization tests based on different process conditions (temperature, pH, electrolyte content, etc.) to determine the optimal dosage. Store the product at 5°C-40°C, avoid freezing or exposure to high temperatures, and seal the container immediately after use to prevent moisture absorption.
