C13 Alcohol Polyether E-1340 is a high-performance nonionic surfactant of isotridecanol polyoxyethylene (13) ether, widely used in various industrial fields such as textile, cleaning, leather, papermaking, coatings, pesticides, metalworking, and emulsion polymerization due to its excellent emulsifying, wetting, penetrating, and dispersing properties.

Detailed Description

C13 Alcohol Polyether E-1340 (CAS No.: 9043-30-5), chemical name: isotridecanol polyoxyethylene (13) ether, also known as Isotridecanol Ethoxylate (13EO), PEG-13 Isotridecyl Ether, Trideceth-13, etc. The product appears as a colorless to slightly yellow transparent liquid or paste, belonging to nonionic surfactants.

The core characteristic of this product lies in its unique molecular structure—formed by the addition of isotridecanol with 13 ethylene oxide (EO) units, giving it both hydrophilic and lipophilic properties. It maintains stable chemical performance in both acidic and alkaline environments, tolerates hard water conditions, and has a very wide range of applicability. With excellent emulsifying ability, it can form stable and fine emulsion systems for various oil phases; at the same time, it has rapid wetting and penetrating properties, significantly reducing surface tension and promoting the spreading and penetration of liquids on substrate surfaces.

As a high-quality product of Hai'an Guoli Chemical Co., Ltd., C13 Alcohol Polyether E-1340 plays a key role in industrial formulations and is an indispensable surfactant component in many fine chemical products.

Main Applications

1. Textile Printing and Dyeing Auxiliaries — Used as scouring agents, penetrants, and leveling agents, providing excellent wetting, penetrating, and dispersing properties during fabric pretreatment and dyeing processes, helping to remove impurities and ensure uniform dye uptake, improving fabric quality.

2. Industrial and Institutional Cleaners — As a surfactant component in hard surface and metal cleaning, effectively emulsifying and dispersing oil stains, suitable for cleaning hard surfaces such as kitchens, bathrooms, and industrial metal parts, with low foam and easy rinsing characteristics.

3. Leather Processing Auxiliaries — In the degreasing process, it powerfully removes natural fats from raw hides, while also acting as an emulsifying carrier for fatliquoring agents, promoting uniform penetration of oils and fats, making the leather soft and full.

4. Paper Chemicals — Used as a component in deinking agents to promote separation of ink from fibers and prevent redeposition; it can also clean paper machine felts, removing adhered resins and impurities, extending felt life.

5. Waterborne Coatings and Inks — As a wetting and dispersing agent, it quickly wets pigment and filler particles in waterborne systems, stabilizes dispersions, prevents flocculation and sedimentation, improving storage stability and color performance of coatings and inks.

6. Agrochemicals — As an emulsifier for pesticide emulsifiable concentrates and as a tank-mix wetting synergist, it reduces the surface tension of spray liquid, enhances wetting, spreading, and penetration on plant leaves and target surfaces, improving efficacy.

7. Metalworking Fluids — It provides lubrication, cooling, and cleaning effects in semi-synthetic or full-synthetic cutting fluids; it can also serve as a component in alkaline cleaners to quickly remove machining oils from metal surfaces, with anti-rust effects.

8. Emulsion Polymerization — In emulsion polymerization of monomers such as acrylates and styrene, it acts as a primary or co-emulsifier, providing excellent micellar solubilization and particle size control, generating fine and stable polymer emulsions.
