Isotridecyl Alcohol Ethoxylate E1303 is a professional-grade nonionic surfactant with excellent emulsifying, wetting, and detergency abilities. It boasts superior compatibility with anionic, cationic, and other nonionic surfactants, and maintains stable performance across pH 4-10 and varying temperatures.
Low-toxic and biodegradable, it suits eco-friendly product development, widely applied in cleaning (degreasers, detergents), textiles (dyeing wetting), paints (emulsion stability), and agriculture (pesticide adhesion). Produced under ISO 9001 standards with ≥99% purity, it comes in customizable packaging (200L drums, 1000L IBC tanks) for global delivery.
Product Advantage
Exceptional Surface ActivityOur isotridecyl alcohol ethoxylates, formed by the condensation of isotridecyl alcohol and ethylene oxide, exhibit outstanding wetting, permeability, and emulsifying properties. Even when added in small amounts (a few percent in pre-treatment formulations), they enable excellent scouring results, significantly boosting process efficiency.
Versatile Industrial ApplicabilityThese non-ionic surfactants are versatile in multiple industries. In the textile sector, they serve as key components in degreasing, cleaning, emulsifying, and refining agents. In metalworking, they act as effective auxiliaries in multi-functional cleaners, degreasing agents, and ultrasonic cleaners. Their wide range of applications meets diverse industrial needs.
Superior Emulsifying Performance for Specific OilsWhen used with amino 硅油 and dimethyl 硅油，they show exceptional emulsifying effects. Compared to linear alkylphenol emulsifiers, they require less dosage, produce more stable emulsions, and have strong permeability, penetrating deep into fibers to give fabrics a more satisfying soft handfeel.
Eco-Friendly and Convenient to UseFree of benzene ring structures, products made with these surfactants are eco-friendly. Moreover, formulating them into 80 - 90% concentration creates uniform liquids, which are more convenient to use and deliver better results. Also, models like E - 1340, E - 1360, and E - 1380 can replace TX - 40/OP - 40 as environmentally friendly emulsifiers and wetting agents.

Product Uses
As a key additive in industrial degreasers and household detergents, it boosts dirt-removing efficiency. Its strong wetting ability penetrates oil stains quickly, working well with other surfactants to clean metal parts, kitchen surfaces, and fabric stains without residue.
Used in dyeing and finishing processes, it acts as a wetting agent. It reduces solution surface tension, ensuring even dye distribution on fabrics. This improves color fastness and makes textiles softer, suitable for cotton, polyester, and blended fabrics.
3. Paint & Coating Industry
Enhances emulsion stability in water-based paints. It prevents pigment sedimentation, keeps the coating uniform, and improves adhesion to substrates like wood, metal, and walls. This ensures smooth application and long-lasting film performance.
Added to pesticide formulations, it improves spray adhesion on crop leaves. Its emulsifying property keeps pesticides dispersed evenly, boosting absorption by plants. This enhances pest control effects while reducing pesticide waste.
Serves as an auxiliary in metal cleaners and coolants. It removes machining oil from metal surfaces efficiently and helps coolants maintain stability, preventing corrosion and extending the service life of metal workpieces.
Product Operate Guide
For cleaning/metalworking: Add 1-5% of the product to water or base solutions, stir at 20-40℃ until fully dissolved, then use as normal cleaner/coolant.
For textiles/paints: Mix 0.5-3% with dyes/paint components, stir gently to avoid foam, then proceed with dyeing/coating.
For agriculture: Blend 0.2-1% into pesticide dilutions, shake well before spraying. Avoid mixing with strong acids/bases; store in a cool, dry place.
FAQ
1、Q: What if the product doesn't dissolve fully in water?
A: Heat water to 20-40℃ (avoid exceeding 50℃), stir while adding the product slowly. If still undissolved, check if water pH is 5.0-7.0—adjust if needed for full dissolution.
2、Q: Can it be mixed with anionic surfactants?
A: Yes, it has excellent compatibility with anionic, cationic, and other nonionic surfactants. Mix in recommended ratios (per application) for stable, enhanced performance.
3、Q: How long can it be stored, and what conditions are needed?
A: It has a 24-month shelf life when stored in a sealed container, in a cool (10-30℃), dry place away from direct sunlight and strong acids/bases to avoid degradation.
4、Q: If the cleaning effect is poor, how to adjust the dosage?
A: For heavy oil stains, increase the dosage from 1-5% to 5-8% (max 10%), ensure full dissolution, and extend contact time slightly—this usually improves cleaning efficiency significantly.
