Widely used in household detergents, metal cleaners, and automotive shampoos, it performs effectively across moderate temperatures and blends well with other surfactants . It should be stored in cool, dry conditions .
Product Advantage
Superior Wetting & Emulsifying EfficiencyWith a wetting time of only 60 seconds on cotton fabrics (tested per AATCC 197 standard) and emulsification particle size ≤100nm for silicone oil, E-1008 outperforms conventional surfactants. Its branched isodecyl structure enables rapid penetration into oil stains and tough residues, making it ideal for high-efficiency cleaning. In industrial degreasing tests, it increased oil removal rate by 35% compared to alkylphenol ethoxylates, ensuring thorough and fast cleaning results.
Excellent Environmental Compliance & BiodegradabilityFree of APEO (Alkylphenol Ethoxylates), E-1008 meets EU REACH and US EPA environmental standards. Its biodegradation rate exceeds 90% within 28 days (tested per OECD 301B), causing no harm to aquatic ecosystems. This feature helps customers upgrade their products to "green formulations," avoiding trade barriers in eco-sensitive markets and enhancing brand sustainability competitiveness.
Outstanding Compatibility & pH StabilityIt exhibits strong compatibility with anionic, cationic, and other non-ionic surfactants, with no gel phase issues in mixed systems. In pH 5-9 ranges (common in detergents and coatings), its performance retention rate is over 95%, maintaining stable wetting and dispersing effects. This flexibility allows it to be widely used in diverse formulations, reducing R&D costs for customers' product development.
Exceptional Low-Temperature Fluidity & Freeze-Thaw ResistanceWith a pour point of -8℃ (tested per ASTM D97), E-1008 remains fluid even in cold environments (-5℃ to 0℃), eliminating the need for heating during winter production. After 5 freeze-thaw cycles (-20℃ to 25℃), its active content loss is less than 2%, ensuring consistent quality across seasons. This advantage significantly improves production efficiency in low-temperature regions.
High Electrolyte Tolerance for Industrial ScenariosIn solutions containing 5% NaCl (simulating industrial hard water), E-1008 still maintains 90% of its original emulsifying capacity, far higher than the industry average of 65%. This makes it suitable for metal degreasing, ultrasonic cleaning, and pesticide formulations—scenarios where electrolytes (e.g., metal ions, salts) are common. It ensures stable performance without reducing cleaning or dispersion effects.
Precise Quality Control & Batch ConsistencyOur E-1008 has a minimum active content of 99% (tested by GC), with HLB value controlled at 14.0±0.2 and cloud point at 56-60℃ (1% aqueous solution)—all parameters showing batch-to-batch variation ≤1%. We implement ISO 9001 quality management, conducting 12 quality inspections per production lot. This reliability reduces customers' production risks and ensures stable product performance.

Product Uses
Textile Dyeing & Finishing
As a penetrant and refining agent component, it shortens cotton fabric wetting time to ≤60s, boosting oil-stain removal efficiency by 35%. Its neutral pH (6.0-7.5) avoids fiber corrosion, Adapt to low-temperature dyeing processes, and blends well with other auxiliaries to enhance fabric whiteness and softness.
Household & Industrial
DetergentsIdeal for concentrated laundry detergents and hard-surface cleaners. Its O/W emulsification (particle size ≤100nm) rapidly strips oil, while low foam ensures easy rinsing. APEO-free and 90% biodegradable, it meets green detergent standards, suitable for eco-friendly product lines.
Metal Cleaning & Degreasing
Excels in ultrasonic cleaning and metal degreasing. With ≥90% emulsifying capacity retention in 5% NaCl (hard water), it removes machining oil without residue. High flash point (≥180℃) ensures safe use, and low pour point (-8℃) maintains fluidity in cold workshops.
Agrochemical Formulations
Acts as a pesticide synergist and wetting agent. Its strong penetration helps pesticides adhere to crop surfaces, improving absorption. Compatible with pesticide active ingredients, it resists electrolyte interference (common in agricultural sprays) and complies with environmental regulations for safe field use.
Coatings & Inks
Serves as a wetting and dispersing agent in water-based coatings/inks. It stabilizes pigment dispersion, preventing sedimentation, and its viscosity (300-500 mPa·s) eases blending into formulations. Ensures uniform coating film formation and enhances product storage stability.
Usage & Handling Guide
1、Mixing: Add E-1008 to water (20-40℃ recommended) with stirring (500-800 rpm) until fully dissolved; avoid direct high-temperature heating.
2、Dosage: Use 0.5-5% (by weight) based on application—1-3% for detergents, 2-5% for metal cleaning, 0.5-2% for textiles.
3、Safety: Wear gloves/eye protection; rinse with water if in contact with skin/eyes.
4、Storage: Keep sealed in cool (10-30℃), dry place; avoid sunlight and incompatible chemicals (strong acids/bases).
FAQ
1、Q: What if E-1008 doesn't dissolve well in water?
A: Ensure water temperature is 20-40℃ (not too low) and stir at 500-800 rpm. If still undissolved, check if the product is within shelf life—expired items may have poor solubility. Avoid mixing with cold water directly.
2、Q: Can E-1008 be mixed with strong acids or alkalis?
A: No. It's stable only in pH 5-9. Mixing with strong acids/bases will break its structure, reducing performance. If accidental mixing occurs, discard the solution and restart with a neutral system.
3、Q: Why does the product's color change slightly after storage?
A: Slight off-white tint (from colorless) is normal if stored properly (10-30℃, sealed). It doesn't affect performance. But if it turns yellow/brown, it may be exposed to sunlight or high temps—do not use.
4、Q: Is it safe to adjust the dosage beyond the recommended 0.5-5%?
A: Not recommended. Exceeding 5% may cause excessive foam or residue; below 0.5% leads to weak performance. Adjust only within the range based on your specific application (e.g., 1-3% for detergents).
