Isotridecyl Alcohol Ethoxylate E1305 is a high-performance nonionic surfactant with optimized ethylene oxide content, offering excellent emulsifying, wetting, and detergency. It works well with various surfactants, stays stable in pH 4.5-9.5 and up to 60℃, and is eco-friendly (≥92% biodegradable in 28 days).
Widely used in cleaning (degreasers, detergents), textiles (dyeing agents), coatings (emulsion stability), and agriculture (pesticide adjuvants), it’s produced under ISO 9001/GMP (purity ≥99%, moisture ≤0.3%) with flexible packaging and global delivery.
Product Advantage
Optimized EO Content for Superior PerformanceWith precisely calibrated ethylene oxide (EO) content, this surfactant delivers exceptional emulsifying and wetting capabilities. In tests, its 0.1% aqueous solution reduces surface tension to ≤30 mN/m, enabling 30% faster penetration into tough stains compared to standard ethoxylates—ideal for high-efficiency cleaning and textile dyeing.
Broad Environmental StabilityIt maintains consistent functionality across a pH range of 4.5-9.5 and temperatures up to 60℃, with no performance degradation even after 72 hours of continuous use. This stability eliminates formulation limitations, making it suitable for both acidic metal cleaners and alkaline household detergents.
Eco-Friendly & Safe ComplianceCertified to meet OECD 301B standards, it achieves ≥92% biodegradability within 28 days, far exceeding industry averages. It also has low aquatic toxicity (LC50 >100mg/L for freshwater fish), ensuring compliance with EU REACH and US EPA regulations for eco-friendly product formulations.
High Purity & Reliable QualityProduced under ISO 9001 and GMP guidelines, it boasts a purity of ≥99% and moisture content ≤0.3%—tested via HPLC and Karl Fischer methods for every batch. This low impurity level reduces formulation inconsistencies, with 98% of customers reporting no batch-to-batch performance variations.
Versatile Compatibility & Formulation FlexibilityIt blends seamlessly with anionic (e.g., sodium lauryl sulfate), cationic (e.g., cetyltrimethylammonium chloride), and other nonionic surfactants. This compatibility allows it to be used in 80% of industrial and household formulations, from pesticide adjuvants to water-based coatings, without compatibility issues.

Product Uses
1、Heavy-Duty Cleaning Industry
Its low surface tension (≤30.0 mN/m) enables quick penetration into oil stains. Added to industrial degreasers (3-5% dosage) or automotive cleaners, it breaks down tough lubricating oil and grease, leaving no residue on metal parts—ideal for mechanical maintenance.
2、Textile Dyeing & Finishing
As a wetting agent (0.8-2% dosage), it ensures even dye distribution on cotton/polyester fabrics. Its stable performance in pH 4.5-7.0 prevents color spots, improving dye fastness by 15-20% and enhancing fabric softness after processing.
3、Water-Based Coatings & Inks
Mixed into coatings (1-3% dosage), it boosts emulsion stability—preventing pigment sedimentation during storage. This ensures smooth application on wood/metal surfaces and enhances coating adhesion.
4、Agricultural Pesticide Formulations
Added to pesticides (0.5-1.5% dosage), it improves spray adhesion on crop leaves. Its strong wetting ability (wetting time ≤12.0s) helps pesticides spread evenly, increasing crop absorption rate by 25% and reducing chemical waste.
Product Operate Guide
For cleaning: Add 3-5% to water (20-40℃), stir until dissolved, then apply to stains. For textiles: Mix 0.8-2% with dye solution, stir gently, then use for dyeing. For coatings: Blend 1-3% into coatings, stir well. For pesticides: Add 0.5-1.5% to dilutions, shake 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 for cleaning?
A: Heat water to 30-40℃ (not over 50℃), add the product slowly while stirring continuously. If still undissolved, check water pH—adjust to 4.5-7.0 to promote full dissolution.
2、Q: Can I increase the dosage beyond recommended ranges for better results?
A: For most scenarios, don't exceed 5% (cleaning) or 2% (textiles). Higher dosages may cause excess foam or formulation instability; test a small batch first if adjustments are needed.
3、Q: How to handle accidental contact with skin/eyes during use?
A: Rinse skin with plenty of water for 10 minutes. For eyes, flush with water for 15 minutes and seek medical help if irritation persists—avoid rubbing to prevent further discomfort.
4、Q: Does the product expire, and how to tell if it's gone bad?
A: It has a 24-month shelf life. If it turns cloudy, develops a strange odor, or loses solubility, it may have degraded—discard and use a new batch for optimal performance.
