Isooctanol Polyoxyethylene Ether EH-03 (CAS 26468-86-0) is a high-performance nonionic emulsifier, derived from isooctanol and ethylene oxide (3mol EO addition).
It excels in emulsification, dispersion, and solubilization, with strong stability against acids, alkalis, and hard water, plus low skin irritation. Widely applied in daily chemicals (detergents, skincare), industry (paints, metalworking fluids), and textiles (dyeing auxiliaries), it enhances formulation stability and product efficacy. Available in industrial or cosmetic grades, it meets diverse application needs.
Product Advantage
Superior Emulsification Efficiency with Stable Performance
Isooctanol Polyoxyethylene Ether EH-03 features 3mol ethylene oxide (EO) addition, enabling it to reduce oil-water interfacial tension by over 35% in 5 minutes—significantly faster than conventional emulsifiers. It maintains stable emulsified systems for 6+ months at temperatures ranging from -5℃ to 60℃, with no phase separation even in pH 4-10 environments, ensuring consistent performance in harsh conditions.
Low Irritation & High Safety Compliance
With a skin irritation index of ≤0.8 (tested per OECD 404 standards), this emulsifier is far below the industry average of 1.5, making it safe for cosmetic and personal care formulations. It complies with REACH Regulation (EC No. 1907/2006) and FDA 21 CFR 178.3400, meeting global safety standards for both industrial and daily chemical applications, eliminating regulatory concerns for international clients.
Excellent Compatibility & Multipurpose Adaptability
It exhibits over 98% compatibility with anionic, cationic, and other nonionic surfactants, as well as common raw materials like pigments, oils, and solvents. This versatility allows it to be used in 10+ industries—from paint (reducing pigment sedimentation by 40%) to metalworking fluids (improving lubricity by 25%)—without requiring formula adjustments, cutting R&D time for clients.
High Purity & Consistent Quality Control
Produced via a closed-loop etherification process, the product achieves a purity of ≥99.5%, with impurity content (such as free isooctanol) ≤0.3%—lower than the industry limit of 0.8%. Our factory holds ISO 9001 and ISO 14001 certifications, with 100% batch testing (including viscosity, pH, and emulsification rate) to ensure each shipment meets uniform quality standards.
Cost-Effective Dosage & Long Shelf Life
Compared to similar emulsifiers, EH-03 requires a 15-20% lower dosage (typically 0.5-2% of total formulation) to achieve optimal emulsification, reducing clients' raw material costs. Additionally, it has a 24-month shelf life (when stored in sealed containers at room temperature), minimizing inventory waste and ensuring long-term usability.

Product Uses
1、Daily Chemical Industry
Used in detergents (laundry liquid, dish soap) to emulsify oil stains and disperse dirt, reducing residue. In skincare (lotions, creams) and shampoos, it stabilizes oil-water systems, lowers irritation, and improves product texture for better skin/massage feel.
2、Coatings & Inks Industry
Acts as an emulsifier and dispersant in water-based paints/inks. It disperses pigments evenly, prevents sedimentation, enhances coating adhesion, and ensures consistent color. Also reduces paint viscosity, making application smoother with fewer brush marks.
3、Metalworking Industry
Added to metalworking fluids (cutting oil, grinding fluid) to emulsify mineral oil, improve lubricity. It forms a stable oil film on metal surfaces, reducing friction/wear, and resists hard water to maintain fluid performance in long-term use.
4、Textile Industry
Serves as a wetting and dyeing auxiliary. It enhances fabric wetting speed, ensures uniform dye adsorption, avoids color spots, and improves color fastness. Compatible with textile auxiliaries, suitable for cotton, polyester, and blended fabrics.
5、Food & Pesticide Fields
Food-grade variants (compliant with FDA 21 CFR 178.3400) stabilize emulsions in beverages/dairy. In pesticides, it disperses active ingredients, improves spray adhesion on crop leaves, and boosts pesticide efficacy while reducing environmental waste.
Product Operate Guide
For general use: Add EH-03 to the formulation (dosage 0.5-2% of total weight) at 25-40℃. Stir at 300-500 RPM for 5-10 minutes until fully dissolved. Avoid high temperatures (>60℃) to prevent performance loss. For different industries: Adjust dosage slightly (e.g., 1-1.5% for detergents, 0.8-2% for paints) and test compatibility with other raw materials first to ensure optimal results.
FAQ
1、Q: How should I store EH-03 to maintain its quality?
A: Store it in a sealed, cool, and dry place (5-30℃) away from direct sunlight and strong oxidants. Unsealed containers should be used up within 3 months to avoid moisture absorption affecting performance.
2、Q: Can EH-03 replace other nonionic emulsifiers like AEO-3 in formulations?
A: Yes, it can. EH-03 has similar emulsifying ability but lower irritation. However, test compatibility with your specific raw materials first, as dosage may need minor adjustments for optimal results.
3、Q: Is EH-03 safe for use in children's skincare products?
A: With a skin irritation index ≤0.8 (OECD 404), it's low-irritant. But ensure the final product meets local children's cosmetic regulations and conduct additional safety tests if required.
4、Q: What if EH-03 causes slight turbidity in the formulation?
A: Turbidity may occur due to low temperature. Warm the formulation to 25-30℃ and stir gently—this usually resolves it. If not, check if the dosage or compatibility with other ingredients is correct.
5、Q: Does EH-03 have a shelf life, and what happens if it expires?
A: Its shelf life is 24 months from production. Expired EH-03 may have reduced emulsifying efficiency or slight color change, so it's not recommended for use to avoid affecting product quality.
