Product Advantage
1. Exceptional Emulsification Efficiency Backed by Data
With a surface tension reduction rate of ≥45% (tested via Wilhelmy plate method), this emulsifier rapidly disperses oil-water phases to form uniform emulsions. It maintains emulsion stability for over 12 months at 25℃ (accelerated aging test), far exceeding industry averages (typically 6-8 months). This ensures end products remain consistent in texture and performance during storage and use, reducing formulation failure risks.
2. Broad Compatibility with Multi-Surfactant Systems
It exhibits 98% compatibility with common anionic (e.g., sodium lauryl sulfate), cationic (e.g., cetyltrimethylammonium chloride), and non-ionic (e.g., fatty alcohol ethoxylates) surfactants (HPLC compatibility testing). Unlike narrow-spectrum emulsifiers, it won't cause phase separation or viscosity fluctuations in mixed systems, supporting flexible formulation designs for diverse industries.
3. High Purity & Customizable Grade Control
Manufactured via a 3-step purification process (molecular distillation + activated carbon adsorption + membrane filtration), it achieves a purity of ≥99.5% (GC analysis), with impurity content (e.g., free isooctanol) below 0.1%. We offer 3 grades (food-grade: FDA-compliant; cosmetic-grade: meets EU CosIng standards; industrial-grade: ISO 9001-certified) to match specific application requirements, ensuring regulatory compliance.
4. Low Irritation & Eco-Friendly Performance
In human skin patch tests (200 subjects, 48-hour exposure), it shows a 0.5% irritation rate—well below the cosmetic industry's 2% safety threshold. It's also readily biodegradable (85% degradation rate within 28 days, per OECD 301B test) and free of banned substances (e.g., parabens, phthalates), aligning with global environmental regulations like REACH and California Prop 65.
5. Cost-Effective Usage with Low Dosage Requirement
Only 0.3-1.2% dosage (based on total formulation weight) is needed to achieve optimal emulsification—30-50% lower than traditional emulsifiers (e.g., sorbitan esters, which require 1.0-2.5% dosage). This reduces raw material costs for manufacturers while maintaining product quality, delivering higher value per unit weight.

Product Uses
1. Cosmetics & Personal Care
In creams and lotions, it emulsifies oil-soluble ingredients (e.g., plant oils, vitamins) with water, preventing separation and keeping textures smooth. For shampoos, it boosts foam stability and helps conditioners spread evenly, reducing scalp irritation (thanks to low-irritation properties).
2. Industrial Cleaning
Added to metal degreasers, it breaks down heavy oil stains on machinery surfaces by emulsifying oil-water mixtures. In household detergents, it enhances dirt-removing efficiency, especially for greasy kitchenware, while remaining compatible with other surfactants.
3. Paints & Coatings
In water-based latex paints, it acts as a dispersant for pigments (e.g., titanium dioxide), stopping sedimentation during storage. It also improves film-forming—resulting in smoother, more even paint coats with better adhesion to walls or metal substrates.
4. Textile Processing
During fabric dyeing, it helps disperse dye molecules evenly in water, avoiding uneven color patches on cotton, polyester, or blended fabrics. It also reduces dye waste by boosting dye absorption, cutting production costs for textile factories.
5. Food Industry
As a food-grade emulsifier, it stabilizes oil-in-water mixtures in dairy drinks (e.g., milkshakes) to prevent cream separation. It's also used in baked goods to improve dough elasticity, making bread softer and extending shelf life—all compliant with FDA standards.
Product Operate Guide
Add EH-40 to your formulation at 0.3-1.2% (based on total weight) – adjust per application (e.g., 0.5-0.8% for cosmetics, 0.8-1.2% for industrial cleaning). Mix with water first, then add oil-soluble ingredients, stirring at 300-500 RPM for 10-15 mins (25-30℃) until uniform. Avoid high temps (>60℃) to keep stability. Store in a cool, dry place (sealed) for up to 24 months.
FAQ
Q1: Can EH-40 be mixed with other emulsifiers?
Yes. It has 98% compatibility with common anionic, cationic, and non-ionic emulsifiers. Mixing can enhance performance (e.g., with sorbitan esters for better stability), but test a small batch first to avoid unexpected viscosity changes.
Q2: What if EH-40 exceeds the recommended dosage?
Overdosing (＞1.2%) may cause slight viscosity increase or surface oil in formulations. It won't affect safety, but it wastes raw materials. Reduce dosage gradually and stir well until the emulsion returns to a uniform state.
Q3: Is EH-40 safe for direct skin contact in cosmetics?
Absolutely. The cosmetic-grade EH-40 has a 0.5% skin irritation rate (tested on 200 subjects) and meets EU CosIng standards. It's mild enough for face creams and baby lotions, with no toxic or irritating residues.
Q4: How to handle EH-40 if it freezes in cold storage?
If frozen, thaw it at room temperature (20-25℃) for 4-6 hours – do not use heating equipment (e.g., microwaves). After thawing, stir gently for 5 mins; its emulsifying performance will remain unchanged, as it's stable at ≤-10℃ (food-grade).
