Superior Corrosion Protection & Emulsification
Scientific testing demonstrates the exceptional performance advantages of our EDIPA products in critical industrial applications.
Corrosion Inhibition Performance
ASTM G31 testing demonstrates exceptional corrosion protection, with a 92% reduction in corrosion rate for carbon steel in aggressive acidic environments.
| System | Corrosion Rate (mpy) | Protection Efficiency |
|---|---|---|
| Blank (5% HCl) | 480 | - |
| EDIPA-15 (1%) | 38 | 92% |
| EDIPA-30 (1%) | 42 | 91% |
Corrosion Rate Comparison
EDIPA forms a protective film on metal surfaces through adsorption and chelation mechanisms, providing excellent barrier protection.
Emulsification Capability
Droplet size measurements following high-pressure homogenization (10,000 psi, 3 cycles) demonstrate the superior emulsification capabilities of our EDIPA products.
| Oil Type | EDIPA-15 (HLB 12) | EDIPA-30 (HLB 15) |
|---|---|---|
| Mineral Oil | 1.8 μm droplet | 2.3 μm droplet |
| Soybean Oil | 2.5 μm droplet | 1.9 μm droplet |
| Silicone (50 cSt) | 3.1 μm droplet | 4.0 μm droplet |
HLB-Application Matching
- EDIPA-15 (HLB 12-13): Optimal for mineral oil emulsification, metalworking fluids and general-purpose industrial applications
- EDIPA-30 (HLB 15-16): Superior for vegetable oil emulsification, concrete additives and high water-content systems
Low-Foaming Advantage
Ross-Miles foam test (ASTM D1173) using 0.1% aqueous solutions at 25°C. EDIPA's unique structural balance provides excellent emulsification without the excessive foaming typically associated with surfactants.
Application Expertise & Usage Recommendations
Precise application guidance for optimal performance across diverse industrial and cosmetic formulations.
Industrial Applications
Metalworking Fluids
Concrete Additives
Agrochemical Emulsifiers
Metalworking Fluid Optimization
Problem
Excessive foaming during high-speed machining operations
Solution
Replace conventional ethoxylated amines with EDIPA-15 at 5-7%
Problem
Poor corrosion protection with hard water
Solution
Add EDIPA-15 at 3% with 0.5% calcium sulfonate
Formulation Tip:
For optimal performance in metalworking fluids, add EDIPA to the oil phase first at 40-50°C, then slowly add the aqueous phase while mixing. This prevents inversion and ensures consistent emulsion quality.
Cosmetic Applications
Hair Relaxers
Cream Bases
Depilatories
Ingredient Compatibility
EDIPA may develop slight color over time in formulations at pH >9. This can be mitigated by adding 0.1% sodium metabisulfite or other suitable antioxidant.
