1.Product Property
EL series are pale-yellow to amber viscous liquids or soft pastes, miscible with most organic solvents and dispersible in water. They exhibit excellent emulsifying, dispersing and lubricating power across a wide pH range (4–10) and remain stable up to 100 °C.
2.Technical Norm

| EL-20 | pale-yellow liquid | 85–100 | 30–40 | 1.0 | 5.0–7.0 | 9–10 |
| EL-40 | amber liquid/paste | 70–85 | 70–80 | 1.0 | 5.0–7.0 | 13–14 |
| EL-60 | amber soft paste | 55–70 | 85–95 | 1.0 | 5.0–7.0 | 15–16 |
| EL-80 | amber solid | 45–55 | > 100 | 1.0 | 5.0–7.0 | 17–18 |
3.Application Scope and Usage
EL series are widely used as emulsifiers and lubricants in synthetic-fibre spinning oils, textile softeners, pesticide emulsifiable concentrates, pharmaceutical emulsions, metal-working fluids and household detergents. Typical dosage is 1–5 % of the final formulation.
