Characteristics and Applications

ODEA

Characteristics

Solubility: ODEA disperses well in water and is soluble in common organic solvents.
Performance Characteristics: ODEA is known for its excellent emulsification, antistatic properties, anti-fogging capability, anti-friction characteristics, and rust prevention.

Applications

Oil Additive: ODEA is extensively used as an additive in oils, improving their performance by reducing friction and preventing rust.
Polymer Materials: As an antistatic and anti-friction agent, ODEA enhances the processing and end-use properties of polymer materials, making it a critical component in the plastics industry.
Boiler Cleaning: Its rust prevention and dispersant qualities make ODEA an excellent choice for boiler cleaning formulations, ensuring efficient and long-lasting protection against corrosion.
Fiber Processing: ODEA serves as a lubricant in fiber processing, facilitating smoother operations and improving the quality of the final product.

SDEA

Characteristics

Solubility: SDEA disperses in water, forming a gel, and is soluble in organic solvents.
Performance Characteristics: SDEA offers superior emulsification, lubrication, thickening, opacity, and detergent properties.

Applications

Textile Industry: In textiles, SDEA is used as a lubricant and soft finishing agent, enhancing the feel and quality of fabrics. Its thickening properties are particularly beneficial in textile formulations.
Cosmetics: SDEA acts as an emulsifier and opacifier in cosmetic products such as creams and lotions, improving their texture and stability. Its emulsification ability ensures a uniform distribution of ingredients, enhancing product performance and user experience.

LDEA

Characteristics

Solubility: LDEA disperses well in water and dissolves in organic solvents.
Performance Characteristics: LDEA is noted for its excellent foaming ability, stability, thickening, permeability, rust prevention, and compatibility with other active agents.

Applications

Dyeing Auxiliaries: LDEA is used as a detergent, thickener, foam stabilizer, and corrosion inhibitor in dyeing processes, ensuring high-quality dyeing outcomes and extending the durability of equipment.
Rust Inhibition: Its rust-preventive properties make LDEA an ideal choice for protecting metals such as copper and iron, crucial in various industrial applications.
Personal Care Products: In shampoos, mild detergents, and liquid soaps, LDEA functions as a foam stabilizer and viscosity modifier, improving product performance and user satisfaction.

Packaging and Storage

Packaging Options: Typically packaged in 200 kg iron drums or 50 kg plastic drums.
Storage Conditions: Stored in a cool, dry place, away from direct sunlight and moisture.
Shelf Life: 2 years
