Applications
1. Personal Care Products
Commonly found in shampoos, body washes, liquid soaps, conditioners, and bath gels.
Functions include:
Foam booster and stabilizer - enhances foam quality when used with anionic surfactants like SLS or SLES.
Viscosity enhancer - increases the thickness and richness of the product.
Emollient - improves the feel of the product on the skin, making it smoother and less drying.
2. Household and Industrial Cleaning Products
Used in dishwashing liquids, laundry detergents, and all-purpose cleaners.
Enhances grease-cutting ability and foam stability, especially in hard water conditions.
Provides wetting and emulsifying properties, aiding in soil and oil removal.
3. Metalworking Fluids and Lubricants
Acts as an emulsifier and corrosion inhibitor in cutting fluids and lubricants.
Helps form stable oil-in-water emulsions and reduces wear on metal surfaces.
4. Textile and Leather Processing
Used as a wetting agent and softener, improving the penetration and feel of textile and leather treatments.
5. Paints, Coatings, and Agricultural Formulations
Serves as a dispersing agent and emulsifier, ensuring homogeneous blending of active ingredients in various industrial formulations.
Benefits
1. Excellent Foam Stability
Strengthens and sustains foam in cleansing products, improving cleaning performance and sensory appeal.
2. Thickening and Rheology Control
Increases viscosity of liquid products without the need for additional thickeners.
3. Mildness and Conditioning
Derived from natural oleic acid, providing skin-compatible properties and reducing irritation from primary surfactants.
4. Emulsifying and Solubilizing Power
Efficiently emulsifies oils and helps solubilize fragrances and other hydrophobic ingredients.
5. Biodegradability
Composed of renewable, plant-derived raw materials, making it more eco-friendly than synthetic alternatives.
Conclusion
Oleic acid diethanolamide (CAS 93-83-4) is a versatile nonionic surfactant used widely in personal care, household, and industrial products. Its ability to stabilize foam, enhance viscosity, emulsify oils, and condition the skin makes it a key component in mild yet effective formulations. With its natural origin, multifunctionality, and biodegradability, it continues to be a valuable ingredient in environmentally conscious and performance-driven products.
