DESCRIPTION
Fatty Acid Diethanolamide is a non-ionic surfactant derived from natural fatty acids and diethanolamine.
Fatty Acid Diethanolamide is known for its excellent foam-boosting and viscosity-building properties.
Fatty Acid Diethanolamide acts as a co-surfactant in various cleaning and personal care products.
Fatty Acid Diethanolamide enhances the stability and texture of liquid formulations.
Fatty Acid Diethanolamide is valued for its compatibility with both anionic and nonionic systems.
Fatty Acid Diethanolamide is biodegradable and often used in eco-friendly formulations.
Fatty Acid Diethanolamide helps create creamy and luxurious textures in shampoos and bath products.
Fatty Acid Diethanolamide can improve the wetting and emulsifying performance in hard-surface cleaners.
Fatty Acid Diethanolamide contributes to cost-effective thickening without additional thickeners.
Fatty Acid Diethanolamide provides stability in a wide pH range, making it versatile for various applications.
Fatty Acid Diethanolamides are generally pale yellow to amber viscous liquids with a faint amine or coconut-like odor.
They are produced by condensation reactions between fatty acid methyl esters (e.g. coconut or palm oil-derived) and diethanolamine at elevated temperatures and alkaline catalysis.
The quality and composition—e.g. free DEA content—vary by molar ratio used (typically 1:1 yields lower free DEA).
These compounds are amphiphilic, enabling both hydrophilic and lipophilic interactions; many are sparingly to fully water‑soluble depending on chain length.
PROPERTIES
Chemical Formula: C₇₊ₙH₁₅₊₂ₙNO₃ (n ~ C₈–C₁₈)
Molecular Weight: ~231–371 g/mol depending on fatty acid content
Appearance: Clear to pale yellow viscous liquid; may darken with age
Odor: Mild amine or coconut note
Density: ~0.99 g/cm³ at 20 °C for coconut-based formulations
Melting Point: ~23–35 °C (solidifies or becomes cloudy near this range)
Boiling Point: ~169–275 °C depending on mixture constituents
Solubility: Miscible in water and alcohols; forms weakly alkaline aqueous solutions
Log P: ~3.5 for cocamide DEA reflecting lipophilicity
Stability: Generally chemically stable; may slowly hydrolyze or produce minor DEA levels under high pH or heat
Storage Conditions: Store sealed at ambient conditions, protect from heat, light, and moisture.
FIRST AID
Inhalation:
Remove to fresh air.
If respiratory irritation occurs, seek medical attention.
Skin Contact:
Wash affected area with soap and water.
Discontinue use if irritation develops; free DEA may contribute to sensitization.
Eye Contact:
Flush eyes thoroughly with water for at least 15 minutes.
Seek medical evaluation if irritation persists.
Ingestion:
Rinse mouth with water.
Do not induce vomiting.
Seek medical attention if significant ingestion occurs.
Note to Physicians:
Treat symptomatically.
Cocamide DEA is classified by IARC as Group 2B (possibly carcinogenic to humans), likely due to free diethanolamine impurity in mixtures rather than pure amide itself.
HANDLING AND STORAGE
Handling:
Use in well-ventilated environments; wear gloves and eye protection.
Avoid prolonged skin contact and inhalation; free diethanolamine impurity may pose irritant hazard.
Spill Response:
Contain spills; absorb with inert material.
Wash area thoroughly and dispose according to local regulations.
Storage:
Store in tightly closed containers in cool, dry place.
Avoid prolonged exposure to heat or light to minimize impurity formation.
Precautions:
Assess free diethanolamine content in batches.
Follow relevant regulations and safety guidance for carcinogenic or sensitizing impurities.
