Lauramide DEA (Lauric Diethanolamide) - CAS 120-40-1

Lauramide DEA (Lauramide DEA) CAS 120-40-1: Chemical Aspects

1. Chemical Characteristics

Lauramide DEA is a secondary amide: the structure contains an amide group fragment linked to a C₁₂ hydrocarbon chain and a diethanolamine residue. This structure makes the molecule amphiphilic, suitable for reducing surface tension.

2. Properties

Formula: ~C₁₆H₃₃NO₃

Appearance: High-viscosity liquid or slightly solid mass at room temperature

Solubility: Emulsifies fats, soluble in ethanol, partially miscible with water

Flash point: ~150–180°C

Storage: Avoid direct light and excessive moisture

3. Main Areas of Application

Foam stabilization: Significant action in a range of detergents.

Emulsifier: In creams and lotions, helps combine aqueous and oil phases.

Thickener: Correction of rheological properties of cosmetic compositions.

4. Safety and Control

Skin-allergic reactions: In case of exceeding permissible standards, irritation may occur.

Nitrosamine compounds: Measures to prevent their formation are important (strict production control).

Environmental aspects: The compound is permissible in most countries, with reasonable compliance with disposal standards.

5. Conclusion

Lauramide DEA remains an important auxiliary surfactant in the household chemicals and cosmetics industries, imparting better foaming and viscosity properties to products. At the same time, it is necessary to strictly comply with technological requirements to minimize potential health risks.
