Question

Cocamide DEA/CDEA 6501-92%, what are the main components of Ninol?

Answer

The main component of Cocamide DEA/CDEA 6501-92% (Ninol) is Cocamide DEA (CAS: 68603-42-9), with an active matter content of no less than 92%.

Detailed Description

Cocamide DEA, trade name Ninol, chemical name coconut fatty acid diethanolamide or cocoyl diethanolamine. It is a nonionic surfactant produced by condensation reaction of natural coconut oil with diethanolamine. According to the Guoli Chemical product database, its general molecular structure is C₁₁H₂₃CON(CH₂CH₂OH)₂ and other mixtures, with an average molecular weight of approximately 287.

This product is a pale yellow to amber transparent viscous liquid. Due to the high-purity synthesis process, the active matter content reaches ≥92%, significantly higher than the common 80% specification on the market (such as CDEA 6501-80%). This means the proportion of the effective ingredient—coconut fatty acid diethanolamide—is higher, leading to superior core performance in thickening, foam stabilization, and detergency. Apart from the main component, the product contains only trace amounts of free diethanolamine (≤1.0%) and water (≤1.0%), highlighting its purity advantage.

The chemical structure of Cocamide DEA combines hydrophilic diethanolamide groups and hydrophobic long-chain coconut fatty acid groups, giving it excellent surface activity. It effectively reduces the surface tension of water, providing outstanding thickening, foam stabilization, emulsification, detergency, and antistatic functions in formulations. It also has excellent compatibility with anionic, cationic, and amphoteric surfactants, making it an indispensable multifunctional additive in daily chemical, personal care, and industrial cleaning formulations.

Application Recommendations

Due to the high active matter content of 92%, this product offers significantly better thickening efficiency and foam stability compared to standard grades, especially in the following applications:

  • Premium shampoos, body washes, hand soaps—Adding 1% to 5% provides ideal viscosity and fine, dense foam, while imparting a moisturizing feel and reducing the irritation of primary surfactants.
  • Dishwashing detergents, kitchen heavy-duty degreasers—Works synergistically with anionic surfactants (e.g., AES, LAS) to significantly enhance oil removal and foam persistence. Recommended dosage: 2% to 8%.
  • Industrial degreasing and decontamination agents—As an emulsifying and dispersing component, effectively removes heavy oils from metal and hard surfaces. Can be used in combination with solvents and other nonionic surfactants.
  • Textile printing and dyeing auxiliaries, metalworking fluids—Used as a scouring penetration component or lubricating emulsifying component to improve process effects.

Precautions

  • Safety Warning: This product contains trace amounts of free diethanolamine (DEA), classified as a Group 2B possible human carcinogen by the International Agency for Research on Cancer (IARC). Wear protective gloves and goggles during handling, and avoid direct contact with skin and eyes. Do not use under nitrosating conditions (e.g., in the presence of nitrites in an acidic environment) to prevent the formation of carcinogenic nitrosamines.
  • Storage Requirements: Store in a cool, ventilated place at 10–40°C, seal tightly to prevent moisture. Solidification or stratification may occur at low temperatures, which is a normal physical phenomenon. The product can still be used normally after warming to room temperature and stirring evenly, without affecting performance.
  • Formulation Compatibility: Its nonionic nature makes it widely compatible with various surfactants. However, its thickening effect is particularly pronounced in high-salt formulations. It is recommended to determine the optimal dosage through small-scale trials.
