The usage of Cocamide DEA varies by application field. Choose the appropriate addition stage and formulation method to achieve optimal thickening, foam stabilization, and detergency.

Detailed Explanation

Cocamide DEA (6501) is a widely used nonionic surfactant, primarily water-soluble, and can be diluted with water at room temperature. In most formulations, it is used together with anionic surfactants (e.g., AES, LAS) and exhibits a significant synergistic effect. It is generally recommended to add it under stirring at a temperature of 40-60°C. If necessary, it can be premixed with hot water (approximately 60°C) before being added to the mixing tank. Avoid prolonged heating above 120°C.

This product has an active content of 80%. In formulations, it is typically used as an important auxiliary component for thickening, foam stabilization, and emulsification, rather than as the primary surfactant. The dosage can be fine-tuned based on the viscosity and foam requirements of the target product to achieve the desired performance.

Cocamide DEA is most commonly used in personal care products and household cleaning products. The typical procedure involves adding it slowly after the primary surfactants have been fully dissolved, with continuous stirring to ensure complete dispersion and emulsification. If common formulation issues such as unsatisfactory foam or low product consistency occur, first consider adjusting its dosage rather than blindly replacing other formulation components.

Application Recommendations

Recommended Dosage (Based on general industry experience, for reference only; actual dosage should be determined through formulation trials):

Key Usage Points:

  • Add during the mixing phase of the formulation, control temperature at 40-60°C, pour slowly and stir thoroughly until completely dissolved and dispersed.
  • If viscosity reduction is needed for easier metering, preheat with warm water at 50-60°C or predilute before addition.
  • Generally used as an auxiliary component; it does not compete with primary surfactants. On the contrary, it exhibits significant synergistic effects when combined with anionic surfactants such as AES and LAS.
  • Use small batch trials to find the precise addition amount suitable for your formulation to achieve the target consistency and foam performance.

Precautions

  • The product is slightly alkaline (1% aqueous solution pH 8.5-10.5). Wear chemical protective gloves and goggles during operation and avoid direct contact with skin and eyes.
  • Do not store or use together with strong oxidizers, strong acids, or nitrites to prevent the formation of N-nitroso compounds.
  • Avoid prolonged heating above 120°C during processing to prevent decomposition or generation of harmful substances.
  • Recommended storage temperature is 5°C~40°C. At low temperatures, the product may thicken or solidify. In such cases, place the container in warm water to slowly warm it up and restore fluidity before normal use.
  • The dosage ranges above are based on general industry experience. Specific dosages should be determined through trials based on the formulation system.
