Can be used to modify alkyd resin, as well as textile additives, paper additives, chemical fiber oil agent synthesis or compounding.
Basic information
Chemical formula: C₁₁H₂₃CON(CH₂CH₂OH)₂
Molecular weight: 287.16
Abbreviation: CDEA
Trade name: 6501, Ninal
Appearance: Light yellow to amber thick liquid
CAS number: 68603-42-9
Physical property
Solubility: Easily soluble in water, forming an opaque fog-like solution in water at first, which can be completely transparent after stirring. At a certain concentration, it can be completely dissolved in various surfactants, including low carbon and high carbon surfactants.
Stability: With good foaming, foam stability, penetration decontamination, hard water resistance and other functions.
Synthesis method
Direct synthesis of fatty acid and diethanolamine: the process is simple, but the cost is high and there are many side reactions, so it is rarely used.
One step process: Direct reaction of refined oil with diethanolamine. The cost of this method is low, but the product color is deep, the alkanolamide content is only about 70%, the competitiveness in the international market is insufficient, and the domestic small and medium-sized manufacturers are mostly used.
Two-step process: The laurate was formed by transesterification of coconut oil with alcohol, and then the product was formed by reaction with diethanolamine. This is the methyl ester method, the reaction temperature is low, the resulting product color, good transparency, high thickening performance, laurate diethanolamide content can reach more than 85%, the raw material cost is comparable to the one-step method, the product competitiveness is strong, but the process is complex, involving methanol dispersion, labor protection, fire protection and other issues, equipment investment, late management requirements are strict.
Use
Detergent field: can strengthen the cleaning effect, often used as an additive, foam stabilizer, foaming agent, a large number of shampoo, liquid detergent and other manufacturing.
Other applications: can be used to modify alkyd resin, as well as textile additives, paper additives, chemical fiber oil agent synthesis or compounding.
Matters needing attention
Storage conditions: Should be stored in a cool and ventilated place, avoid direct sunlight and high temperature.
Safety: Wear protective equipment such as gloves and masks during operation to prevent direct contact with skin and eyes.
Compatibility: Before mixing with other chemicals, it is necessary to perform compatibility tests to avoid adverse reactions or reduce the effect.
FAQ
1.How to properly use cosmetics containing CDEA?
The correct use of cosmetics containing CDEA should pay attention to the following points:
Before use
Understanding skin type: Different skin types have different reactions and needs to cosmetics.
