Unraveling the specifications of Amida 60

Just like other important surfactants in the industry, such as Sodium Lauryl Ether Sulfate 27%, Cocoamido Propyl Betaine 30% and Coconut Fatty Acid Diethanolamine 90%, Coconut Fatty Acid Diethanolamine 60%, better known as Amide 60 requires special attention to its residue specifications and active concentration.

On the market, it is not always easy to find analysis reports that detail the active content of Amide 60. Generally, the documents present information on the free amine content and the acidity index, leaving other important aspects aside.

Read on to find out more.

Production of Amide 60

Amide 60 is the result of the reaction between Diethanolamine and vegetable oil, palm kernel oil (PKO) is the most used. The synthesis process prevents the final product reaching concentrations greater than 80-85% Diethanolamide. To obtain higher concentrations, it is necessary to use a different synthesis route, starting the fatty acid ester rather than directly palm kernel oil.

During the reaction, the oil is transformed into fatty acids and glycerin. The fatty acid reacts with diethanolamine, leaving a glycerin residue in the final product. To guarantee the effectiveness of the reaction, it is necessary to add excess Diethanolamine, which results in a residual free Diethanolamine, present in the suppliers' analysis reports.

Furthermore, there is always a residual free fatty acid in the final product, even with excess Diethanolamine. Therefore, it is essential to control the acidity index, which may indicate the presence of an excess of this residual, affecting the solubility of Amide 60 and the quality of the reaction.

The reality of the market: concentrations below expectations

Unfortunately, market practice does not always reflect what is expected. Over the years, Macler has monitored and analyzed the products available on the market, finding that the commonly sold Amides 60 contain around 50% final active ingredients. This situation is the result of the addition of water and Glycerin to the final product, to help stabilize the product and inhibit its crystallization. 

Against this backdrop, Macler began to recommend the use of Amide 90, which was more difficult to obtain so few manufacturers were able to guarantee this concentration. However, this is also currently suffering supplies below the expected concentration, generally between 80 and 85%.

Macler's commitment: transparency and quality

Just as it did with Sodium Lauryl Ether Sulfate 27% and Cocoamido Propyl Betaine 30%, Macler is concerned with clarifying the situation with Amide 60.

Maintaining its commitment to transparency and helping customers and partners to enrich their technical knowledge of their own business, Macler effectively declares the percentage of Diethanolamide concentration in its analysis reports.

In order to remain attractive and allow fair competition with other suppliers, Macler has set its Diethanolamide specification at a minimum of 50%, as is market practice.
