How is Stearic acid amide emulsion made?
What is Stearic acid amide emulsion?
Stearic acid amide emulsion is a white emulsion. The product is non-toxic, non-polluting, non-hazardous, and environmentally friendly. It is used in inks, paints, leather coatings, etc.
Stearic amide is also called ceramide. Its chemical formula is C17H35CONH2. Stearic acid amide is insoluble in water and slightly soluble in organic solvents at room temperature. It can improve the dispersion effect and affinity of dyes and pigments.

More about Stearic acid amide emulsion
1. It has no hygroscopicity, good smoothness, can improve the dispersion effect of pigments and dyes, and has lubricity and demoulding properties.
2. This product is white or yellowish faded powder. After recrystallization in ethanol, it is a colorless leaf crystal. Soluble in hot ethanol, chloroform, and ether, insoluble in cold ethanol, and insoluble in water. The lubricity is lower than that of fat, and the durability is shorter. The thermal stability is poor, and it has initial coloring. The above disadvantages can be overcome by mixing with a small amount of higher alcohols (C16-18).
preparation of Stearic acid amide emulsion
Because stearic amide is insoluble in water, an emulsifier and dispersant need to be added in the process of preparing water-based stearic amide emulsion to achieve a dispersion effect. Even if an emulsifier and dispersant are added to the existing water-based stearate emulsion, the dispersion effect is still poor, and it is easy to precipitate, and flocculation and stratification may occur after long-term storage. In addition, the existing method needs high-speed stirring and grinding under heating conditions in the process of preparing water-based stearate emulsion, which has a complex production process and high production cost. Preparation method of water-based stearic acid amide: firstly, add stearic acid amide and emulsifiers A and B into the water and stir for 60 minutes (stirring speed is 2500 rpm), then add defoamer and preservative and stir for 40 minutes (stirring speed is 2500 rpm) to obtain water-based stearic acid amide emulsion. The prepared water-based amide stearate emulsion has a solid content of 41.7% by weight and a viscosity of 146 mPa·S; The water-based stearic amide emulsion was centrifuged at 20000 rpm for 30 minutes, and no delamination was found. Stearic acid amide emulsion was kept at 20-35℃ for 3 months without flocculation and delamination.
Price of Stearic acid amide emulsion
Stearic acid amide emulsion particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Stearic acid amide emulsion. A large amount of large amount will be lower. The price of Stearic acid amide emulsion can be found on our company's official website.
