Application of Octadecyl Dimethyl Amine Oxide OA-18 :
Detergent: octadecyl dimethyl amine oxide, as the main component of detergent, can effectively reduce the surface tension and increase the wettability and permeability of the solution. It can effectively remove stains and oil stains on clothing, making clothing more clean and tidy.
Cosmetics: octadecyl dimethylamine oxide is also widely used in cosmetics. It can act as an emulsifier, thickener and stabilizer to help the oily and water-based substances in cosmetics mix to form a stable emulsion. At the same time, it can also increase the viscosity and stability of cosmetics and improve their use.
Coatings: octadecyl dimethyl amine oxide also has essential applications in coatings. It acts as an emulsifier and thickener, helping the pigment and solvent in the paint mix together to form a stable paint. At the same time, it can also improve the adhesion and water resistance of the coating so that the coating is more uniform and smooth.
Food: octadecyl dimethyl amine oxide also has a specific application in food. For example, adding an appropriate amount of octadecyl dimethylamine oxide to foods such as ice cream and milkshakes can increase the delicacy and stability of the food.

Application of Octadecyl Dimethyl Amine Oxide
Pesticides: octadecyl dimethylamine oxide also has a specific application in pesticides. It can be used as an emulsifier and dispersant of pesticides, help the active ingredients in pesticides better disperse in water, and improve the spraying and control effects of pesticides.
