The application scope of food grade white mineral oil in China is smaller than that of other white mineral oils. However, with the continuous improvement of domestic industry requirements, relevant product regulations and national food laws and regulations, the use of food grade white mineral oil is showing a growing trend. Food grade white oil can be divided into many types according to viscosity.
