What Failed Demulsibility Results Mean
Demulsibility, or more correctly, water separation, is a measure of a lubricant’s ability to separate from water. Lubricants and water have a natural tendency to separate because most basestock molecules are non-polar, while water molecules are polar and will seek each other out instead of mixing with the base stock...
