Demulsifier is a chemical used to break emulsions that is, to separate the two phases. The type of demulsifier selected depends on the type of emulsion, either oil-in-water or water-in-oil.
ml (milliliter) is a unit of volume, ppm (parts per million) is a unit for concentration. You can't directly convert one to the other. You will need additional information; for example, how much of the substance you have, and how much of the other substance.
There is an organic chemical group called "proxamine", a demulsifier. "Proximian Mythos" is a 1995 mythical reference by the techno music group "Cybotron".
An additive called a demulsifier is used in lubricating oil to help separate and remove water from the oil. Demulsifiers work by breaking down the emulsions that form between the water and the oil, allowing the water to separate out more easily.
