Merriam-Webster Dictionary

Definition of soluble oil
1: sulfonated oil
2: an emulsifiable oil (such as a mineral oil containing a sulfonated oil or a soap as emulsifier) for use in the form of an aqueous emulsion as a cutting fluid, textile lubricant, or carrier for insecticides; also : the emulsion formed from such an oil

Surely an emulsion and a solution ar to difrent things?
