What types of products are made with water in oil emulsions?
These emulsions are utilized in products including butter, margarine, cold cream and cod liver oil and are especially useful in products designed for dry or sensitive skin. Common w/o emulsifiers are sorbitan stearate, polyglyceryl oleate, lecithin, sorbitan monooleate and lanolin.
What foods use the emulsion process?

Is cream a water in oil emulsion?
A cream is basically a mixture of oil and water. As you know oil does not readily dissolve or disperse in water, so to allow this to happen, a dispersing agent called an emulsifier is added to the mixture. A cream is therefore a type of emulsion, made of a water phase and an oil phase.
