Yes. It's called and emulsion. They can be forced together by whisking, but will separate, or mixed through the use of an emulsifier, in vinaigrettes, most commonly a mustard like dijon.

it usually is a mixture of oil and vinegar.
Oil and vinegar dressing is a suspension because it consists of two immiscible liquids (oil and vinegar) that do not dissolve into each other. The vinegar forms droplets that are dispersed throughout the oil, creating a cloudy appearance.
Suspension
It is just a mixture. However, the salad dressing may be a suspension. For instance, Italian dressing is made using oil and vinegar which of course does not mix well.
suspension
yes because salad dressing is a suspension of vinegar that will separate into layers if left undisturbed.
Salad dressing contains some kind of oil mixed with vinegar, and these two substances are immiscible; they do not dissolve in each other, although if you mix them together you can get a suspension (which is temporary).
Oil has a lower density compared to vinegar. Oil floats on top of vinegar because it is less dense.
This could be a suspension mixture where one component is insoluble in the solvent and settles due to gravity. This separation process is known as sedimentation. Examples include sand and water, or oil and vinegar.
Italian dressing is considered a suspension because it contains various ingredients, such as oil, vinegar, herbs, and spices, that do not fully dissolve or blend together. In a suspension, the solid particles remain mixed in the liquid but can settle over time, requiring shaking before use. This characteristic is evident in Italian dressing, as the oil and vinegar separate when left standing, necessitating mixing for an even distribution of flavors.
