I assume you mean during an extraction or wash in a sep funnel. It depends on many factors: 1) Choice of solvent. Dichloromethane is very prone to forming emulsions, while it is almost impossible to form one with ethyl acetate. 2) Shaking violently tends to form emulsions. For this reason use a gentle rocking motion to mix the two layers. 3) If an emulsion does form, adding a small amount of brine can often break up the emulsion. 4) If an emulsion forms and you can't get rid of it, you can just wait it out (but sometimes it takes an entire night... not a big deal if your purification is not pressing).

What mixtures are in emulision?
An emulsion is a mixture of two or more immiscible substances, usually a liquid dispersed in another liquid. Common examples include oil and water, where one substance is dispersed as small droplets in the other. Emulsions are stabilized by emulsifiers to prevent the droplets from coalescing.
Does emulsion settle out on standing yes or no?
Yes, emulsions can settle out on standing. Over time, the dispersed droplets in an emulsion may coalesce and separate from the continuous phase, leading to a separation of layers. The stability of an emulsion depends on factors like the type of emulsifier used and the emulsion's formulation. If not stabilized properly, emulsions are prone to breaking or settling.
What type of colloid does a shampoo?
Shampoo is a type of colloid known as an emulsion. Emulsions are a mixture of two immiscible liquids, in this case water and oils, stabilized by an emulsifying agent. This allows the shampoo to effectively clean the hair by mixing with both oil and water-based dirt and residues.
Can Suspensions may also be called emulsions?
No, suspensions and emulsions are different types of mixtures. Suspensions are mixtures in which solid particles are dispersed in a liquid, while emulsions are mixtures of two or more liquids that are immiscible.
Who invented emulsion?
Emulsions have been used for centuries, but the process of creating stable emulsions was popularized by French chemist Jean-Baptiste Dumas in the 19th century. He is often credited with laying the foundation for our understanding of emulsions.

What types of emultion is there?
There are water-in-oil emulsions, oil-in-water emulsions, and multiple emulsions (water-in-oil-in-water or oil-in-water-in-oil).These emulsions are used in various industries including food, cosmetics, and pharmaceuticals.
What is xray film emulsions sensitive to?
X Ray film emulsions are sensitive to light.
What are the differences between oil in water and water in oil emulsions?
Oil in water emulsions have oil droplets dispersed in water, while water in oil emulsions have water droplets dispersed in oil. The main difference lies in the continuous phase, with oil being the continuous phase in oil in water emulsions and water being the continuous phase in water in oil emulsions. This affects the stability, appearance, and properties of the emulsions.

What are the differences between emulsion and extract in terms of their composition and uses?
Emulsions are mixtures of two or more liquids that are usually immiscible, like oil and water, stabilized by an emulsifying agent. Extracts are concentrated solutions obtained by extracting the desired components from a substance, like herbs or plants, using a solvent. Emulsions are used in food products, cosmetics, and pharmaceuticals for their stability and texture, while extracts are commonly used in cooking, medicine, and skincare for their concentrated flavors or active ingredients.
