Emulsion vs. Latex: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on October 16, 2023
An emulsion is a mixture of two unblendable substances, often oil and water, while latex is a natural or synthetic dispersion of polymer particles in water.
Key Differences
An emulsion pertains to the dispersion of one liquid in another immiscible liquid, commonly oil in water or vice versa. On the other hand, latex refers to a dispersion of polymer particles, either natural or synthetic, in water.
Emulsions find their place in various fields, from culinary arts where salad dressings like vinaigrettes are prepared, to cosmetics and pharmaceuticals. Latex, in contrast, is extensively used in the manufacture of rubber products, paints, and certain adhesives.
Emulsions typically require stabilizing agents, or emulsifiers, to prevent the separated phases from coalescing. Meanwhile, latex preparations often incorporate stabilizers to preserve the dispersion and prevent the particles from agglomerating.
Emulsions can vary in their appearance, ranging from milky to opaque, based on the droplet size and concentration of dispersed phase. Latex, in general, appears milky because of its dispersed polymer particles in water.
Emulsions are essentially combinations of immiscible liquids stabilized by emulsifiers. Latex can be of natural origin, like the sap from rubber trees, or synthetic, formulated from specific polymer dispersions.C

Latex
Dispersion of polymer particles in water.
The paint contained acrylic latex for durability.
Emulsion
Varies in consistency based on droplet size.
The emulsion appeared milky due to its fine droplets.
Latex
Natural sap of certain plants.
Rubber is derived from the latex of rubber trees.
Emulsion
Mixture of two unblendable liquids.
Mayonnaise is an emulsion of oil and vinegar.
Latex
Used in making rubber products.
The gloves were made of natural latex.
Emulsion
A liquid dispersed in another immiscible liquid.
The chef made an emulsion of lemon juice and olive oil.
Latex
Can be natural or synthetic.
The mattress had layers of synthetic latex.
Emulsion
A suspension of small globules of one liquid in a second liquid with which the first will not mix
An emulsion of oil in vinegar.
Latex
Often appears milky in consistency.
The latex paint had a smooth, milky texture.
Emulsion
A photosensitive coating, usually of silver halide grains in a thin gelatin layer, on photographic film, paper, or glass.
Latex
The colorless or milky sap of certain plants, such as the poinsettia or milkweed, that coagulates on exposure to air.
Emulsion
A stable suspension of small droplets of one liquid in another with which it is immiscible.
Mayonnaise is an emulsion where egg is used to keep oil and water mixed.
Latex
A polymer emulsion consisting of such sap obtained from rubber trees, used to manufacture various thin elastic products such as balloons, disposable gloves, and medical and contraceptive devices. Some people are allergic to this substance. Also called natural rubber latex.
Emulsion
(chemistry) A colloid in which both phases are liquid.
Latex
A similar material made from polymers derived from petroleum; synthetic latex.
Emulsion
(photography) The coating of photosensitive silver halide grains in a thin gelatine layer on a photographic film.
Latex
Latex paint.
Emulsion
Any liquid preparation of a color and consistency resembling milk; as: (a) In pharmacy, an extract of seeds, or a mixture of oil and water united by a mucilaginous substance. (b) In photography, a liquid preparation of collodion holding salt of silver, used in the photographic process.
Latex
A clear liquid believed to be a component of a humour or other bodily fluid esp. plasma and lymph

Latex
(uncountable) Natural latex rubber, especially non-vulcanized rubber, such as is used in making latex gloves, latex condoms, and latex clothing.
Latex
A milky or colored juice in certain plants in cavities (called latex cells or latex tubes). It contains the peculiar principles of the plants, whether aromatic, bitter, or acid, and in many instances yields caoutchouc upon coagulation. The lattex of the India rubber plant produces the rubber of commerce on coagulation.
