Key Differences
An emulsion is a mixture where tiny droplets of one liquid are dispersed within another, such as oil in water. Latex, on the other hand, specifically refers to a colloidal dispersion of polymer particles in a liquid. Emulsions are characterized by their instability and can separate over time, whereas latex is usually a stable product and does not easily separate.
The creation of an emulsion typically requires mechanical action, like stirring or shaking, to disperse the liquid droplets. In contrast, latex is formed through polymerization processes that create the polymer microparticles which are then dispersed in water or another liquid. Emulsions can be found in many products including food, cosmetics, and pharmaceuticals. Latex is used in products like gloves, balloons, and paints due to its elastic properties.
Emulsions are used in various industries because they can improve the texture, taste, and shelf-life of products. Latex serves a different function; it is often used in manufacturing and medical industries for its protective properties. The components of an emulsion are usually two immiscible liquids like oil and water. Latex involves one component as a dispersed solid in liquid form, usually synthetic or natural rubber in water.
The stability of an emulsion can often be enhanced with emulsifiers, which are substances that stabilize the mixture. Latex does not typically require stabilizers because the polymer particles are naturally stable in the liquid. Emulsions require careful formulation to prevent separation of their components. Latex, when created, is inherently stable and thus is commonly used for its durability.

Emulsion
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids.
Latex
Latex materials are known for their elasticity.
The balloon artist used latex balloons for their flexibility and strength.
Emulsion

Latex
Latex is a stable dispersion (emulsion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well.
Emulsion
