Latex refers generically to a stable dispersion (emulsion) of polymer microparticles in an aqueous medium. Latexes may be natural or synthetic. Latex as found in nature is the milky sap of many plants that coagulates on exposure to air. It is a complex emulsion in which proteins, alkaloids, starches, sugars, oils, tannins, resins and gums are found. In most plants, latex is white, but some have yellow, orange, or scarlet latex.
The word is also used to refer to natural latex rubber; particularly for non-vulcanized rubber. Such is the case in products like latex condoms and latex clothing. It can also be made synthetically by polymerizing a monomer that has been emulsified with surfactants.
