Colloid vs. Emulsion

Colloidadjective

Glue-like; gelatinous.

Colloidnoun

(chemistry) A stable system of two phases, one of which is dispersed in the other in the form of very small droplets or particles.

Colloidnoun

(meteorology) An intimate mixture of two substances one of which, called the dispersed phase (or colloid), is uniformly distributed in a finely divided state throughout the second substance, called the dispersion medium (or dispersing medium).

Colloidnoun

(geology) A particle less than 1 micron in diameter, following the Wentworth scale

Colloidadjective

Colloidnoun

A substance (as albumin, gum, gelatin, etc.) which is of a gelatinous rather than a crystalline nature, and which diffuses itself through animal membranes or vegetable parchment more slowly than crystalloids do; - opposed to crystalloid.

Colloidnoun

Colloidnoun

a mixture with properties between those of a solution and fine suspension

Colloid

A colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance. However, some definitions specify that the particles must be dispersed in a liquid, and others extend the definition to include substances like aerosols and gels.

Emulsionnoun

A stable suspension of small droplets of one liquid in another with which it is immiscible.

Emulsionnoun

(chemistry) A colloid in which both phases are liquid.

Emulsionnoun

(photography) The coating of photosensitive silver halide grains in a thin gelatine layer on a photographic film.

Emulsionnoun

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.

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.
