Question

What do you understand by o/w type emulsions? Give one example.

Answer 1

Oil-in-water (o/w) emulsions are colloidal dispersions where oil droplets are dispersed in water, which acts as the dispersion medium. They are stabilized by emulsifying agents like soaps. A common example is milk, where fat droplets are dispersed in water. O/w emulsions show typical colloidal properties and are important in many food and pharmaceutical products.
