Chemistry & ProductsQuestion 315 of 484
Most lotions, conditioners, and creamy hair colors are oil-in-water (O/W) emulsions, meaning:
a.Water droplets are suspended inside a continuous oil phase
b.There is no water present; only oils and waxes
c.Oil and water form two separate layers that are shaken together at use
d.Oil droplets are dispersed throughout a continuous water phase
Explanation
In an oil-in-water emulsion, tiny oil droplets are suspended in a much larger continuous water phase, stabilized by an emulsifier. O/W products feel lighter and less greasy, which is why they dominate lotions and rinse-out conditioners. W/O is the reverse (water-in-oil) and feels heavier.
