Oil in Water O/W – this emulsion has the oil being surrounded by water. If done correctly you will have little to no greasiness. The emulsion is often made with your choice of oil, beeswax, borax and water. ![]() The level of greasiness depends on the formula – all of which will be absorbed into the skin. Water in Oil W/O – in this emulsion the oil surrounds the water and the oil touches the skin first. There are two types of emulsions: Water in Oil W/O and Oil in Water O/W. Emulsifiers work because their molecules have two parts: one part loves water and one part loves oil. One class of emulsifiers is known as “surface active agents”, or surfactants. In cosmetic chemistry– and in kitchen chemistry, we use ’emulsions’ to blend two immiscible (unblendable) liquids together.Īn emulsifier (also known as an “emulgent”) is a substance that stabilizes an emulsion by increasing its kinetic stability. Without an emulsifier, you can ‘aggitate’ the water and oil together but as soon as you stop, they fall out and separate back to oil floating on water. Since water and oil do not mix but stay separated, an additional agent (emulsifier) is necessary to form a homogenous mixture keeping water and oil together. Typically creating a lotion or cream takes three phases: a water phase, an oil phase and a finishing phase that occurs after your emulsion has cooled. Emulsifiers in action– when oil and water do mix!
