You can add botanicals to the oils by infusing them before adding with water, or you can drop in a few essential oils and mix into your basic lotion once it’s cooled. – organic tea, rose water, plain water, infusionsĮxperiment with different carrier oils and emulsifiers to find the perfect balance for your ideal product. Water, Additives, and Botanicals to 100 %.Oils 12-20% – avocado, almond, olive oil.Emulsifiers 5-8% – beeswax, candelilla wax, lecithin, stearic acid, etc.As you experiment, keep in mind the basic ratios for making lotion: Now that you have a basic understanding of how and why an emulsifier works, you can start figuring out what you want to create. (Beeswax isn’t vegan, so stay away from that if you’re looking to create products for the vegan market.) We have a number of emulsifiers on our website. In cosmetics, you can use from emulsifying wax, lecitin, or stearic acid, a stabilizing agent found in vegetable fats. For cooking we often use eggs as emulsifiers. You will likely use an emulsifying wax for this emulsion.Įmulsifiers come in a variety of forms. When absorbed into the skin there is very little to no oily residue. This method creates cream and lotions that feel moist, less greasy. Oil in Water O/W – this emulsion has the oil being surrounded by water. If done correctly you will have little to no greasiness. Milk is a common example of an oil-in-water emulsion. The emulsion is often made with your choice of oil, beeswax, borax and water. Oil-in-water emulsions will mix readily with water-based liquids, while water-in-oil emulsions mix more easily with oils. 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. (ii) Water-in-oil emulsion (W/O) : The emulsion in which water forms the dispersed phase, and the oil acts as the dispersion medium is called a water-in-oil emulsion. In milk liquid fat globules are dispersed in water. 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. Milk is an example of the oil-in-water type of emulsion. 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!
