In cosmetics, an emulsifier includes any ingredient that helps keep unlike ingredients (such as oil and water) from separating in an emulsion. They are widely used throughout the cosmetics industry and are the unsung heroes of many cosmetics formulas that blend and help to keep unlike ingredients together.

Emulsifiers are used in creams and lotions to mix water with oils. 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. There are 2 types of emulsifiers. Oil-in-water (o/w) emulsifiers keep oil drops packed in water, while water-in-oil (w/o) emulsifiers keep water drops packed in oil. W/O emulsifiers are used for a fatty feel (e.g night & sun protection creams). O/W emulsifiers are used more in moisturizing products (e.g. body lotions, day creams).

One of the best emulsifier available in market is Kumar Organic?s Kopester PGO. The chemical name of Kopester PGO is Polyglycerol-4 Oleate. Polyglyceryl-4 Oleate is an ester of oleic acid and polyglycerin-4. It is the combination of Glycerine and Oleic acid. Glycerine is naturally water-loving (the structure of the molecules make it like a magnet to water molecules) and fatty acids like oleic acid are naturally oil-loving. When you combine these qualities into one compound, you have the perfect ingredient for helping keep all of the other ingredients in a formula together! In technical terms, it?s called an ?emulsifier? and if you want to visualize it at work, think of what it looks like when you mix oil and water ? they quickly go their separate ways (the oil floats up and the water sinks down). If you added an emulsifier and mixed it all up, all three ingredients would remain evenly dispersed as one, uniform final product. It helps create a stable mixture for a consistent, refreshing experience every time.

Other than as emulsifier Kopester PGO is used as Additives, thickner and moisturizer. Polyglycerol oleate make skin feel fantastic, thanks to their marked substantivity. They do not irritate the skin, as they do not cause any denaturing of the skin?s proteins. Depending on the type, they have a non-roughening to smoothing effect on the skin and regulate humidity.

This plant-based, mild emulsifier is an excellent alternative to the more questionable standard alternatives like polyethylene glycol (PEG) and triethanolamine (TEA).
