What it is
Polyglyceryl-6 Oleate is an ester of polyglycerin (six glycerin units) with oleic acid. It is a non-ionic, PEG-free emulsifier that helps disperse oils in water and stabilize emulsions, and it can also act as a mild surfactant and skin-conditioning agent. Its liquid, oil-compatible nature makes it useful in lightweight lotions and water-based sunscreens.
Safety & warnings
Polyglyceryl oleate esters are generally well tolerated and are valued in gentle, PEG-free formulas for their mild, non-ionic character. They have low sensitizing potential. Because the oleate (oleic acid) portion is a fatty component, very acne-prone users may prefer to observe how oil-rich formulas containing it suit them.
Origin & sourcing
Synthetic ester typically derived from plant-sourced glycerin and oleic acid (a fatty acid).
Questions everyone asks
What role does Polyglyceryl-6 Oleate play in a formula?
It is a mild, non-ionic emulsifier and surfactant that helps blend oils into water and stabilize the emulsion, while also conditioning the skin.
Is Polyglyceryl-6 Oleate suitable for sensitive skin?
It is generally considered gentle and is often chosen for PEG-free, sensitive-skin formulas, though individual tolerance always varies.
