What it is
It is the ester of 2-ethylhexyl alcohol and palmitic acid, a clear oily liquid prized for its very light, non-greasy, dry-touch slip. Formulators use it to spread other ingredients, soften skin, and reduce the heaviness of richer oils, and it can help dissolve oil-soluble UV filters.
Safety & warnings
Generally well tolerated; like many fatty esters it has a low-to-moderate comedogenicity rating, so very acne-prone users may prefer to patch test.
Origin & sourcing
Synthetic ester, typically derived from palmitic acid (often plant-sourced, e.g. palm) and 2-ethylhexanol.
Questions everyone asks
Why is ethylhexyl palmitate in my sunscreen?
It is an emollient that makes the product spread smoothly and feel light and dry rather than greasy, and it helps dissolve oil-based UV filters.
Can it clog pores?
It is reported to have some comedogenic potential, so people very prone to breakouts may want to patch test.
