What it is
Olive Oil PEG-7 Esters is made by reacting olive oil with polyethylene glycol, producing a water-dispersible material that combines emollient character with surfactant properties. It helps blend oil and water phases, can solubilize lipophilic ingredients, and leaves a soft skin feel. In sunscreens it is used to support texture and the even distribution of the oil phase.
Safety & warnings
PEG-modified olive oil esters are generally well tolerated and milder than many ionic surfactants. As an ethoxylated material, manufacturing controls aim to limit trace impurities. It is not considered notably comedogenic, though heavy emollient esters can feel rich on very oily skin.
Origin & sourcing
Semi-synthetic. It is derived from natural olive oil that has been chemically modified through ethoxylation with polyethylene glycol.
Questions everyone asks
Is Olive Oil PEG-7 Esters natural?
It starts from natural olive oil but is chemically modified with polyethylene glycol, making it a semi-synthetic ingredient rather than a pure plant oil.
What is its role in sunscreen?
It works as an emollient and emulsifier, helping combine oil and water phases and contributing to a smooth, spreadable texture.
