Peg 4 Dilaurate
PEG-4 Dilaurate is a mild, synthetic emulsifier and surfactant commonly used in UK skincare and cosmetic formulas. It helps blend oil and water-based ingredients into smooth, stable creams, lotions and cleansers while giving products a light, non-greasy feel.
How it works in skincare
In cosmetic formulations PEG-4 Dilaurate works as an emulsifying agent by reducing surface tension between oil and water phases, allowing them to mix uniformly and remain stable over time. It is frequently found in facial cleansers, body washes, moisturisers and hair conditioners where it improves texture, aids even application and helps rinse off easily without leaving residue. Its mild nature makes it suitable for a wide range of leave-on and rinse-off products.
