What it is
PPG-1-PEG-9 Lauryl Glycol Ether is a nonionic surfactant made by attaching propylene oxide and ethylene oxide units to lauryl glycol. In formulations it helps blend and stabilize oil and water phases and can act as a wetting or solubilizing aid. It is typically used at modest levels in emulsions and is appreciated for a light skin feel.
Safety & warnings
As a mild nonionic surfactant, it is generally well tolerated in leave-on and rinse-off products. Tolerability depends on use level and the overall formula.
Origin & sourcing
Synthetic. It is produced by ethoxylation and propoxylation of a lauryl alcohol-derived glycol, with the fatty portion commonly sourced from vegetable oils.
Questions everyone asks
What is this ingredient's main job?
It is a nonionic surfactant and emulsifier that helps oil and water mix and stay stable in a formula.
Does it affect the texture of sunscreen?
Yes, by emulsifying and wetting it helps create a uniform, light-feeling product, but it does not provide UV protection.
