What It Does
PEG-7 Lauryl Ether is a nonionic ethoxylated surfactant created by reacting lauryl alcohol (typically derived from coconut or palm kernel oil) with approximately 7 moles of ethylene oxide. This specific degree of ethoxylation gives it a balanced HLB value around 12-13, making it particularly effective as both a mild cleansing agent and an oil-in-water emulsifier. Formulators favor it for its ability to solubilize fragrances and essential oils in aqueous systems, its mildness compared to anionic surfactants, and its compatibility with a wide range of cosmetic ingredients, making it especially useful in facial cleansers, micellar waters, and light emulsions.

Ingredient Compatibility
Known Interactions
Ethoxylated surfactants (Ceteareth-*, PEG-*, Polysorbate-*, Poloxamer-*) accumulate peroxides over shelf life via air oxidation of the polyoxyethylene chain. The resulting peroxides degrade DHA, accelerating off-smell and producing orange tones. For DHA formulations, prefer non-ethoxylated emulsifiers: Polyglyceryl-* esters (Polyglyceryl-6 Distearate, Polyglyceryl-10 Stearate), Lecithin, Sucrose Stearate, Olivem 1000 (Cetearyl Olivate + Sorbitan Olivate).
