Can I use PEG-180 with Sodium Lauryl Sulfate?
Works well together
PEG-180 and Sodium Lauryl Sulfate are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
Sodium Lauryl SulfateSurfactant
- ✓Highly effective anionic surfactant that removes oil, dirt, and makeup — the gold-standard cleansing agent in rinse-off products
- ✓Creates abundant foam, which many users associate with thorough cleansing in facial washes and powder washes
- ⚠Potent skin irritant at typical use concentrations in leave-on products; disrupts the skin barrier by solubilizing intercellular lipids
- ⚠Can trigger flares in eczema, rosacea, and sensitive skin — many dermatologists recommend SLS-free cleansers for these conditions
- ⚠Not appropriate for leave-on formulations at any practical concentration; concerns are less significant in very brief-contact rinse-off products
