PEG-150 is a high-molecular-weight polyethylene glycol that acts as a water-soluble polymer in personal care. Formulators use it to increase viscosity, adjust texture, and aid solubilization in gels, cleansers, and hair products.
A thickener that adjusts texture for a smoother application.

Our take
Is PEG-150 a Good Ingredient?
Rated Fair: it's useful mainly as a texture builder and solubilizing aid with limited direct skin benefit, so its performance gains stay formulation-focused. Mild, concentration-dependent irritation or tackiness can also occur in sensitive users, which keeps it below Good.
What it does
Skin Benefits
Improves product body and slip for a smoother, more controlled application. Mainly improves texture and spread, offering sensorial benefits rather than direct skin effects.
Where you'll find it
Uses in Skincare & Cosmetics
Used in gel cleansers, shampoos, and hair styling gels to prevent runniness and keep formulas uniform. It also appears in lightweight lotions to fine-tune viscosity.
Before you use it
Safety
Typically low acute irritation, but higher levels may cause transient redness or stinging, particularly on sensitive skin. Suitable for rinse-off and some leave-ons when formulated appropriately; discontinue if irritation occurs. No specific cosmetic regulatory restrictions noted.
