Oleth-5
This nonionic surfactant is produced by ethoxylating oleyl alcohol to an average of five EO units, used in cleansing and emulsifying systems to solubilize oils, boost foam with co-surfactants, and support uniform texture.

Our take
Is Oleth-5 a Good Ingredient?
Rated Fair: it's a useful nonionic surfactant for cleansing and solubilization, but it can irritate sensitive skin and is harsher than many of the milder surfactants now available, which limits its score.
What it does
Skin Benefits
Improves cleansing efficacy and helps create a rich, cushiony lather for a freshly washed feel. Helps skin feel clean without heaviness.
Where you'll find it
Uses in Skincare & Cosmetics
Frequently used in face washes, body washes, and shampoos to support a creamy foam profile. Also incorporated into light emulsions and cleansing lotions to disperse oily residues.
Before you use it
Safety
Can trigger dryness or irritation, particularly with frequent use or on delicate areas; keep concentrations modest and rinse well. Manufacturing standards aim to limit residual ethoxylation by-products, but cautious users may prefer gentler alternatives.
