Potassium Laurate
Potassium Laurate is the potassium salt of lauric acid, producing a high-foaming, water-soluble soap surfactant. Hand washes and shaving products use it for quick lather, effective soil removal, and oil dispersion in alkaline systems.

Our take
Is Potassium Laurate a Good Ingredient?
It rates Fair: it delivers strong, fast-foaming cleansing, but the support is mainly functional rather than clinical and relies on high-pH soap systems, which can be stripping or irritating for dry or sensitive skin at higher levels.
What it does
Skin Benefits
Generates rich foam and removes greasy residue efficiently; may be too strong for very dry skin. Clinical backing is limited; benefits reflect cleansing performance in soap systems.
Where you'll find it
Uses in Skincare & Cosmetics
Common in hand cleansers, shaving foams, and body washes to maximize foam volume and cleansing strength in high-pH wash bases.
Before you use it
Safety
Safe for typical rinse-off use, yet its high-pH soap character may disrupt the skin barrier, causing tightness or irritation in some users. Limit contact time if skin is dry or reactive and avoid eye exposure.
