Potassium Behenate

What is Potassium Behenate?

Potassium Behenate is the potassium salt derived from behenic acid, a saturated fatty acid containing 22 carbon atoms, commonly obtained from vegetable sources like rapeseed or peanut oils. This soap-like compound forms through the reaction of behenic acid with potassium hydroxide. Primarily featured in cleansing cosmetics such as bar soaps, liquid washes, shampoos, and facial cleansers, it acts as a surfactant by decreasing water's surface tension. This property allows it to blend with skin oils and debris, creating micelles that trap and remove impurities during rinsing. Its long-chain structure contributes to mild action, helping maintain skin's natural moisture barrier while enabling effective foaming and emulsification in formulations.

Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Cleansing agent
Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.

Benefits

Delivers soft cleansing by emulsifying oils and dirt for easy removal.

Supports foam formation in shampoos and body washes.

Non-comedogenic profile suits pore-friendly routines.
