What Is Potassium Hydrogenated Palmate?

Potassium Hydrogenated Palmate is the potassium salt that forms when hydrogenated palm fatty acids react with a mild alkali. In simple terms it comes from palm oil, a vegetable oil harvested from the fruit of oil palm trees. First the palm oil is hydrogenated, a process that adds hydrogen to the fatty acids so they become more stable and solid at room temperature. These hardened fatty acids are then combined with potassium hydroxide to create a soap-forming salt: Potassium Hydrogenated Palmate.

Soapmakers have relied on palm-based salts for well over a century because they give a firm texture and a creamy lather. As formulators moved from traditional bar soap to modern liquid and foaming cleansers this ingredient stayed popular since it dissolves easily in water and rinses clean.

Today you will most often see Potassium Hydrogenated Palmate in facial cleansers, body washes, hand soaps, foaming shave creams and some solid cleansing bars. Its plant origin, reliable performance and gentle feel on skin have made it a staple for both mass-market and natural-positioned brands.
