Sodium Palmitate
Sodium Palmitate is the sodium salt of palmitic acid, a saturated fatty acid. It is commonly found in bar soaps and cleansing bars, where it functions as a surfactant and cleansing agent. It also contributes to emulsification and helps control the viscosity or texture of formulations. Its CAS number is 408-35-5 and EC number is 206-988-1.
Sodium Palmitate primarily provides cleansing by helping to remove dirt and oils from the skin. It also acts as an emulsifier to stabilize formulations and contributes to the firmness and lather of bar soap products.
As a soap-derived surfactant, it may be drying or irritating for sensitive or dry skin types with frequent use. It can also raise skin surface pH, which may disrupt the skin's natural acid mantle.
