Sodium Chloride, commonly known as table salt, is an inorganic compound used in skincare and hair care formulations. In aqueous systems, it functions as a cost-effective thickening agent by modulating micelle structures — especially in surfactant-rich products like shampoos, body washes, and cleansers — modifying texture and viscosity. It also serves as a binding and bulking agent, aiding in the formation of cohesive products such as solid bars and scrubs, while improving product density and final structural integrity.

In haircare and scalp products, sodium chloride can act as a mild exfoliant and cleanser. In scrub formats, its crystalline form provides mechanical exfoliation, helping to remove dead skin cells. Additionally, in rinse-off treatments like saline washes, it enhances scalp clarity, potentially reducing buildup and soothing sensitivity. When properly balanced, sodium chloride supports clean performance, sensory appeal, and formulation stability.
