Sodium Chloride
What is Sodium Chloride?
Sodium Chloride is an inorganic ionic compound, known as table salt, sourced from evaporated seawater or mined rock deposits. In cosmetics, it falls under inorganic salts used in skincare, haircare, cleansers, and primarily oral care formulations like toothpastes and mouthwashes. Chemically simple with sodium cations and chloride anions, it functions mainly by altering solution properties. It increases viscosity through interactions with thickeners like cellulose derivatives, promoting product stability, smooth texture, and even dispensing. In oral products, it aids cleaning by gentle abrasion and osmotic effects that disrupt microbial balance. Its hygroscopic nature helps control moisture, while solubility allows easy incorporation. Valued for multifunctionality, it enhances overall formula performance without adding complexity or color.
