About this ingredient
Sodium Chloride (table salt). In cosmetics – a functional component with two roles. First – thickener for surfactant systems: adding 0.5-2% NaCl to a shampoo or shower gel with sodium laureth sulfate sharply increases viscosity (through micellar structure formation, the 'salt effect'). Second – tonicity and osmotic regulator in face physiological solutions, thermal sprays, eye products. Where applied. Shampoos, shower gels, face foams (0.2-2%), mist toners (isotonic 0.9% saline), salt scrubs (5-30% as a mild abrasive), sea-salt masks, intimate hygiene products. In Spain – in mass products and in premium 'sea salt' scrubs. Thickening effect – a narrow window. NaCl thickens only to a point: above the optimum (>3% for most systems) viscosity drops back. Formulators carefully select the concentration. Safety. CIR has not issued a standalone review (FDA GRAS status as food additive). Hypoallergenic. Well tolerated on intact skin. On damaged skin (open cuts, eczema flares) – uncomfortable stinging but no harm. Salt scrub controversy. Coarse NaCl crystals as abrasive – traumatize skin, especially on the face. Acceptable in moderation for the body; contraindicated for the face. Face alternatives – enzymatic exfoliants or chemical AHA/BHA peels. Pregnancy and lactation – safe. A natural food component, no restrictions in any product.
