Sodium chloride (table salt) is commonly used in cosmetics as a thickening and viscosity-control agent, particularly in surfactant-based cleansers, and also acts as a mild abrasive in scrubs. It is generally well tolerated and considered a formulation ingredient rather than a treatment active.
| Reported effect | How often | Notes |
|---|---|---|
Skin dryness or tightness | Uncommon | High concentrations may have a mild osmotic drying effect, especially on compromised skin. |
Irritation or stinging on broken skin | Uncommon | Salt can sting when applied to abrasions, cuts, or inflamed areas. |
Mechanical irritation from scrub formulations | Rare | Coarse salt particles in exfoliants may cause microabrasions if used aggressively. |
Allergic contact reaction | Very rare | True allergy to sodium chloride is exceptionally uncommon. |
