Sodium Carbonate
Ingredient Info
Sodium carbonate is an alkaline salt commonly used in skincare products as a pH buffer and exfoliating agent. It helps balance acidity in formulations and can gently remove dead skin cells from the surface of the skin.
Benefits
- Gentle chemical exfoliation to remove dead skin cells
- pH balancing in skincare formulations
- May help soften and condition the skin
Potential concerns
- Can cause irritation, dryness, or redness if used at high concentrations or on sensitive skin
- May disrupt the skin's natural pH barrier if overused
- Strong alkalinity could cause burning or stinging sensations
Science: Research shows sodium carbonate effectively degrades pectin structures and alters skin composition in food applications, suggesting similar exfoliating effects on human skin. However, limited peer-reviewed safety data exists specifically for cosmetic use on facial or body skin at typical product concentrations.
