Sodium palmate is the sodium salt of palmitic acid (from palm oil), produced by saponification and used as a primary base ingredient in bar soaps. It functions as a surfactant and cleanser, providing lather and structure to solid soap products.
| Reported effect | How often | Notes |
|---|---|---|
Skin dryness and tightness | Common | Alkaline soap-based surfactants can strip natural oils and disrupt the skin barrier with frequent use. |
Irritation or stinging | Uncommon | More likely on sensitive, compromised, or eczema-prone skin due to elevated pH. |
Allergic contact dermatitis | Rare | True allergy to the fatty acid salt is uncommon; reactions are more often attributed to added fragrances or other soap components. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
