Sodium Dehydroacetate
Ingredient Info
Sodium dehydroacetate is a synthetic preservative used in skincare products to prevent bacterial and fungal growth, extending shelf life. It's a salt form of dehydroacetic acid and is widely used across cosmetics, foods, and personal care items.
Benefits
- Prevents microbial contamination and product spoilage
- Extends product shelf life without refrigeration
- Allows formulations to remain stable over time
Potential concerns
- May cause allergic contact dermatitis in sensitive individuals
- Limited data on long-term skin effects in humans at cosmetic concentrations
Science: The Cosmetic Ingredient Review Panel has deemed sodium dehydroacetate safe as used in cosmetics (most recent affirmation in 2024). However, animal studies show it can affect cellular respiration at high concentrations; human skincare studies at approved usage levels are limited. Rare cases of allergic contact dermatitis have been documented.
