Propyl Gallate
Ingredient Info
Propyl gallate is a synthetic antioxidant preservative used in skincare products to prevent oils and other ingredients from oxidizing and becoming rancid. It helps extend shelf life and maintain product stability over time.
Benefits
- Prevents product degradation and rancidity
- Extends shelf life of skincare formulations
- Protects other active ingredients from oxidative damage
Potential concerns
- Can cause allergic contact dermatitis in sensitive individuals; propyl gallate is the most commonly reported gallate allergen
- May trigger facial and hand dermatitis in susceptible people
- Potential for delayed allergic reactions on repeated exposure
Science: Regulatory bodies including EFSA have deemed propyl gallate safe at current exposure levels for food use, establishing an acceptable daily intake of 0.5 mg/kg body weight per day. However, 74 cases of allergic contact dermatitis linked to gallates have been documented in the literature, with propyl gallate being the most frequently reported allergen of this class in cosmetic products.
