Benzyl Alcohol

At typical cosmetic concentrations (up to 1%) benzyl alcohol is generally well tolerated. However, it is listed under EU CosIng Annex III (entry 45, restricted to 1% in finished products) and Annex V (entry 34, as a preservative up to 1%). It is also one of the 26 EU-regulated fragrance allergens and must be declared on labels above 0.001% in leave-on products or 0.01% in rinse-off products. In high concentrations it can cause irritation and contact dermatitis.

Benzyl alcohol is generally considered safe at typical cosmetic concentrations (up to 1%) during pregnancy. However, concentrated or pharmaceutical-grade benzyl alcohol has been associated with toxicity in neonates ('gasping syndrome') when administered intravenously. Normal topical cosmetic use at regulated concentrations is not expected to pose risk, but some practitioners recommend caution.
