Cetearyl Alcohol

Ingredient Info

Cetearyl alcohol is a waxy, fatty alcohol derived from vegetable or petroleum sources that acts as an emulsifier and thickener in skincare products. It helps blend oil and water-based ingredients together and gives creams and lotions their smooth, spreadable texture.



Benefits

  • Stabilizes emulsions to prevent separation of oil and water
  • Thickens and improves texture of creams and lotions
  • Creates a smooth, non-greasy feel on skin

Potential concerns

  • Rare allergic contact dermatitis reported in sensitive individuals
  • May cause localized irritation or allergic reactions in patch-tested cases

Science: Cetearyl alcohol is widely used as an emulsifier in topical formulations and generally has a good safety profile. However, multiple case reports document allergic contact dermatitis in susceptible individuals, suggesting it can act as a contact allergen in rare cases. It does not significantly penetrate skin and primarily remains in the formulation.
