Worth knowing

  • Fragrance allergens listed: Linalool, Citronellol. In the EU these must be named when above 0.001% in leave-on or 0.01% in rinse-off products.
  • Alcohol Denat. is high on the list (#4). It can feel drying or stinging on dry or sensitive skin.
  • Alcohol appears at #33, lower down the list, so the amount is likely small.
