Decyl Glucoside

Decyl Glucoside

7.0

Ingredient Info

Decyl glucoside is a mild, plant-derived surfactant made from natural fatty alcohols and glucose. It's used in skincare products to cleanse the skin and help other ingredients mix together, and is generally gentler than many traditional detergents.



Benefits

  • Mild cleansing action suitable for sensitive skin
  • Plant-based and renewable ingredient
  • Functions as an effective emulsifier to stabilize formulas

Potential concerns

  • Can cause allergic contact dermatitis in sensitive individuals—cases of sensitization have increased since the early 2000s
  • May cross-react with other similar glucoside ingredients
  • Can be irritating if formulation is not properly balanced

Science: The Cosmetic Ingredient Review panel concluded decyl glucoside is safe when used in non-irritating formulations at current concentrations. However, dermatology literature documents a steady rise in allergic contact dermatitis cases, particularly when it appears as a 'hidden' ingredient in sunscreens like Tinosorb M, making patch testing advisable for those with suspected sensitivities.
