A glycol-based humectant with mild antimicrobial properties, often used as a preservative booster. The CIR affirms safety with low irritation and sensitization potential at typical concentrations (0.1–2%). Frequently paired with phenoxyethanol to reduce needed concentrations of each.

What the research flags

  • May modestly enhance skin penetration of co-formulated ingredients
  • Rare allergic reactions possible
