Hexylene Glycol

7.8

Ingredient Info

Hexylene glycol is a lightweight humectant and preservative booster used in skincare products to help retain moisture and improve product stability. It also enhances the penetration of other active ingredients into the skin.



Benefits

  • Helps skin retain moisture
  • Improves product texture and spreadability
  • Enhances effectiveness of preservative systems

Potential concerns

  • May cause mild irritation or redness in sensitive individuals (occurs in roughly 3% of eczema-prone skin)
  • Potential for delayed allergic contact reactions in susceptible people, though this is uncommon
  • Less irritating than propylene glycol under occlusion, but still worth avoiding if you have known sensitivities to glycols

Science: A 1989 study found hexylene glycol caused visible skin reactions in 2.8% of eczema patients at high concentrations (30-50%), with potential for delayed allergic sensitization in rare cases. It was less irritating than propylene glycol. One case report mentions hexylene glycol as a potential allergen in medical formulations, though reactions are uncommon at typical cosmetic concentrations.
