Dipropylene Glycol

Dipropylene Glycol

8.2

Ingredient Info

Dipropylene glycol is a lightweight humectant and solvent derived from propylene glycol that helps skincare products absorb into skin while drawing moisture to the surface. It's commonly used in serums, toners, and lightweight moisturizers to improve texture and hydration.



Benefits

  • Humectant that draws moisture into the skin
  • Lightweight feel that doesn't leave greasy residue
  • Enhances absorption of other active ingredients
  • Helps preserve product stability

Potential concerns

  • Rare potential for allergic contact dermatitis in sensitive individuals (documented in medical device contexts)
  • May cause irritation or sensitization in people with compromised skin barriers
  • Unlikely concern in typical skincare concentrations, but those with known propylene glycol sensitivity should avoid

Science: Dipropylene glycol diacrylate (a related compound) has been identified as an allergen in medical devices in patch testing studies, though the base dipropylene glycol ingredient itself has limited published dermatology data. Allergic reactions appear rare and primarily documented in specialized medical contexts rather than cosmetic skincare use.
