TRIETHYLENE GLYCOL
Is TRIETHYLENE GLYCOL safe for seborrheic dermatitis?
Triethylene Glycol is generally a lower-concern formula ingredient for seborrheic dermatitis. It works mainly as a solvent, carrier or viscosity aid and is not a treatment.
It is not a fatty oil and no ingredient-specific Malassezia concern was found. Its effect depends on how much is used and what it carries in the formula, including fragrance. The complete product can still irritate inflamed skin, so a simple fragrance-free option may be easier to assess during an active flare.

What is TRIETHYLENE GLYCOL used for in skincare?
Triethylene Glycol is a small water-compatible glycol used to dissolve ingredients, carry fragrance and adjust the flow or viscosity of a formula. It can help distribute other components evenly and support a consistent texture. It is typically present as a supporting solvent alongside water, humectants, preservatives or fragrance materials.
