Compatibility
Works well with:
Glycerin Niacinamide Hyaluronic Acid Fragrance Ethanol Propylene Glycol
Dipropylene Glycol is broadly compatible with most cosmetic ingredients and is frequently used as a co-solvent to aid in dissolving fragrances, actives, and other raw materials. It is miscible with water and many polar organic solvents, making it highly versatile across formulation types. No significant incompatibilities are commonly reported at typical use levels.
Formulation notes
Dipropylene Glycol is a colorless, low-odor diol used primarily as a solvent, co-solvent, and humectant in cosmetic and personal care formulations including lotions, serums, toners, and fragrance products. It helps solubilize fragrance compounds and improves skin feel, contributing mild moisture-retention properties. It is considered well-tolerated with a low sensitization potential, though high concentrations may cause mild irritation in sensitive individuals.
