Also known as
Diglycerol Diglycérine Bis(glycerol) Glycerol dimer
Compatibility
Works well with:
Glycerin Hyaluronic Acid Niacinamide Panthenol Betaine Sodium PCA
Diglycerin is broadly compatible with most cosmetic ingredients and co-humectants. It can be used alongside glycerin and other polyols to build layered moisture-retention systems. No significant known incompatibilities at typical use levels.
Formulation notes
Diglycerin is a dimer of glycerin with superior moisture-binding capacity compared to glycerin itself, making it a high-performance humectant in skin and hair care. It is well-tolerated and provides a less sticky skin feel than glycerin at equivalent concentrations. Formulators often use it in leave-on treatments, serums, and moisturizers where a lightweight, deeply hydrating effect is desired.
