What it is
Diheptyl succinate is a clear, low-viscosity diester used in skin care to provide a light, dry, non-greasy emollient feel. It is frequently paired with capryloyl glycerin/sebacic acid copolymer in moisturizing and barrier-supporting systems, where together they help form a flexible film and improve spreadability. In sunscreens it contributes to a pleasant, lightweight skin feel.
Safety & warnings
Considered a mild, well-tolerated emollient with a low irritation profile and is widely used in leave-on products including those for sensitive skin. It is not a known fragrance allergen.
Origin & sourcing
Synthetic; produced by esterifying succinic acid with heptyl (n-heptyl) alcohol.
