Diethylhexyl Succinate
What is Diethylhexyl Succinate?
Diethylhexyl Succinate is a synthetic emollient and solvent derived from succinic acid and 2-ethylhexanol, commonly used in skincare and cosmetic formulations to provide a non-greasy, lightweight feel. It functions as a texture enhancer, helping to solubilize other ingredients and improve product spreadability while imparting emolliency without heaviness. This ingredient is particularly valued in oil-free and mattifying products due to its dry-touch sensory profile.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Solvent
Dissolves and carries other ingredients, helping control viscosity, evaporation rate, and delivery of actives in both water- and oil-based systems.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
