What it is
Caprylic/Capric/Succinic Triglyceride is an ester made from glycerin combined with caprylic, capric, and succinic acids, related to the familiar caprylic/capric triglyceride but with added succinic acid for a distinct, dry sensory. It functions as a light, quickly absorbing emollient that softens skin and helps dissolve and evenly disperse oil-soluble UV filters and other actives. It is valued in sunscreens for giving a smooth, non-tacky feel and improving spreadability.
Safety & warnings
Triglyceride esters of this class are generally well tolerated, mild, and considered low in irritation and sensitization potential. It is usually regarded as a light, low-comedogenicity emollient, though individual responses vary.
Origin & sourcing
Synthetic ester typically derived from plant-based fatty acids and glycerin combined with succinic acid.
Questions everyone asks
How is this different from caprylic/capric triglyceride?
It is a similar lightweight ester but also includes succinic acid, which gives a drier, lighter skin feel while serving the same emollient and solvent roles.
Why use it in sunscreen?
It dissolves oil-soluble UV filters and spreads them evenly while leaving a light, non-greasy finish, improving the product's texture.
