Common Name(s): Glyceryl isotridecanoate/stearate/adipate,mixed glyceryl ester blend,glycerol mixed ester
DESCRIPTION
What It Does: Softens skin and helps oil and water blend in formulas with a non-greasy finish.
Why It's Used: A mixed-ester approach combining branched (isotridecanoate), straight-chain (stearate), and diacid (adipate) components to create a versatile emollient-emulsifier with a tunable skin feel.
How It Works: Mixed ester profile lowers crystallinity versus single-acid glyceryl esters; adipate diester contributes emulsification character; isotridecanoate branching reduces greasiness.
Typically Found In: Facial moisturizers,multi-function emollients,balanced texture formulas

Source Notes: Glycerin plant-derived; fatty acids from synthetic/plant sources; semi-synthetic mixed ester. [audit 2026-07-29 rev2: origin-dependent: the same inci exists in plant, animal and petrochemical versions and the name does not discriminate. determination requires shariah-panel sign-off.]
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – low
Sensitivity Concerns: Generally well tolerated.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile. ewg score: 1.
Works Well With: Fatty alcohols,emollients,natural oils
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Mixed glyceryl esters of diverse fatty acids represent an advanced emollient design strategy where the combination of fatty acid chain types (branched/linear/diacid) provides a customized melting profile and skin feel not achievable with single-acid esters.
