What Is Diglyceryl Sebacate/Isopalmitate?
Diglyceryl Sebacate/Isopalmitate is an ester blend made by reacting diglycerin with two fatty acids: sebacic acid, which comes from castor oil, and isopalmitic acid, which is a branched form of the fatty acid found in palm or coconut oil. The result is a silky, oil-like ingredient that melts easily into the skin without feeling greasy.
Chemists began exploring this kind of ester in the early 2000s while looking for plant-based options that could replace heavier mineral oils. Its light texture and good skin feel quickly made it popular in modern formulations focused on a smooth finish and a clean label.
The production process starts with glycerin that is heated to form diglycerin. This is then reacted with purified sebacic and isopalmitic acids in the presence of a food-grade catalyst. After the reaction is complete, the mixture is filtered and refined until it meets cosmetic purity standards.
You will often find Diglyceryl Sebacate/Isopalmitate in moisturizers, face creams, lightweight lotions, anti-aging serums, sheet masks, sun care bases and makeup primers. Its balanced oil-to-water compatibility also makes it useful in soothing balms and aftershave products where a non-sticky finish is key.
Diglyceryl Sebacate/Isopalmitate’s Cosmetic Benefits/Uses
This ingredient pulls double duty in formulas, bringing softness and a supple feel to the skin while helping other ingredients glide on smoothly.
- Skin conditioning: Forms a breathable layer that holds moisture on the skin surface so the complexion feels hydrated and looks smoother all day
- Emollient: Fills in tiny gaps between skin cells which helps reduce roughness and gives products a silky slip during application
Who Can Use Diglyceryl Sebacate/Isopalmitate
Thanks to its light texture and breathable finish Diglyceryl Sebacate/Isopalmitate works well for most skin types including dry, normal, combination and even oily skin that dislikes heavy oils. Those with very acne prone or easily congested skin should still monitor their skin since any emollient can occasionally trap excess sebum if used in very rich formulas.
The ingredient is derived from plant based glycerin plus fatty acids sourced from castor palm or coconut oils so it is suitable for vegans and vegetarians. No animal by products are used in its production.
Current safety data shows no specific hazards for pregnant or breastfeeding women when the ingredient is used topically at typical cosmetic levels. This is not medical advice and anyone who is expecting or nursing should have their healthcare provider review their full skincare lineup to be safe.
Diglyceryl Sebacate/Isopalmitate does not make skin more sensitive to sunlight and it pairs well with both day and night routines. It is odorless non volatile and free of common allergens like gluten or nuts which broadens its compatibility for people with lifestyle or allergy concerns.

Comedogenic Rating
Rating: 1 out of 5 (low)
This ester has a branched structure and a lightweight skin feel which lets it spread easily without forming a heavy occlusive film. Lab tests show it does not significantly increase sebum retention or feed acne-related bacteria so its tendency to clog pores is minimal.
Most people prone to breakouts can use products containing Diglyceryl Sebacate/Isopalmitate without trouble, although extremely reactive or very oily skin may prefer it in lighter formulations only.
The final comedogenic profile of any product still depends on the full ingredient mix and how thickly it is applied.
Summary
Diglyceryl Sebacate/Isopalmitate acts mainly as a skin-conditioning emollient that smooths the skin surface and locks in moisture. Its balanced polarity lets it settle into the tiny spaces between skin cells, softening rough patches while leaving a velvety non-greasy finish.
Formulators like it because it combines the slip of silicone with the clean label appeal of plant-derived oils which has helped it show up in a growing number of modern moisturizers primers and sun care products. It is not yet as famous as squalane or jojoba oil but its popularity is steadily rising as brands look for light esters that feel elegant and tick the vegan box.
Safety reviews and decades of fatty-acid ester data place the ingredient in the low-risk category for topical use. It is non volatile, non sensitizing and generally well tolerated. As with any new skincare product a quick patch test is a smart way to confirm personal compatibility before applying it to a larger area.
