Di-C12-15 Alkyl Adipate
INCI: DI-C12-15 ALKYL ADIPATE
A lightweight synthetic emollient that softens skin without clogging pores, ideal for oily or combination skin types.
In plain English
Di-C12-15 Alkyl Adipate is a man-made oil-like ingredient used in lotions, creams, and makeup to make them spread easily and feel silky on the skin. Unlike heavy oils, it absorbs quickly and leaves a non-greasy finish, which is why it's popular in products for oily or acne-prone skin. It's also used in sunscreens to improve texture and water resistance.

What it is
Di-C12-15 Alkyl Adipate is an ester formed from adipic acid and a blend of C12-15 alcohols. It is a clear, colorless liquid that mimics the feel of natural oils but is more stable and less likely to cause breakouts.
How it works
It sits on the skin's surface to fill in tiny gaps between skin cells, making the skin feel smoother and softer. It also helps other ingredients spread evenly and can enhance the water-resistant properties of sunscreens.
Pros
Lightweight feel
Absorbs quickly without leaving a greasy residue, making it ideal for daytime moisturizers and makeup.
Low comedogenic risk
Unlikely to clog pores, so it's a safe choice for acne-prone or oily skin types.
Cons and cautions
Synthetic origin
Derived from petrochemicals, which may not align with preferences for natural or sustainable ingredients.
Limited skin benefits beyond feel
Provides only surface-level softening and does not deliver active nutrients or antioxidants.
Best for
- People with oily or combination skin
- Those who prefer lightweight, non-greasy moisturizers
Use caution if
- Individuals seeking 100% natural or organic formulations
- Those with known sensitivity to synthetic esters (rare)
