What it is
A synthetic ester made from adipic acid and fatty alcohols derived from plants (often coconut or palm). It is a clear, odorless liquid that mimics the texture of natural oils but is lighter and more spreadable.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smooth, even feel. It also helps other ingredients spread more easily and reduces water loss by forming a thin, breathable film.
Pros
Lightweight and silky
Unlike heavy oils, this ingredient absorbs quickly and leaves skin feeling smooth, not sticky or greasy.
Low irritation potential
It is considered very gentle and is often used in products for sensitive or acne-prone skin.
Cons and cautions
Sustainability concerns
It may be sourced from palm oil, which can be linked to deforestation unless certified sustainable.
Less common in budget products
You'll find it more often in mid-to-high-end formulations, so it may not be as accessible in drugstore lines.
Best for
- People with oily or combination skin who want hydration without greasiness
- Anyone looking for a lightweight, non-comedogenic moisturizer
Use caution if
- Those with a known allergy to adipic acid or fatty alcohols (rare)
