What it is
Diethylhexyl Malate is an ester derived from malic acid (found in apples) and 2-ethylhexanol. It is a clear, colorless liquid that mimics the feel of natural oils but is more stable and less greasy.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, soft texture. It also helps other ingredients like sunscreen filters or pigments spread evenly and last longer.
Pros
Lightweight feel
Unlike heavier oils, Diethylhexyl Malate absorbs quickly and leaves no sticky or greasy residue, making it ideal for daytime use and under makeup.
Improves product texture
It helps creams and sunscreens glide on smoothly, reducing drag and pilling, so your skincare routine feels more pleasant.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a turn-off for consumers who prefer 100% naturally derived ingredients.
Low but possible irritation
While generally very safe, a small number of people with extremely sensitive skin might experience mild redness or stinging.
Best for
- Anyone who prefers lightweight, non-greasy moisturizers
- People with oily or combination skin looking for a silky finish
Use caution if
- Those strictly avoiding all synthetic ingredients
