Ingredient review
Isobutyl Palmitate
INCI: Isobutyl Palmitate
A lightweight synthetic emollient that softens skin but may clog pores for some people.
In plain English
Isobutyl Palmitate is a man-made oil-like ingredient that helps moisturizers and makeup feel smooth and spread easily on your skin. It's similar to natural palm oil but created in a lab. While it works well for many, it has a moderate chance of clogging pores, so if you're prone to breakouts, you might want to patch-test first.

What it is
Isobutyl Palmitate is an ester made by combining isobutyl alcohol with palmitic acid, a fatty acid found naturally in palm oil. It is a clear, odorless liquid that mimics the feel of natural oils on the skin.
How it works
It sits on the skin's surface to reduce water loss and soften the outer layer, making skin feel smoother. It also helps other ingredients spread evenly and gives products a silky, non-greasy texture.

Isobutyl Palmitate gives a silky, non-greasy texture that many people find pleasant in moisturizers and makeup.
Improves product performance
