Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
A synthetic ester derived from hydroxystearic acid and benzoic acid, designed to mimic the feel of natural oils while being more stable and less greasy.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smooth, soft texture. It also helps other active ingredients spread more evenly and can improve the overall feel of a product.
Pros
Lightweight feel
Unlike heavy oils, this ingredient absorbs quickly and leaves no sticky residue, making it ideal for daytime use and under makeup.
Low pore-clogging risk
Rated low on the comedogenic scale, it is unlikely to cause breakouts, even for acne-prone skin types.
Cons and cautions
Synthetic origin
Derived from petrochemicals, it may not be suitable for those seeking a fully natural or organic skincare routine.
Limited research
While generally considered safe, there are fewer long-term studies on this specific ester compared to more common emollients like glycerin or jojoba oil.
Best for
- People with normal to oily skin who want lightweight moisture
- Anyone looking for a non-comedogenic emollient in their skincare
Use caution if
- Those who prefer exclusively natural or plant-based ingredients
