What it is
A synthetic ester formed from stearyl alcohol, PPG-3 myristyl ether, and dimer dilinoleic acid. It functions as a non-greasy emollient and film-forming agent.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, soft feel. It also forms a thin, breathable film that helps reduce water loss, keeping skin hydrated longer without feeling sticky or heavy.
Pros
Lightweight feel
Unlike heavy oils, this ingredient spreads easily and leaves a silky, non-greasy finish, making it ideal for daytime moisturizers and makeup.
Low irritation risk
It has a very low irritation and comedogenic rating, so it's generally safe for sensitive and acne-prone skin types.
Cons and cautions
Synthetic origin
It is lab-made, which may be a turn-off for those seeking fully natural or organic skincare products.
Limited long-term data
While considered safe, there is less independent research on this specific ingredient compared to more common emollients like squalane or jojoba oil.
Best for
- People with normal to dry skin looking for lightweight moisture
- Those who prefer non-comedogenic emollients
Use caution if
- Individuals strictly avoiding synthetic ingredients
