Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic ester made from neopentanoic acid and ethylhexyl alcohol. It is a clear, odorless liquid that mimics the feel of natural oils but is more stable and less greasy.
How it works
It sits on the surface of the skin as a thin, non-occlusive film, reducing friction so products apply evenly. It also helps dissolve other ingredients like UV filters and active compounds, improving their spreadability and absorption.
Pros
Lightweight feel
Creates a silky, non-sticky finish that works well under makeup or sunscreen.
Low pore-clogging risk
Rated low on the comedogenic scale, making it suitable for acne-prone skin.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a concern for those seeking plant-based ingredients.
Potential dryness
In high concentrations, it may not provide enough moisture for very dry skin types without additional humectants.
Best for
- People with oily or combination skin who want lightweight hydration
- Anyone who dislikes heavy, greasy moisturizers
Use caution if
- Those with very dry or dehydrated skin may need richer emollients alongside it
