A safe, lightweight synthetic oil that helps products glide on smoothly without clogging pores.
In plain English

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 mixture of hydrocarbon chains (10 to 13 carbons long) produced through petroleum refining. It is a clear, odorless liquid that acts as a solvent and emollient.
How it works
It dissolves oil-soluble ingredients and helps them blend into a smooth product. When applied, it spreads easily and then evaporates, leaving a light, non-greasy feel. It also helps other ingredients penetrate the skin's surface more effectively.
Pros
Lightweight feel
It evaporates quickly, leaving no heavy or sticky residue, which is great for oily skin types.
Low pore-clogging risk
Rated low on the comedogenic scale, so it is unlikely to cause breakouts for most people.
Cons and cautions
Petroleum-derived
It is a synthetic ingredient made from crude oil, which may not align with natural or eco-conscious preferences.
Potential for dryness
Because it evaporates, it can sometimes strip natural oils if used in high amounts without added moisturizers.
Best for
- People with oily or combination skin who want a lightweight feel
- Anyone using makeup removers or cleansing oils
Use caution if
- Those who prefer exclusively plant-based or natural ingredients
