Ingredient review
C14-19 Alkane
INCI: C14-19 Alkane
A gentle, plant-derived emollient that provides a silky feel and helps other ingredients absorb without clogging pores.
In plain English
C14-19 Alkane is a mixture of natural hydrocarbons (similar to mineral oil but from plants like coconut or palm). It acts as a lightweight oil that spreads easily on the skin, making products feel smooth and non-greasy. Unlike some heavy oils, it doesn't leave a sticky residue and is considered very unlikely to clog pores.

Quick decision guide
Useful, but context matters
C14-19 Alkane is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging C14-19 Alkane.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 blend of straight-chain hydrocarbons with 14 to 19 carbon atoms, typically derived from plant sources such as coconut or palm oil. It is a clear, odorless liquid that mimics the texture of silicone or mineral oil but is biodegradable and renewable.
How it works
It sits on the skin's surface to reduce water loss (like a gentle barrier) and improves the spreadability of creams and serums. Because it evaporates slowly, it provides a lasting silky feel without being heavy or greasy.
Pros
Lightweight and silky
It gives a smooth, velvety feel to products without heaviness, making it ideal for daytime use or under makeup.
Low pore-clogging risk
Rated low on the comedogenic scale, so it's unlikely to cause breakouts even for acne-prone skin.
Cons and cautions
Not deeply hydrating
It works as an emollient (softening) but doesn't add significant water content, so it's best paired with humectants like glycerin.
Sustainability concerns
If sourced from palm oil, it may contribute to deforestation unless certified sustainable.
Best for
- People with oily or combination skin who want lightweight moisture
- Anyone looking for a silicone-free alternative in their skincare
Use caution if
- Those seeking very rich, occlusive moisturizers for extremely dry skin
Usage tips
