C14-20 Alkane
INCI: C14-20 Alkane
A gentle, non-greasy emollient derived from plant sources that helps soften skin and improve product texture.
In plain English
C14-20 Alkane is a mixture of lightweight oils (alkanes) made from plant sources like coconut or palm. It feels silky on the skin, absorbs quickly, and leaves no sticky or greasy residue. Think of it as a modern, eco-friendly alternative to silicone oils. It helps other ingredients spread evenly and gives products a smooth, luxurious feel.

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 C14-20 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 saturated hydrocarbons (alkanes) with chain lengths between 14 and 20 carbon atoms, typically derived from renewable plant sources such as coconut or palm oil.
How it works
It sits on the skin's surface, forming a thin, breathable film that reduces water loss (TEWL, or transepidermal water loss — the amount of moisture that evaporates from your skin). It also helps other ingredients spread more evenly and gives a silky, non-greasy feel.
Pros
Lightweight feel
Absorbs quickly without greasiness, making it ideal for daytime use and under makeup.
Plant-derived
Sourced from renewable plant oils, it offers a natural alternative to petroleum-based or silicone ingredients.
Cons and cautions
Light hydration only
For very dry or dehydrated skin, this ingredient alone may not provide enough moisture barrier support.
Sustainability concerns
If derived from palm oil, it may contribute to deforestation unless certified sustainable sources are used.
Best for
- People with oily or combination skin who want hydration without shine
- Anyone looking for a silicone-free, plant-based emollient
Use caution if
- Those with very dry skin may need a richer emollient in addition
