Ingredient review
C14-22 Alkane
INCI: C14-22 Alkane
A gentle, plant-derived emollient that provides a silky, non-greasy feel without clogging pores.
In plain English
C14-22 Alkane is a mixture of natural hydrocarbons (similar to mineral oil but from plants) that acts as a lightweight moisturizer. It spreads easily on skin, leaving a smooth, velvety finish without feeling heavy or sticky. Because it's derived from plant sources like coconut or palm, it's often considered a more sustainable alternative to silicones or petroleum-based oils.

Quick decision guide
Easy yes for most routines
C14-22 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 C14-22 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
C14-22 Alkane is a blend of straight-chain hydrocarbons (alkanes) with 14 to 22 carbon atoms, typically sourced from plant oils such as coconut or palm. It is produced through a process called hydrogenation, which converts unsaturated plant oils into saturated hydrocarbons that are stable and odorless.
How it works
In a cosmetic product, C14-22 Alkane sits on the surface of the skin, forming a thin, breathable film that reduces water loss (transepidermal water loss, or TEWL). It also helps other ingredients spread evenly and gives the product a luxurious, silky texture. Unlike some oils, it absorbs quickly and does not leave a greasy residue.
Pros
Silky, non-greasy texture
C14-22 Alkane spreads easily and leaves a smooth, velvety finish without the heavy or sticky feel of some oils, making it pleasant to use in daily moisturizers and serums.
Plant-derived and biodegradable
Sourced from renewable plant oils like coconut or palm, this ingredient is biodegradable and often preferred by consumers looking for more sustainable alternatives to petroleum-based emollients.
Cons and cautions
Potential palm oil sourcing
If derived from palm oil, it may contribute to deforestation and habitat loss unless certified sustainable. Look for products that specify sustainable sourcing.
May feel heavy for oily skin
In high concentrations, some people with very oily or acne-prone skin might find it slightly occlusive, though it is generally considered non-comedogenic.
Best for
- People with normal to dry skin looking for lightweight hydration
- Anyone who prefers plant-based alternatives to silicones or mineral oil
Use caution if
- Those with a known allergy to coconut or palm derivatives (rare)
Usage tips
Safety summary
C14-22 Alkane is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. Rare allergic reactions are possible in individuals sensitive to coconut or palm derivatives.
Research notes
While not extensively studied in clinical trials, C14-22 Alkane is widely used in cosmetics and has a strong safety profile based on its chemical similarity to other safe hydrocarbons. Its emollient properties are well-documented in formulation science.
Common label clues
- Typical concentration
- 1% to 20%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU Cosmetics Regulation and the US FDA. It is not classified as a hazardous substance.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup removers, Hair conditioners
- Environmental note
- Derived from renewable plant sources, but sustainability depends on farming practices. Look for RSPO-certified palm or coconut sources to minimize environmental impact.
Good to know
- C14-22 Alkane is often used as a silicone alternative in 'clean' or natural skincare lines.
- It is stable and does not oxidize easily, giving products a longer shelf life.
