Dodecyltetradecanol
INCI: DODECYLTETRADECANOL
A gentle, non-greasy emollient that softens skin and improves product texture with minimal irritation risk.
In plain English
Dodecyltetradecanol is a type of fatty alcohol that acts as an emollient, meaning it helps soften and smooth the skin by forming a light, breathable film on the surface. Unlike some heavier oils, it feels silky and non-greasy, making it a popular choice in moisturizers, creams, and lip products. It also helps other ingredients spread evenly and gives products a nice, luxurious feel.

Quick decision guide
Useful, but context matters
Dodecyltetradecanol 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 Dodecyltetradecanol.
- 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 long-chain fatty alcohol (C26) produced synthetically for cosmetic use. It is a waxy, solid material at room temperature that melts on contact with skin, providing a smooth, velvety texture.
How it works
When applied, dodecyltetradecanol sits on the skin's surface, filling in tiny gaps between skin cells to temporarily smooth roughness and reduce water loss. It does not penetrate deeply but creates a protective layer that locks in moisture and improves the feel of the product.
Pros
Non-greasy feel
Unlike heavier oils, dodecyltetradecanol leaves a silky, lightweight finish that won't clog pores or feel sticky.
Gentle on skin
With low irritation and comedogenic ratings, it's suitable for sensitive and acne-prone skin types.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for those seeking only naturally derived ingredients.
Limited independent research
Most safety data comes from industry sources, and long-term studies on human skin are sparse.
Best for
- People with dry or dehydrated skin looking for a lightweight moisturizer
- Those with sensitive or acne-prone skin who want a non-comedogenic emollient
Use caution if
- Individuals who strictly avoid synthetic ingredients in their skincare
Usage tips
Safety summary
Dodecyltetradecanol is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, as with any ingredient, patch testing is recommended for those with known sensitivities.
Research notes
Safety assessments for long-chain fatty alcohols, including dodecyltetradecanol, are based on industry data and expert panel reviews. While not extensively studied individually, the class is well-tolerated. More independent research would strengthen the evidence base.
Common label clues
- Typical concentration
- 0.5% to 5%
