Tetradecyloctadecyl Behenate
INCI: TETRADECYLOCTADECYL BEHENATE
A gentle, non-greasy emollient that helps soften and smooth skin without clogging pores.
In plain English
Tetradecyloctadecyl Behenate is a synthetic wax-like ingredient that spreads easily on the skin, creating a smooth, silky feel. It helps lock in moisture by forming a light barrier on the surface, but it's not heavy or sticky. Think of it as a modern, lightweight alternative to natural oils or butters in lotions and creams.

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 Tetradecyloctadecyl Behenate.
- 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 ester made by combining a fatty alcohol (tetradecyloctadecanol) with behenic acid, a fatty acid derived from natural sources like rapeseed oil. It is a solid wax at room temperature but melts on contact with skin.
How it works
It sits on the skin's surface to reduce water loss (transepidermal water loss, or TEWL) and improve skin softness. Its molecular structure allows it to spread evenly without feeling greasy, making it a popular choice for lightweight moisturizers and makeup.
Pros
Lightweight feel
Unlike heavy oils or butters, this ester spreads thinly and absorbs quickly, leaving skin soft without a sticky residue.
Low irritation potential
It is considered very gentle and unlikely to cause stinging or redness, even for sensitive skin types.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for consumers who prefer naturally derived ingredients.
Limited research
While safety data is reassuring, there are fewer independent studies on this specific ester compared to more common emollients like jojoba oil.
Best for
- People with normal to dry skin looking for lightweight hydration
- Those who prefer non-greasy moisturizers and makeup
Use caution if
- Individuals seeking exclusively natural or plant-based ingredients
