Tetradecyloctadecanol
INCI: TETRADECYLOCTADECANOL
A gentle, non-greasy emollient that helps soften skin and improve product texture without clogging pores.
In plain English
Tetradecyloctadecanol is a type of fatty alcohol—a waxy, skin-friendly ingredient that feels smooth and silky on the skin. Unlike drying alcohols, it doesn't strip moisture; instead, it helps your skin feel softer and helps other ingredients spread evenly. It's often used in creams and lotions to give them a luxurious, non-sticky feel.

Quick decision guide
Useful, but context matters
Tetradecyloctadecanol 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 Tetradecyloctadecanol.
- 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 (C32) saturated fatty alcohol produced synthetically, designed to act as an emollient and thickening agent in cosmetic formulations.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, soft feel. It also helps stabilize emulsions (mixtures of oil and water) so the product stays creamy and doesn't separate.
Pros
Non-greasy softness
Leaves skin feeling smooth and hydrated without a heavy or sticky residue, making it ideal for daytime moisturizers.
Low irritation potential
Rated very low on both irritation and comedogenic scales, so it's generally safe for sensitive and acne-prone skin.
Cons and cautions
Synthetic origin
Produced through chemical synthesis rather than from natural plant sources, which may be a drawback for consumers seeking all-natural formulations.
Limited standalone benefit
Works best as a supporting ingredient; it doesn't provide active hydration or anti-aging effects on its own.
Best for
- Anyone looking for a gentle, non-comedogenic moisturizer ingredient
- People with dry or normal skin who want a soft, smooth finish
Use caution if
- Those with a known allergy to fatty alcohols (extremely rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has evaluated similar long-chain fatty alcohols and found them safe. Irritation and allergy are very rare.
Research notes
Long-chain fatty alcohols like tetradecyloctadecanol are well-established as safe emollients. While specific studies on this exact molecule are limited, the broader class is supported by decades of safe use in cosmetics and dermatological testing.
Common label clues
- Typical concentration
- Usually 1% to 10% in leave-on products
- Regulatory status
- Approved for use in cosmetics worldwide, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Moisturizers, Creams, Lotions, Lip products, Makeup
- Environmental note
- Synthetically produced, so it avoids land-use concerns of plant-derived alternatives, but its production relies on petrochemical feedstocks.
Good to know
- Despite the 'alcohol' in its name, it's a fatty alcohol and does not dry or sting the skin.
- It's often used in lip balms and lipsticks to create a smooth, glide-on application.
