Ingredient review
Tetradecyleicosanol
INCI: TETRADECYLEICOSANOL
A gentle, non-greasy emollient that helps soften and smooth the skin without clogging pores.
In plain English
Tetradecyleicosanol 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. It is not the same as drying alcohols like SD alcohol; instead, it is a moisturizing ingredient that improves the texture of creams and lotions, making them feel silky and spread easily. Because it is non-greasy and has a low risk of irritation or clogging pores, it is often used in products for sensitive or acne-prone skin.

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 (C34) produced synthetically, used primarily as an emollient and skin conditioning agent in cosmetic formulations.
How it works
It sits on the skin's surface, filling in gaps between skin cells to create a smooth, soft feel. It also helps other ingredients spread evenly and reduces water loss by forming a light protective layer.
Pros
Gentle on skin
Tetradecyleicosanol has a very low irritation risk, making it suitable for sensitive skin types and around the eye area.
Non-comedogenic
Unlike some heavier oils, this ingredient is unlikely to clog pores, so it works well in formulations for acne-prone or oily skin.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback for consumers who prefer plant-derived or naturally sourced ingredients.
Limited research
Compared to more common emollients, there is less published research on its long-term skin benefits and safety profile.
Best for
- People with dry or rough skin looking for gentle moisture
- Those with sensitive or acne-prone skin who want a non-comedogenic emollient
Use caution if
- Individuals with known allergies to fatty alcohols (rare)
- Those seeking exclusively natural ingredients
