Ingredient review
Tetradecylpropionates
INCI: TETRADECYLPROPIONATES
Tetradecylpropionates are gentle emollients that help soften skin without feeling greasy, making them a good choice for lightweight moisturizers.
In plain English
Tetradecylpropionates are a type of ester, a molecule made by combining an alcohol and an acid. In skincare, they work as emollients, which means they fill in the tiny gaps between skin cells, making the skin feel smoother and softer. They are lightweight and absorb quickly, so they don't leave a heavy or sticky feeling. You'll often find them in lotions, creams, and sunscreens to improve texture and spreadability.

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 Tetradecylpropionates.
- 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
Tetradecylpropionates are synthetic esters derived from myristyl alcohol (a fatty alcohol) and propionic acid. They are clear, oily liquids that are used in cosmetics to condition and soften the skin.
How it works
As an emollient, tetradecylpropionates sit on the skin's surface and fill in the spaces between skin cells. This helps to smooth rough patches, reduce water loss, and create a soft, flexible film that makes the skin feel hydrated and comfortable. They also help other ingredients spread more evenly across the skin.
Pros
Lightweight feel
Tetradecylpropionates absorb quickly and leave skin feeling soft without a heavy or sticky residue, making them ideal for daytime use.
Low irritation potential
This ingredient is generally well-tolerated and has a low risk of causing irritation, even for sensitive skin types.
Cons and cautions
Synthetic origin
As a synthetic ester, it may not be suitable for consumers seeking exclusively natural or plant-based formulations.
Low comedogenic risk for some
While the comedogenic rating is low, a small number of acne-prone individuals may still experience breakouts with regular use.
Best for
- People with normal to dry skin looking for lightweight moisture
- Those who prefer non-greasy emollients in their daily moisturizer
Use caution if
- Individuals with known sensitivity to synthetic esters (rare)
- Those strictly avoiding all synthetic ingredients
Usage tips
Safety summary
Tetradecylpropionates are considered safe for cosmetic use with a low risk of irritation or sensitization. They are not known to be toxic or carcinogenic. As with any ingredient, patch testing is recommended for those with very sensitive skin.
