Pentaerythrityl Tetralaurate
INCI: PENTAERYTHRITYL TETRALAURATE
A lightweight, non-greasy emollient that softens skin and helps products spread smoothly.
In plain English
Pentaerythrityl Tetralaurate is a synthetic oil-like ingredient made from lauric acid (a fatty acid found in coconut oil) and pentaerythritol. It feels silky and lightweight on the skin, not heavy or sticky. It helps moisturizers and makeup glide on easily and leaves a soft, smooth finish without clogging pores for most people.

Quick decision guide
Useful, but context matters
Pentaerythrityl Tetralaurate 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 Pentaerythrityl Tetralaurate.
- 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 synthetic ester formed by combining pentaerythritol (a sugar alcohol) with four molecules of lauric acid (a fatty acid from coconut or palm oil). It is a clear, odorless liquid oil at room temperature.
How it works
It sits on the skin's surface to reduce water loss (acts as an occlusive) and fills in rough patches, making skin feel softer and smoother. It also helps other ingredients spread evenly and improves the texture of creams and lotions.
Pros
Lightweight feel
Unlike heavy oils, this ester absorbs quickly and leaves a silky finish, making it ideal for daytime moisturizers and makeup.
Low irritation potential
It is generally well-tolerated even by sensitive skin, with a low risk of stinging or redness.
Cons and cautions
Synthetic origin
It is not a natural oil, which may be a drawback for those seeking plant-only ingredients.
Palm oil sourcing
Lauric acid often comes from palm or coconut oil; if from palm, it may involve deforestation concerns unless certified sustainable.
Best for
- People with normal to dry skin looking for a lightweight moisturizer
- Those who prefer non-greasy makeup or lip products
Use caution if
- Individuals strictly avoiding synthetic ingredients or palm-derived components
