Tri-C12-13 Alkyl Citrate
INCI: TRI-C12-13 ALKYL CITRATE
A gentle, non-greasy emollient that improves skin feel and product spreadability without clogging pores.
In plain English
Tri-C12-13 Alkyl Citrate is a synthetic ingredient made from citric acid and fatty alcohols. It acts as an emollient, meaning it helps soften and smooth the skin by forming a light, breathable film that reduces water loss. Unlike heavy oils, it feels silky and non-greasy, making it popular in lightweight moisturizers and sunscreens. It also helps other ingredients spread evenly and gives products a pleasant, velvety texture.

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
An ester formed by combining citric acid with a blend of C12-13 fatty alcohols, resulting in a stable, lightweight oil-like substance used in cosmetics.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smoother feel. It also helps lock in moisture by reducing transepidermal water loss (TEWL), which is the water that evaporates from your skin throughout the day.
Pros
Non-greasy feel
Unlike heavier oils, this ingredient leaves a silky, lightweight finish that won't make your skin feel sticky or shiny.
Low irritation risk
It is considered very gentle and unlikely to cause redness or stinging, even for sensitive skin types.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a drawback if you prefer only naturally derived ingredients in your skincare.
Limited research
While safe, there are fewer published studies on its long-term skin benefits compared to more traditional emollients like shea butter or jojoba oil.
Best for
- People with normal to dry skin looking for lightweight moisture
- Those who prefer non-greasy sunscreens or makeup
Use caution if
- Individuals with known sensitivity to synthetic esters (rare)
- Strict adherents to 100% natural formulations
