Ingredient review
Triethylhexyl Citrate
INCI: Triethylhexyl Citrate
A lightweight, non-greasy emollient derived from citric acid that improves product texture and skin feel.
In plain English
Triethylhexyl citrate is an ingredient made from citric acid (found in citrus fruits) and a type of alcohol. It acts as an emollient, meaning it helps soften and smooth the skin by forming a light, breathable film that reduces water loss. Unlike heavier oils, it feels silky and non-sticky, making it popular in lotions, sunscreens, and makeup. It also helps other ingredients spread evenly and can improve the overall texture of a product.

Quick decision guide
Useful, but context matters
Triethylhexyl Citrate 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 Triethylhexyl Citrate.
- 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
Triethylhexyl citrate is an ester — a compound formed by reacting citric acid with 2-ethylhexanol. It is a clear, oily liquid that is used primarily as an emollient and skin-conditioning agent in cosmetics. It is considered a synthetic ingredient, though its starting materials can be plant-derived.
How it works
When applied to the skin, triethylhexyl citrate sits on the surface and fills in tiny gaps between skin cells, creating a smooth, soft feel. It reduces transepidermal water loss (the water that evaporates from your skin) by forming a thin, non-occlusive barrier. This helps keep skin hydrated without feeling heavy or greasy. In formulations, it also acts as a solvent and helps dissolve other ingredients, improving product stability and spreadability.
Pros
Lightweight feel
Unlike heavy oils, triethylhexyl citrate absorbs quickly and leaves a silky finish, making it ideal for daytime moisturizers and sunscreens.
Improves product texture
It helps creams and lotions spread more evenly, so you need less product to cover your skin, and it reduces the white cast in mineral sunscreens.
Cons and cautions
Limited skin benefit beyond feel
While it softens the skin temporarily, it does not provide active hydration or long-term barrier repair like ceramides or hyaluronic acid.
Potential for mild irritation
A small number of people with very sensitive skin may experience slight redness or stinging, especially in high-concentration formulas.
Best for
- People with normal to dry skin who want lightweight moisture
- Anyone looking for a non-greasy emollient in sunscreens or makeup
Use caution if
- Those with known sensitivity to citric acid esters or very reactive skin
Usage tips
Safety summary
Triethylhexyl citrate is generally recognized as safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic potential. Patch testing is recommended for those with very sensitive skin, but adverse reactions are rare.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that triethylhexyl citrate is safe as used in cosmetics. Most evidence comes from formulation studies and safety evaluations rather than clinical efficacy trials.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. No concentration restrictions in most countries.
- Common uses
- Moisturizers, Sunscreens, Makeup, Lip products, Hair care
- Environmental note
- Derived from renewable citric acid and alcohol, it is biodegradable and not considered a persistent environmental pollutant.
Good to know
- Triethylhexyl citrate is often used in 'dry-touch' sunscreens because it reduces the sticky, greasy feel.
- It is considered biodegradable and is not classified as a microplastic.
