Ingredient review
Tristearyl Citrate
INCI: TRISTEARYL CITRATE
A gentle, plant-derived emollient that softens skin and improves product feel without common irritation or clogging concerns.
In plain English
Tristearyl citrate is a waxy ingredient made from citric acid (found in citrus fruits) and stearyl alcohol (a fatty alcohol from coconut or palm oil). In skincare, it works like a lightweight oil that sits on the skin's surface to reduce water loss and leave a smooth, non-greasy feel. It's often used in creams, lipsticks, and conditioners to make the product spread easily and feel silky.

Quick decision guide
Useful, but context matters
Tristearyl 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 Tristearyl 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
Tristearyl citrate is an ester formed by combining citric acid with three molecules of stearyl alcohol. It appears as a white to off-white waxy solid and is commonly derived from plant-based sources like coconut or palm oil.
How it works
When applied to the skin, tristearyl citrate forms a thin, breathable film that helps lock in moisture by reducing transepidermal water loss (water evaporating from the skin). It also acts as a lubricant, making products glide on smoothly and leaving a soft, velvety finish without heavy greasiness.
Pros
Gentle on skin
Tristearyl citrate has a very low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin types.
Improves product feel
It gives creams and lip products a silky, non-greasy texture that spreads easily and leaves a smooth finish.
Cons and cautions
Not a standalone moisturizer
It works as an emollient but does not add water to the skin; you still need humectants like glycerin for hydration.
Sustainability concerns
Often derived from palm oil, which can be linked to deforestation unless certified sustainable sources are used.
Best for
- Anyone looking for a gentle, non-irritating emollient
- People with dry or normal skin who want a soft finish without heavy oils
Use caution if
- Those with a known allergy to citric acid or fatty alcohols (rare)
Usage tips
Safety summary
Tristearyl citrate is considered safe for use in cosmetics at typical concentrations. It has low skin irritation and sensitization potential, and no significant toxicity concerns have been reported in available safety assessments.
Research notes
Safety data on tristearyl citrate is limited but consistent with other fatty acid esters. The Cosmetic Ingredient Review (CIR) panel has reviewed similar esters and found them safe. No peer-reviewed studies specifically on tristearyl citrate were identified, but its chemistry is well understood.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. No known restrictions at typical use levels.
- Common uses
- Moisturizers, Lip products, Hair conditioners, Makeup foundations
- Environmental note
- Sourcing from palm oil can impact rainforests; look for RSPO-certified or coconut-derived versions for a more sustainable choice.
Good to know
- Tristearyl citrate is often used in lipsticks and balms because it provides a smooth, non-tacky feel.
- It is considered a 'green' ingredient by many formulators due to its plant-based origin and mildness.
