Tricaprylyl Citrate
INCI: Tricaprylyl Citrate
A silky, non-greasy emollient that hydrates and smooths skin without clogging pores, ideal for sensitive and oily skin types.
In plain English
Tricaprylyl Citrate is a gentle, oil-like ingredient made from citric acid (found in citrus fruits) and caprylic alcohol (from coconut or palm oil). It spreads easily on the skin, leaving a soft, non-sticky finish. Unlike heavy oils, it doesn't feel greasy and is unlikely to clog pores, making it a favorite in lightweight moisturizers and sunscreens.

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 Tricaprylyl 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
Tricaprylyl Citrate is an ester—a compound formed by combining citric acid with caprylyl alcohol. It is a clear, odorless liquid that acts as an emollient and skin conditioner in cosmetics.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, soft texture. It also helps other ingredients spread evenly and reduces the whitish residue (cast) often left by mineral sunscreens.
Pros
Lightweight feel
Absorbs quickly without leaving a greasy residue, making it ideal for daytime use and under makeup.
Low irritation risk
Rated very low on both irritation and comedogenic scales, so it's safe for sensitive and acne-prone skin.
Cons and cautions
Moderate hydration only
Provides surface softness but may not deliver deep moisture for very dry or dehydrated skin.
Sustainability concerns
Often sourced from palm or coconut oil, which can involve deforestation and habitat loss if not certified sustainable.
Best for
- People with oily or combination skin seeking lightweight hydration
- Those who dislike heavy, greasy textures in moisturizers and sunscreens
Use caution if
- Individuals with very dry skin who need richer, occlusive emollients
Usage tips
Safety summary
Tricaprylyl Citrate is considered very safe for topical use. It has low irritation and sensitization potential, is non-comedogenic, and is not known to be toxic or carcinogenic. No significant safety concerns have been reported in cosmetic concentrations.
Research notes
While not extensively studied alone, tricaprylyl citrate is a well-established emollient in cosmetics. Safety assessments by the Cosmetic Ingredient Review (CIR) and EU SCCS support its safe use. Studies focus on its role as a texture enhancer and cast reducer in sunscreens.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics worldwide, including by the U.S. FDA and EU CosIng database, with no concentration restrictions.
- Common uses
- Moisturizers, Sunscreens, Serums, Makeup, Hair conditioners
- Environmental note
- Derived from plant-based sources (citric acid and caprylic alcohol), but sustainability depends on responsible palm/coconut sourcing. Look for RSPO-certified options.
Good to know
- It is often used in mineral sunscreens to improve texture and reduce the chalky white cast.
- Tricaprylyl Citrate is biodegradable and considered safe for aquatic life at typical cosmetic concentrations.
