Ingredient review
Sucrose Tristearate
INCI: SUCROSE TRISTEARATE
A mild, sugar-based emulsifier that helps blend oil and water in creams without stripping the skin.
In plain English
Sucrose tristearate is a gentle ingredient made from sugar and a fatty acid found in cocoa butter and shea butter. It acts like a bridge between oil and water, so your moisturizer stays smooth and doesn't separate. Because it's derived from natural sources, it's generally very well tolerated by most skin types, including sensitive skin.

Quick decision guide
Useful, but context matters
Sucrose Tristearate 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 Sucrose Tristearate.
- 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
Sucrose tristearate is a sugar ester, meaning it's created by combining sucrose (table sugar) with stearic acid (a saturated fat). The result is a white, waxy powder that helps oil and water mix together in a stable emulsion.
How it works
In a cosmetic formula, sucrose tristearate positions itself at the boundary between oil droplets and water. Its sugar part loves water, and its fatty part loves oil, so it holds the two phases together. This prevents the cream from splitting into watery and oily layers, and it also gives the product a rich, smooth texture that glides onto skin.
Pros
Gentle on skin
Sucrose tristearate has a very low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin types.
Improves product stability
It prevents oil and water from separating, so your cream stays consistent and effective from first use to last.
Cons and cautions
Not for ultra-light textures
If you prefer a watery gel or serum, this ingredient may make the product feel too rich or creamy for your taste.
Sourcing variability
Stearic acid can be derived from animal or plant sources; check the label if you follow a strict vegan or plant-based routine.
Best for
- Anyone looking for a gentle, non-irritating moisturizer
- People with dry or normal skin who want a rich cream texture
Use caution if
- Those seeking a completely water-thin, gel-like texture (this ingredient adds richness)
Usage tips
Safety summary
Sucrose tristearate is considered safe for cosmetic use. It has a low potential for skin irritation or clogging pores, and no significant safety concerns have been raised by regulatory bodies or dermatological research.
Research notes
Research on sucrose esters, including tristearate, shows they are effective emulsifiers with good skin compatibility. Studies indicate low cytotoxicity and no sensitization potential, supporting their use in sensitive-skin formulations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics worldwide, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Moisturizers, Creams, Lotions, Makeup, Sunscreens
- Environmental note
- Sucrose tristearate is biodegradable and derived from renewable resources (sugar cane or sugar beets and plant oils), making it a relatively eco-friendly choice.
Good to know
- Sucrose tristearate is often used in 'natural' or 'clean' beauty products because it's derived from sugar and plant-based fatty acids.
- It is not a surfactant or cleanser — it's strictly an emulsifier and texture enhancer.
