Ingredient review
Sucrose Tetrastearate Triacetate
INCI: Sucrose Tetrastearate Triacetate
A gentle, sugar-derived emulsifier that helps blend oil and water in creams and lotions, giving them a smooth, non-greasy feel.
In plain English
Sucrose Tetrastearate Triacetate is a fancy name for a molecule made from table sugar (sucrose) and stearic acid (a fatty acid found in cocoa butter and shea butter) with a bit of acetic acid (like vinegar) attached. In your skincare, it acts as a bridge between water and oil, allowing them to mix into a stable, creamy lotion. It also helps the product spread easily and feel silky on your skin without leaving a heavy or sticky residue.

Quick decision guide
Useful, but context matters
Sucrose Tetrastearate Triacetate 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 Tetrastearate Triacetate.
- 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
A semi-synthetic ester derived from sucrose (sugar), stearic acid (a saturated fatty acid), and acetic acid. It belongs to a class of ingredients called sucrose esters, which are known for their gentle, skin-friendly properties.
How it works
It works as an emulsifier, meaning it has one end that loves water and another that loves oil. When you mix water and oil in a formula, this ingredient positions itself at the boundary between the two, reducing surface tension and allowing them to form a stable, uniform mixture. This prevents the product from separating into watery and oily layers. It also contributes to a light, smooth texture that glides onto the skin.
Pros
Gentle on skin
Derived from sugar and fatty acids, it has a very low irritation risk, making it suitable for sensitive skin and daily use.
Improves product feel
It gives creams and lotions a silky, non-greasy texture that spreads easily, so you get a pleasant application experience.
Cons and cautions
Not a treatment ingredient
It doesn't provide active skincare benefits like hydration, anti-aging, or brightening—it's purely a formulation helper.
Limited standalone value
You won't find it as a single-ingredient product; its benefits are only realized within a complete formula.
Best for
- Anyone looking for a gentle, non-irritating moisturizer or cream
- People with sensitive or reactive skin who want stable, well-formulated products
Use caution if
- Those seeking a targeted active ingredient (like vitamin C or retinol) should not rely on this ingredient alone
Usage tips
