Ingredient review
Sucrose Polysoyate
INCI: SUCROSE POLYSOYATE
A mild, biodegradable surfactant that cleanses without stripping the skin barrier.
In plain English
Sucrose polysoyate is a cleansing ingredient made by combining sugar (sucrose) with fatty acids from soybean oil. It works like a gentle soap, helping water mix with oil and dirt so they can be rinsed away. Unlike harsher detergents, it is known for being very mild and non-stripping, making it a favorite in gentle or sensitive-skin cleansers.

Quick decision guide
Easy yes for most routines
Sucrose Polysoyate 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 Polysoyate.
- 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 polysoyate is a semi-synthetic surfactant created by esterifying sucrose with soybean oil fatty acids. It belongs to the class of sugar-based surfactants, which are prized for their mildness and biodegradability.
How it works
As a surfactant, sucrose polysoyate reduces the surface tension between water and oil, allowing oily impurities and makeup to be emulsified and washed away. Its large sugar head group makes it less penetrating into the skin, which minimizes irritation and helps maintain the skin's natural moisture barrier.
Pros
Ultra-gentle cleansing
Sucrose polysoyate cleans without stripping the skin's natural oils, making it ideal for daily use on sensitive or dry skin.
Eco-friendly profile
Made from renewable sugar and soybean oil, it is biodegradable and has a lower environmental impact compared to petroleum-based surfactants.
Cons and cautions
Low foam
It produces a modest, creamy lather rather than big bubbles, which may not satisfy those who associate foam with cleanliness.
Higher cost
As a specialty ingredient, products containing sucrose polysoyate often carry a higher price tag than conventional cleansers.
Best for
- People with dry, sensitive, or eczema-prone skin
- Those looking for a gentle, sulfate-free cleanser
Use caution if
- Individuals who prefer a high-foam, bubbly cleanser experience
Usage tips
Safety summary
Sucrose polysoyate is considered very safe for topical use. It has low irritation and sensitization potential, and no significant safety concerns have been reported in cosmetic concentrations.
Research notes
Research on sugar-based surfactants, including sucrose esters, consistently shows they are mild and non-irritating to skin. While specific studies on sucrose polysoyate are limited, the broader class is well-supported by dermatological and safety panel reviews.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions.
- Common uses
