What Is Sucrose Tetrahydroxystearate?
Sucrose Tetrahydroxystearate is a specialty ester created by bonding ordinary table sugar (sucrose) with hydroxystearic acid, a fatty acid most often sourced from castor oil. The result is a mild lipid-like molecule that blends the skin-loving feel of plant oils with the water-friendly character of sugar. Sugar esters began attracting attention in the 1990s when formulators looked for biodegradable alternatives to petroleum-derived ingredients, and this particular ester has since found a place in modern “clean” and “green” product lines.
The ingredient is produced through an esterification process: sucrose is reacted with hydroxystearic acid under carefully controlled heat and vacuum, then purified to remove residual catalysts and free acids. The finished material is a soft wax or thick liquid that melts easily into oils and emulsions, making it simple to use during manufacturing.
You’ll most often spot Sucrose Tetrahydroxystearate in moisturizing lotions, rich face creams, overnight masks, lip balms, hand butters, hair conditioners and soothing baby-care formulas. Its sugar-oil hybrid structure lets it glide smoothly over skin while helping products feel comforting rather than greasy, which has made it popular in both prestige skincare and everyday body-care ranges.
Sucrose Tetrahydroxystearate’s Cosmetic Benefits/Uses
In formulations this ingredient plays one key role that delivers several user-friendly advantages.
As an emollient, Sucrose Tetrahydroxystearate fills in the tiny gaps between skin cells to create a soft flexible surface. This helps reduce rough texture, boosts immediate skin comfort and supports a smoother appearance. Because it is derived from sugar and plant oil it also lends a light cushiony after-feel that can balance heavier occlusives, allowing products to feel pampering without leaving a heavy film.
Who Can Use Sucrose Tetrahydroxystearate
This gentle emollient is generally suitable for all skin types. Dry and mature skin benefit most from its smoothing qualities while normal and combination skin appreciate the silky feel it lends without heaviness. Sensitive skin usually tolerates it well thanks to its mild sugar based structure, though anyone with known allergies to castor oil derivatives should stay alert. Acne prone users often do fine with it too because it has a low tendency to clog pores, but those extremely susceptible to breakouts may prefer lighter ingredients.
Sucrose Tetrahydroxystearate is produced entirely from plant sources so it aligns with vegan and vegetarian lifestyles. No animal by products or testing are required for its manufacture which makes it welcome in cruelty free formulas.
Current safety data show no specific risks for pregnant or breastfeeding women when the ingredient is used topically in cosmetics. Absorption through intact skin is minimal. Still, this is not medical advice and anyone who is expecting or nursing should ask a healthcare professional before introducing new products, just to be on the safe side.
The ingredient does not make skin more sensitive to sunlight so you do not have to take extra precautions beyond regular daily sunscreen use. It is also odorless, color stable and plays well with most other skincare actives which keeps formulation conflicts to a minimum.
Potential Side Effects/Adverse Reactions
Responses to topical Sucrose Tetrahydroxystearate can vary from person to person. The points below list potential side effects that are possible yet unlikely for the average user when the ingredient is formulated and used correctly.
- Mild irritation or redness in very sensitive individuals
- Allergic contact dermatitis in users allergic to sugar esters or castor oil derivatives
- Temporary clogged pores or comedones in those highly prone to acne
- Rancid or off odor if a product containing the ester has been stored improperly leading to oxidative breakdown
If you develop any persistent stinging, swelling, itching or breakouts while using a product that contains Sucrose Tetrahydroxystearate stop application and seek guidance from a qualified healthcare provider.
Comedogenic Rating
Rating: 1 / 5
Sucrose Tetrahydroxystearate sits at the low end of the scale because its large sugar-fat structure spreads thinly over skin and is less likely to settle deep into pores. It softens the surface without forming a dense, air-tight film the way heavier plant butters or mineral oil can. In most formulas it appears at modest levels, further reducing any pore-blocking risk.
Overall it is considered suitable for people who are prone to acne or breakouts.
Keep in mind that clogging potential always depends on the full recipe, how often a product is applied and individual skin chemistry.
Summary
Sucrose Tetrahydroxystearate is an emollient that slips between skin cells, fills small gaps and leaves a silky, cushiony feel. Its sugar portion attracts a hint of moisture while the fatty portion smooths rough spots so skin feels soft and comfortable.
The ingredient is not as well known as shea butter or jojoba oil, yet formulators who focus on clean beauty appreciate its plant origin, mildness and light after-feel. You will mostly find it in moisturizers, lip care and baby products where a gentle touch is valued.
Current data show it to be very safe for topical use with a low chance of irritation or pore clogging. As with any new cosmetic, try a small patch first to make sure your skin agrees before applying it all over.
