Ingredient review
Sodium Trehalose Octenylsuccinate
INCI: SODIUM TREHALOSE OCTENYLSUCCINATE
A gentle, sugar-based humectant that helps skin retain moisture and improves the feel of products without common irritation.
In plain English
Sodium Trehalose Octenylsuccinate is a modified version of trehalose, a natural sugar found in plants and microorganisms. In skincare, it acts like a moisture magnet, helping your skin hold onto water. It also makes creams and serums feel smoother and less sticky. Because it's derived from a sugar, it's generally very gentle and unlikely to clog pores or cause irritation.

Quick decision guide
Useful, but context matters
Sodium Trehalose Octenylsuccinate 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 Sodium Trehalose Octenylsuccinate.
- 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 derivative of trehalose, a disaccharide sugar naturally produced by plants and microbes to survive drought. The modification (octenylsuccinate) makes it more stable and effective in cosmetic formulations.
How it works
It forms a thin, flexible film on the skin's surface that slows water loss (transepidermal water loss, or TEWL). At the same time, it attracts moisture from the air (humectant action). This dual action helps keep the skin hydrated and plump. In formulas, it also improves spreadability and reduces the sticky or tacky feel some humectants can leave behind.
Pros
Gentle hydration
Derived from a natural sugar, this ingredient is very well-tolerated and unlikely to cause irritation, making it suitable for sensitive skin.
Improves product feel
It reduces the sticky or tacky sensation that some moisturizers leave behind, so your skin feels smooth and comfortable after application.
Cons and cautions
Less researched than alternatives
Compared to glycerin or hyaluronic acid, there are fewer published studies on this specific derivative, so its long-term benefits are less documented.
Modest hydration alone
At typical use levels, it works best as part of a blend of humectants rather than as a standalone heavy-duty moisturizer.
Best for
- Anyone with normal to dry skin looking for gentle, non-irritating hydration
- People with sensitive or reactive skin who want a moisturizing ingredient that is unlikely to cause breakouts or stinging
Use caution if
- Those seeking a very potent, single-ingredient humectant may prefer glycerin or hyaluronic acid instead
Usage tips
Safety summary
Sodium Trehalose Octenylsuccinate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in regulatory or dermatological reviews.
Research notes
Research on trehalose itself is well-established, showing it protects cells from dehydration and oxidative stress. Studies on the octenylsuccinate derivative are more limited but indicate it functions as an effective humectant and texture modifier in cosmetic formulations.
Common label clues
- Typical concentration
- Typically 0.5% to 5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup primers
- Environmental note
- Trehalose is typically derived from corn starch or other plant sources via fermentation, making it a renewable ingredient. The modification process is chemical but generally considered low-impact.
Good to know
- Trehalose is naturally found in resurrection plants, which can survive extreme dehydration, inspiring its use in skincare for moisture retention.
- This ingredient is often used in 'skin barrier repair' products because it supports the skin's natural moisture balance without disrupting the barrier.
