Ingredient review
PPG-25 Sorbitol
INCI: PPG-25 SORBITOL
A gentle, synthetic humectant that draws moisture to the skin without common irritation.
In plain English
PPG-25 Sorbitol is a lab-made ingredient that helps your skin hold onto water. It works like a magnet for moisture, pulling water from the air into the outer layer of your skin. Because it's a larger molecule, it stays on the surface and doesn't penetrate deeply, making it very gentle and unlikely to cause stinging or irritation. You'll often find it in moisturizers and serums where it helps keep the skin feeling soft and hydrated.

Quick decision guide
Useful, but context matters
PPG-25 Sorbitol 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 PPG-25 Sorbitol.
- 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
PPG-25 Sorbitol is a synthetic polymer derived from sorbitol (a sugar alcohol) and propylene oxide. It is a clear, viscous liquid used primarily as a humectant and skin conditioning agent in cosmetics.
How it works
It attracts water molecules from the environment and binds them to the skin's surface, increasing hydration. Its large molecular size means it stays on the stratum corneum (the outermost skin layer) without penetrating deeper, reducing the risk of irritation.
Pros
Gentle hydration
PPG-25 Sorbitol attracts moisture without penetrating the skin, making it ideal for sensitive or easily irritated skin types.
Low irritation risk
Unlike some smaller humectants, this larger molecule is unlikely to cause stinging or redness, even on compromised skin barriers.
Cons and cautions
Synthetic origin
It is lab-made from petrochemical derivatives, which may not align with preferences for natural or sustainable ingredients.
Humidity dependent
In very dry climates, it can sometimes draw moisture from deeper skin layers if the air is too dry, though this is less common with larger humectants.
Best for
- People with dry or dehydrated skin looking for gentle hydration
- Those with sensitive or reactive skin who want a low-irritation humectant
Use caution if
- Individuals seeking exclusively natural or plant-based ingredients
Usage tips
Safety summary
PPG-25 Sorbitol has a strong safety profile with very low irritation and sensitization potential. It is well-tolerated even by sensitive skin and is not known to be comedogenic.
Research notes
While not as extensively studied as glycerin, PPG-25 Sorbitol is recognized by cosmetic safety panels as a safe humectant. Its large molecular size contributes to its mildness.
Common label clues
- Typical concentration
- Typically 1–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used.
- Common uses
- Moisturizers, Serums, Cleansers, Hair conditioners
- Environmental note
- As a synthetic polymer, it is not biodegradable and may accumulate in the environment. However, it is used in low concentrations and is not considered a major environmental concern.
Good to know
- PPG-25 Sorbitol is often used in combination with other humectants like glycerin for a balanced hydration profile.
- It is considered safe by major cosmetic safety panels at typical use levels.
