Ingredient review
Cellobiose Octanonanoate
INCI: Cellobiose Octanonanoate
A gentle, sugar-based humectant that helps hydrate skin without stickiness, though research is still emerging.
In plain English
Cellobiose octanonanoate is a lab-made ingredient that combines a natural sugar (cellobiose) with a fatty acid chain. In skincare, it acts like a sponge to pull moisture into the outer layer of your skin, helping it feel softer and more hydrated. Because it's derived from sugar, it's generally very mild and unlikely to cause irritation, making it a good option for sensitive skin types.

Quick decision guide
Useful, but context matters
Cellobiose Octanonanoate 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 Cellobiose Octanonanoate.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic ester created by linking cellobiose (a disaccharide sugar) with octanoic and nonanoic fatty acids. It is designed to be a non-sticky, water-binding ingredient for cosmetic formulations.
How it works
Cellobiose octanonanoate attracts water molecules from the environment or deeper skin layers and holds them near the skin's surface. Its fatty acid portion also helps it spread smoothly and may provide a light emollient effect, improving skin feel without greasiness.
Pros
Gentle hydration
Derived from sugar, it is very mild and unlikely to cause stinging or redness, even on sensitive or compromised skin.
Non-sticky feel
Unlike some humectants, it leaves a smooth, silky finish that doesn't feel tacky or heavy on the skin.
Cons and cautions
Limited research
Cellobiose octanonanoate is relatively new in cosmetics, so there is less independent research on its long-term effects compared to well-studied humectants like glycerin.
Lower potency
At typical use levels, it may not provide as much hydration as more concentrated humectants, so it's often used in combination with other moisturizing ingredients.
Best for
- People with sensitive or easily irritated skin looking for a mild hydrator
- Anyone seeking a lightweight, non-greasy moisturizing ingredient
Use caution if
- Those with very dry or dehydrated skin may need a more potent humectant
Usage tips
Safety summary
Cellobiose octanonanoate is considered safe for topical use in cosmetics. It has low irritation and sensitization potential based on available safety assessments, though comprehensive long-term studies are still limited.
Research notes
Current evidence is primarily from manufacturer safety data and a few formulation studies. Peer-reviewed research on this specific compound is scarce, but its components (cellobiose and fatty acids) are well-tolerated in skin care.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets as a safe ingredient when formulated within standard concentrations.
- Common uses
- Moisturizers, Serums, Toners
- Environmental note
- Cellobiose is derived from plant sugars, making this ingredient a renewable and biodegradable option compared to some petroleum-based humectants.
Good to know
- Cellobiose octanonanoate is often used in 'clean' or minimalist formulations because it is derived from renewable sugar sources.
- It is compatible with most other skincare ingredients and does not typically interfere with actives like vitamin C or retinol.
