Ingredient review
Sodium Glycogen Octenylsuccinate
INCI: SODIUM GLYCOGEN OCTENYLSUCCINATE
A gentle film-forming ingredient that helps lock in moisture and improve skin feel without clogging pores.
In plain English
Sodium Glycogen Octenylsuccinate is a modified version of glycogen, a natural sugar stored in our bodies. In skincare, it forms a thin, invisible film on your skin that helps hold moisture in and keeps irritants out. Think of it like a breathable, lightweight shield that makes your skin feel smooth and hydrated.

Quick decision guide
Useful, but context matters
Sodium Glycogen 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 Glycogen 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic polymer derived from glycogen (a natural polysaccharide) modified with octenylsuccinic acid to improve its film-forming and water-binding properties.
How it works
When applied, it spreads into a flexible, non-occlusive film that reduces water loss from the skin (transepidermal water loss, or TEWL) while still allowing the skin to breathe. It also helps other ingredients stay on the skin longer and gives a silky, non-greasy after-feel.
Pros
Gentle moisture lock
Creates a breathable film that reduces water loss without feeling heavy or sticky, making it suitable for sensitive and oily skin types.
Improves product feel
Gives a silky, smooth finish that helps serums and moisturizers spread evenly and feel more luxurious on the skin.
Cons and cautions
Limited evidence
Compared to classic humectants like glycerin, there is less published research on its efficacy and long-term skin benefits.
Potential tackiness
In high concentrations or layered under heavy creams, it may leave a slightly sticky or tacky residue for some users.
Best for
- People with dry or dehydrated skin looking for extra moisture retention
- Those who prefer lightweight, non-comedogenic moisturizing ingredients
Use caution if
- Individuals with known allergies to modified starches (rare)
Usage tips
Safety summary
Generally recognized as safe for topical use. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic concentrations.
Research notes
Emerging ingredient with limited peer-reviewed studies. Most evidence comes from manufacturer data and formulation testing. Early results suggest good tolerability and moisture retention.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a safe film-forming and skin-conditioning agent.
- Common uses
- Moisturizers, Serums, Masks, Sunscreens
- Environmental note
- Derived from renewable plant sources (glycogen), but the modification process involves chemical synthesis. Biodegradability data is limited.
Good to know
- It is often used in 'second skin' or 'film-forming' products designed to create a protective barrier.
- Because it is derived from glycogen, it is considered a more natural alternative to synthetic film-formers like acrylates.
