Ingredient review
Glucose Pentaacetate
INCI: Glucose Pentaacetate
A gentle, sugar-derived emollient that helps soften and condition the skin without clogging pores.
In plain English
Glucose Pentaacetate is a modified form of glucose (a natural sugar) that has been chemically altered to make it more stable and better at helping your skin feel smooth and soft. It works by forming a light, non-greasy film on the skin's surface that locks in moisture and reduces water loss. Think of it as a gentle, sugar-based moisturizer helper that won't feel heavy or sticky.

Quick decision guide
Useful, but context matters
Glucose Pentaacetate 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 Glucose Pentaacetate.
- 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
Glucose Pentaacetate is a semi-synthetic ingredient created by reacting glucose with acetic acid. It belongs to a class of compounds called sugar esters, which are known for their mildness and compatibility with skin. It appears as a white to off-white powder or crystalline solid and is used in skincare to improve texture and hydration.
How it works
When applied to the skin, Glucose Pentaacetate forms a thin, breathable film that helps reduce transepidermal water loss (TEWL) — the amount of water that evaporates from your skin. This film also has emollient properties, meaning it fills in the gaps between skin cells to create a smoother, softer surface. Unlike some heavier oils, it doesn't feel greasy and is well-tolerated by most skin types.
Pros
Gentle on skin
Glucose Pentaacetate has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Lightweight feel
Unlike many emollients, it leaves a non-greasy, silky finish that works well under makeup or sunscreen.
Cons and cautions
Moderate hydration
It provides surface-level moisture but may not be enough for very dry skin that needs deeper humectant or occlusive ingredients.
Limited research
Compared to more common ingredients like glycerin, there is less published research on its long-term skin benefits and safety.
Best for
- People with normal to dry skin looking for a light moisturizer
- Those with sensitive or acne-prone skin who want a gentle emollient
Use caution if
- Individuals seeking a very heavy or occlusive moisturizer for extremely dry skin
Usage tips
Safety summary
Glucose Pentaacetate is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available research.
Research notes
Research on Glucose Pentaacetate is limited but consistent with its classification as a mild emollient. Studies on similar sugar esters support its safety and efficacy for skin conditioning.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated it as safe when formulated appropriately.
- Common uses
- Moisturizers, Serums, Creams, Lotions
- Environmental note
- Derived from renewable sugar sources, but the acetylation process involves chemical modification. Biodegradability is expected to be moderate.
Good to know
- Glucose Pentaacetate is often used in combination with other emollients and humectants to create a balanced formula.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel when used as directed.
