Ingredient review
Glucose Pentaisovalerate
INCI: Glucose Pentaisovalerate
A gentle synthetic emollient that softens skin without heavy greasiness, but research on its long-term benefits is still limited.
In plain English
Glucose Pentaisovalerate is a man-made ingredient that helps moisturizers feel smooth and silky on your skin. It works by forming a light, non-greasy film that locks in moisture and makes your skin feel softer. Think of it as a modern alternative to heavier oils—it gives a nice texture without clogging pores or feeling sticky.

Quick decision guide
Useful, but context matters
Glucose Pentaisovalerate 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 Pentaisovalerate.
- 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
Glucose Pentaisovalerate is a synthetic ester derived from glucose (a natural sugar) and isovaleric acid. It is designed to function as an emollient and skin-conditioning agent in cosmetics.
How it works
It spreads easily over the skin, creating a thin, breathable barrier that reduces water loss (transepidermal water loss, or TEWL) and improves skin softness. Its molecular structure allows it to be absorbed partially, leaving a smooth, non-tacky finish.
Pros
Lightweight feel
Unlike heavier oils, Glucose Pentaisovalerate absorbs quickly and leaves no greasy residue, making it ideal for daytime use or under makeup.
Gentle on skin
With low irritation and comedogenic risk, it is unlikely to cause breakouts or stinging, even for those with reactive skin.
Cons and cautions
Limited research
There are few peer-reviewed studies on this specific ingredient, so its long-term skin benefits are not as well-documented as more traditional emollients.
Synthetic origin
Some consumers prefer naturally derived ingredients, and this synthetic ester may not align with 'clean' or minimalist skincare philosophies.
Best for
- People with normal to combination skin who want a light moisturizer
- Those with sensitive skin looking for a low-irritation emollient
Use caution if
- Anyone seeking a deeply occlusive moisturizer for very dry skin may need a richer alternative
Usage tips
Safety summary
Glucose Pentaisovalerate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Published research on Glucose Pentaisovalerate is sparse. Most information comes from cosmetic ingredient databases and safety assessments, which indicate it is a well-tolerated emollient. More studies are needed to confirm its efficacy compared to other emollients.
Common label clues
- Typical concentration
- Typically used at 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, Lotions, Creams
- Environmental note
- As a synthetic ester, its environmental biodegradability is not well-documented. It is not known to be a significant environmental concern at typical use levels.
Good to know
- Glucose Pentaisovalerate is often used in combination with other emollients to fine-tune product texture.
- It is not a humectant, so it does not actively draw water into the skin—it primarily helps seal moisture in.
