Ingredient review
Ethyl PG-Acetal Levulinate
INCI: Ethyl PG-Acetal Levulinate
A gentle, plant-derived emollient that softens skin and improves product feel without clogging pores.
In plain English
Ethyl PG-Acetal Levulinate is a semi-synthetic ingredient made from levulinic acid, which comes from plant sugars. It acts as an emollient, meaning it helps soften and smooth the skin by forming a light, non-greasy film. It also helps other ingredients spread evenly and gives products a silky, pleasant texture. Because it is mild and unlikely to clog pores, it is often used in moisturizers and sunscreens for all skin types.

Quick decision guide
Useful, but context matters
Ethyl PG-Acetal Levulinate 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 Ethyl PG-Acetal Levulinate.
- 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
A semi-synthetic ester compound created by reacting levulinic acid (derived from plant biomass) with propylene glycol and ethanol. It functions primarily as an emollient and skin-conditioning agent in cosmetics.
How it works
It sits on the skin's surface, forming a thin, breathable layer that reduces water loss and makes the skin feel softer. Its chemical structure also helps stabilize other ingredients and improves the spreadability of creams and lotions.
Pros
Lightweight feel
Provides a silky, non-greasy finish that absorbs quickly, making it ideal for daytime moisturizers and sunscreens.
Low irritation potential
Rated low for both irritation and comedogenicity, so it is unlikely to cause breakouts or stinging, even on sensitive skin.
Cons and cautions
Less hydrating for dry skin
As a lightweight emollient, it may not supply enough moisture for very dry or dehydrated skin without pairing with richer ingredients.
Limited research
Compared to classic emollients like glycerin or squalane, there is less published safety and efficacy data for this specific compound.
Best for
- People with normal to combination skin looking for a lightweight moisturizer
- Those with sensitive or acne-prone skin who want a non-clogging emollient
Use caution if
- Individuals with extremely dry skin who need richer, occlusive ingredients
Usage tips
Safety summary
Ethyl PG-Acetal Levulinate 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. As with any new ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Available evidence comes from manufacturer safety data and general knowledge of similar ester emollients. Peer-reviewed studies on this specific compound are limited, but it is structurally related to well-studied levulinic acid derivatives that are considered safe.
Common label clues
- Typical concentration
- Typically used at 1–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets; no known restrictions at typical concentrations.
- Common uses
- Moisturizers, Serums, Sunscreens, Cleansers
- Environmental note
- Sourced from renewable plant biomass, and the ingredient is considered biodegradable, making it a more eco-friendly emollient option.
Good to know
- This ingredient is often used as a 'green' alternative to silicones because it provides a similar silky feel but is biodegradable.
- It is derived from levulinic acid, which can be sourced from renewable plant materials like corn or sugarcane.
