Ingredient review
PPG-24 Diglyceryl Ether
INCI: PPG-24 Diglyceryl Ether
A gentle, synthetic humectant that draws moisture to the skin without common irritation or stickiness.
In plain English
PPG-24 Diglyceryl Ether is a lab-made ingredient that helps your skin hold onto water. Think of it like a moisture magnet — it pulls water from the air or deeper layers of your skin to keep the surface hydrated. Unlike some humectants, it feels light and non-sticky, making it a good choice for people who dislike heavy creams.

Quick decision guide
Useful, but context matters
PPG-24 Diglyceryl Ether 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 PPG-24 Diglyceryl Ether.
- 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
PPG-24 Diglyceryl Ether is a synthetic polymer derived from propylene glycol and glycerin. It belongs to a class of ingredients called polyglyceryl ethers, which are known for their ability to attract and retain moisture.
How it works
It works as a humectant by binding water molecules to the outer layer of the skin (the stratum corneum). This helps reduce water loss and keeps the skin feeling soft and plump. It also has mild emollient properties, meaning it can smooth the skin's surface without leaving a greasy residue.
Pros
Lightweight hydration
Provides moisture without the heavy, sticky feel that some humectants can leave, making it ideal for daytime use or under makeup.
Gentle on skin
Has a low irritation and comedogenic risk, so it's unlikely to clog pores or cause redness, even for sensitive skin types.
Cons and cautions
Synthetic origin
It is a lab-created ingredient, which may not align with the preferences of consumers seeking natural or organic skincare.
Limited independent research
Most safety data comes from industry sources, and there are fewer peer-reviewed studies compared to more common humectants like glycerin.
Best for
- People with normal to dry skin looking for lightweight hydration
- Those with sensitive skin who react to common humectants like glycerin
Use caution if
- Individuals who prefer 100% natural or plant-based ingredients
Usage tips
Safety summary
PPG-24 Diglyceryl Ether is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant toxicity has been reported in available studies.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel and the European Chemicals Agency (ECHA) support its use as a skin-conditioning agent. However, most data come from industry-funded studies, and independent long-term research is limited.
Common label clues
- Typical concentration
- Typically 1–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. It is listed on the CosIng database as a safe humectant and skin conditioner.
- Common uses
- Moisturizers, Serums, Cleansers, Toners
- Environmental note
- As a synthetic polymer, it is not biodegradable and may accumulate in water systems. However, it is used in low concentrations and is not considered a major environmental concern.
Good to know
- PPG-24 Diglyceryl Ether is often used in 'water-light' moisturizers and gel creams.
- It is compatible with most other skincare ingredients and rarely causes pilling.
