Ingredient review
PPG-69
INCI: PPG-69
PPG-69 is a gentle synthetic humectant that helps keep skin hydrated without clogging pores, but it offers no unique benefits over more common alternatives.
In plain English
PPG-69 is a man-made ingredient that attracts water to the skin's surface, helping it stay soft and hydrated. Think of it like a moisture magnet — it pulls water from the air or deeper layers of your skin to the outer layer, reducing dryness. It's often used in moisturizers and serums because it's very gentle and unlikely to cause irritation or breakouts.

Quick decision guide
Useful, but context matters
PPG-69 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-69.
- 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-69 is a type of polypropylene glycol, a synthetic polymer made from propylene oxide. It belongs to a family of ingredients known as PPGs (polypropylene glycols), which are used in cosmetics for their ability to hold moisture and improve product texture.
How it works
PPG-69 works as a humectant, meaning it binds water molecules and holds them on the skin's surface. This helps reduce water loss from the skin (transepidermal water loss, or TEWL) and keeps the outer layer of skin hydrated. It also has some skin-conditioning properties, leaving the skin feeling smooth and soft.
Pros
Very gentle on skin
PPG-69 has a low irritation and comedogenic risk, making it a safe choice for sensitive or acne-prone skin types.
Improves product feel
It helps create a smooth, non-greasy texture in creams and serums, enhancing the user experience.
Cons and cautions
Modest hydration power
Compared to glycerin or hyaluronic acid, PPG-69 is less effective at drawing and holding moisture, so it may not be the best choice for very dry skin.
Synthetic origin
As a petroleum-derived ingredient, it may not appeal to those preferring natural or plant-based skincare options.
Best for
- People with sensitive or easily irritated skin looking for a gentle humectant
- Those with oily or acne-prone skin who want hydration without heavy or pore-clogging ingredients
Use caution if
- Anyone seeking a highly effective humectant — glycerin or hyaluronic acid may work better
Usage tips
Safety summary
PPG-69 is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. No significant safety concerns have been reported in regulatory reviews.
Research notes
Research on PPG-69 specifically is limited, but the broader class of polypropylene glycols has been evaluated by the Cosmetic Ingredient Review (CIR) panel, which concluded they are safe for use in cosmetics at concentrations up to 50%. Studies show low skin irritation and sensitization potential.
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 US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed polypropylene glycols and found them safe at typical concentrations.
- Common uses
- Moisturizers, Serums, Cleansers, Hair products
- Environmental note
- PPG-69 is synthetic and derived from petroleum, so it is not biodegradable. Its environmental impact is similar to other synthetic polymers used in cosmetics.
Good to know
- PPG-69 is often used alongside other PPGs or PEGs to adjust product texture and feel
- It is considered safe by major cosmetic safety panels at typical use levels
