Ingredient review
PPG-70 Glyceryl Ether
INCI: PPG-70 Glyceryl Ether
A gentle, synthetic humectant that draws moisture into the skin without the stickiness of glycerin.
In plain English
PPG-70 Glyceryl Ether is a man-made ingredient that helps your skin hold onto water. It belongs to a family of compounds called glyceryl ethers, which are known for being mild and non-irritating. Think of it as a lightweight moisture magnet that sits on the skin's surface and pulls water from the air or deeper layers, keeping your skin feeling soft and hydrated. Unlike some humectants, it doesn't feel heavy or tacky, making it a good choice for lightweight formulas.

Quick decision guide
Useful, but context matters
PPG-70 Glyceryl 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-70 Glyceryl 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-70 Glyceryl Ether is a synthetic polymer made by reacting propylene oxide with glycerin. The 'PPG-70' indicates the average number of propylene glycol units in the chain, which gives it a specific molecular weight and water-attracting properties.
How it works
It works as a humectant by attracting and binding water molecules to the skin's surface. This helps reduce transepidermal water loss (TEWL) — the natural evaporation of water from your skin — and keeps the outer layer of skin (the stratum corneum) hydrated and flexible. It also has a slight emollient effect, helping to smooth the skin's texture.
Pros
Lightweight hydration
It provides moisture without a heavy or sticky feel, making it ideal for daytime use or under makeup.
Gentle on skin
With a low irritation risk, it's well-tolerated even by sensitive or reactive skin types.
Cons and cautions
Moderate hydration power
It may not be as effective as glycerin or hyaluronic acid for very dry skin, especially in low-humidity environments.
Synthetic origin
Some consumers prefer naturally derived humectants, though PPG-70 Glyceryl Ether is considered safe and non-toxic.
Best for
- People with normal to oily skin who want lightweight hydration
- Those with sensitive skin looking for a gentle humectant
Use caution if
- People with very dry or dehydrated skin may need a more potent humectant
Usage tips
Safety summary
PPG-70 Glyceryl Ether is considered safe for use in cosmetics. It has a low potential for skin irritation and is not known to be comedogenic. No significant safety concerns have been reported in routine cosmetic use.
Research notes
Research on PPG-70 Glyceryl Ether is limited, but it is a well-established ingredient in the cosmetics industry. Its safety has been reviewed by the Cosmetic Ingredient Review (CIR) panel, which found it safe for use in cosmetics. Most evidence comes from formulation studies rather than clinical trials.
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. The Cosmetic Ingredient Review (CIR) panel has deemed it safe for use in rinse-off and leave-on products at typical concentrations.
- Common uses
- Moisturizers, Serums, Cleansers, Body lotions
- Environmental note
- As a synthetic polymer, it is not biodegradable and may accumulate in the environment. However, it is used in low concentrations and is not considered a major environmental concern.
Good to know
- PPG-70 Glyceryl Ether is often used in 'gel-cream' textures for a refreshing, non-greasy feel.
- It is compatible with most other skincare ingredients and rarely causes pilling.
