PEG/PPG-14/7 Dimethyl Ether
INCI: PEG/PPG-14/7 Dimethyl Ether
A gentle synthetic humectant that helps your skin hold onto water without feeling sticky or heavy.
In plain English
PEG/PPG-14/7 Dimethyl Ether is a lab-made ingredient that attracts moisture to the skin and helps other ingredients spread smoothly. It feels light and non-greasy, making it a popular choice for hydrating serums and lightweight moisturizers. Unlike some humectants, it doesn't leave a tacky residue, so your skin feels soft and comfortable after use.

What it is
A synthetic polymer made from ethylene glycol and propylene glycol, chemically modified to act as a humectant and solvent in cosmetics.
How it works
It pulls water from the environment or deeper layers of the skin to the surface, boosting hydration. It also helps dissolve other ingredients and improves the texture of a product, making it easier to apply and absorb.
Pros
Lightweight hydration
Delivers moisture without a heavy or sticky feel, ideal for daytime use under makeup.
Improves product texture
Helps serums and creams spread evenly and absorb quickly, enhancing the user experience.
Cons and cautions
Synthetic origin
Made from petrochemicals, which may not align with clean-beauty or natural-product preferences.
Potential irritation at high levels
Though rare, very high concentrations could cause mild stinging or redness in extremely sensitive skin.
Best for
- People with normal to oily skin looking for light hydration
- Anyone who dislikes heavy or sticky moisturizers
Use caution if
- Those with known allergies to PEG compounds (rare)
- Individuals seeking exclusively natural ingredients
