Ingredient review
PEG/PPG Tocopheryl Ether
INCI: PEG/PPG-100/70 Tocopheryl Ether
A water-friendly version of vitamin E that helps protect skin from environmental damage and keeps it feeling soft.
In plain English
This ingredient is a modified form of vitamin E that has been made water-soluble by attaching PEG and PPG chains. Unlike regular vitamin E oil, it can be easily mixed into water-based products like serums and gels. It works as an antioxidant to help neutralize free radicals from UV and pollution, and it also helps keep skin moisturized and smooth.

Quick decision guide
Useful, but context matters
PEG/PPG Tocopheryl 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 PEG/PPG Tocopheryl 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
A semi-synthetic derivative of vitamin E (tocopherol) that has been chemically modified with polyethylene glycol (PEG) and polypropylene glycol (PPG) to make it water-soluble.
How it works
It acts as an antioxidant by donating electrons to neutralize free radicals, preventing them from damaging skin cells. The PEG/PPG chains also give it humectant properties, helping to attract and retain moisture in the skin.
Pros
Water-soluble antioxidant
Unlike regular vitamin E oil, this ingredient mixes easily into water-based products, making it ideal for lightweight serums and gels that don't feel greasy.
Dual-action skin benefit
It both protects skin from free radical damage and helps keep it hydrated, offering two benefits in one ingredient.
Cons and cautions
Synthetic modification
The PEG/PPG modification is a chemical process, which may not appeal to those seeking entirely natural or minimally processed ingredients.
Potential manufacturing impurities
PEG compounds can sometimes contain trace impurities like ethylene oxide or 1,4-dioxane if not properly purified, though reputable brands ensure high-quality sourcing.
Best for
- Anyone looking for antioxidant protection in a lightweight, water-based formula
- People with oily or combination skin who prefer non-greasy textures
Use caution if
- Individuals with known sensitivities to PEG compounds (rare)
- Those seeking 100% natural or plant-derived ingredients only
Usage tips
Safety summary
PEG/PPG-100/70 Tocopheryl Ether is considered safe for use in cosmetics at typical concentrations. The PEG/PPG modification is well-tolerated by most skin types, and the ingredient has low irritation and comedogenic potential. As with any PEG-containing ingredient, quality control in manufacturing is important to avoid impurities.
Research notes
Vitamin E derivatives are well-studied for their antioxidant and skin-conditioning benefits. While specific studies on this exact PEG/PPG variant are limited, the safety and efficacy of similar tocopheryl ethers are supported by broader research on vitamin E in skincare.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The PEG/PPG components are generally recognized as safe when used in low concentrations.
- Common uses
- Serums, Moisturizers, Anti-aging creams, Sunscreens
- Environmental note
- PEG compounds are not readily biodegradable, but they are used in very small amounts in cosmetics. Some manufacturers are moving toward more eco-friendly alternatives.
Good to know
- This ingredient is often used in combination with other antioxidants like vitamin C for synergistic effects.
- The numbers 100/70 refer to the average number of ethylene oxide and propylene oxide units in the PEG and PPG chains, respectively.
