Ingredient review
Tocophereth-5
INCI: TOCOPHERETH-5
A gentle, water-soluble vitamin E derivative that helps protect skin from environmental stress while adding light hydration.
In plain English
Tocophereth-5 is a modified version of vitamin E that mixes easily with water, unlike regular vitamin E which is oil-based. This makes it simpler to add to water-based products like serums and lotions. It works as an antioxidant, helping to neutralize free radicals from sun exposure and pollution, and also helps keep skin moisturized. Because it's less oily, it's a good option for people with oily or acne-prone skin who want the benefits of vitamin E without the heavy feel.

Quick decision guide
Useful, but context matters
Tocophereth-5 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 Tocophereth-5.
- 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
Tocophereth-5 is a polyethylene glycol (PEG) derivative of tocopherol (vitamin E). The 'eth-5' indicates it has 5 units of ethylene glycol attached, making it water-soluble while retaining the antioxidant activity of vitamin E.
How it works
In a cosmetic product, Tocophereth-5 acts as an antioxidant by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its water-soluble nature allows it to be evenly dispersed in water-based formulas, where it can also help stabilize other ingredients and provide light humectant (moisture-attracting) benefits.
Pros
Water-soluble and lightweight
Unlike oil-based vitamin E, Tocophereth-5 blends easily into water-based products, making it ideal for serums and gel moisturizers without leaving a greasy residue.
Gentle antioxidant protection
It provides a mild antioxidant effect that helps shield skin from daily environmental damage, suitable for most skin types including sensitive skin.
Cons and cautions
Lower potency than pure vitamin E
The chemical modification reduces its antioxidant strength compared to unmodified tocopherol, so it may not be the best choice for targeted anti-aging treatments.
Potential for irritation in PEG-sensitive individuals
Although rare, the PEG component can cause stinging or redness in people with very reactive skin, especially at higher concentrations.
Best for
- People with oily or combination skin who want antioxidant benefits without a heavy feel
- Anyone looking for a gentle, water-soluble antioxidant to add to their routine
Use caution if
- Individuals with known sensitivity to PEG compounds or vitamin E derivatives
- Those seeking a very high-potency antioxidant (pure tocopherol may be more effective)
Usage tips
Safety summary
Tocophereth-5 is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, though individuals with PEG sensitivity should patch test first.
Research notes
Research on Tocophereth-5 specifically is limited, but it is well-established as a safe and effective derivative of vitamin E. Studies on vitamin E derivatives support its antioxidant and moisturizing benefits.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off and leave-on products.
- Common uses
- Serums, Moisturizers, Cleansers, Sunscreens
- Environmental note
- PEG compounds can be persistent in the environment, but Tocophereth-5 is used in low concentrations and is generally considered low-risk.
Good to know
- Tocophereth-5 is often used in combination with other vitamin E forms to balance texture and efficacy.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
