Bis-Hydroxyethyl Tocopherylsuccinoylamido Hydroxypropane

A gentle, water-friendly form of vitamin E that helps protect skin from environmental damage without the greasy feel of traditional vitamin E oil.

In plain English

This is a modified version of vitamin E that can be easily mixed into water-based products like serums and lightweight moisturizers. Regular vitamin E oil is thick and greasy, but this version is designed to dissolve in water, making it much more pleasant to use in everyday skincare. It still provides the same antioxidant benefits—helping to neutralize free radicals from sun exposure and pollution—but in a format that feels light on the skin.

Quick decision guide

Useful, but context matters

Bis-Hydroxyethyl Tocopherylsuccinoylamido Hydroxypropane 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 Bis-Hydroxyethyl Tocopherylsuccinoylamido Hydroxypropane.
Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic molecule created by chemically bonding vitamin E (tocopherol) with a water-soluble group. This makes it stable in water-based formulas and allows it to penetrate the skin more easily than plain vitamin E oil.

How it works

Once applied to the skin, the molecule is thought to break down slowly, releasing active vitamin E. This vitamin E then acts as an antioxidant, neutralizing free radicals that can cause premature aging and skin damage. Its water-soluble nature also means it can be formulated into clear, non-greasy products.

Pros

Water-soluble vitamin E

Unlike standard vitamin E oil, this derivative mixes easily into water-based serums and gels, so you get antioxidant benefits without a heavy, greasy residue.

Gentle for most skin types

It has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin that might react to other antioxidants.

Cons and cautions

Less studied than plain vitamin E

Most research on vitamin E's skin benefits uses the oil form. There is less published data specifically on this derivative's effectiveness in cosmetic products.

Potential for slower release

The modified structure must be broken down by the skin to release active vitamin E, which may mean the antioxidant effect is delayed or less potent compared to direct application of vitamin E oil.

Best for

Anyone looking for antioxidant protection in lightweight, water-based products
People with oily or acne-prone skin who find vitamin E oil too heavy

Use caution if

Those with a known allergy to vitamin E or its derivatives

Usage tips

Use in the morning under sunscreen to boost antioxidant protection against UV and pollution.

Layer with other antioxidants like vitamin C for a more comprehensive defense against free radicals.

Safety summary

This ingredient is considered safe for cosmetic use with low irritation and comedogenic potential. It is a well-tolerated derivative of vitamin E, though individuals with a known allergy to vitamin E should patch test first.

Research notes

While vitamin E itself is extensively studied for skin health, specific research on this water-soluble derivative is limited. Available evidence suggests it functions as an antioxidant and skin conditioner, but more studies are needed to confirm its efficacy compared to traditional vitamin E.

Common label clues

Typical concentration: 0.1% to 1%
Regulatory status: Approved for use in cosmetics in the US, EU, and many other regions. It is considered safe at typical use levels.
Common uses: Serums, Moisturizers, Eye creams, Sunscreens
Environmental note: As a semi-synthetic ingredient, its environmental impact depends on the manufacturing process. It is not known to be a significant environmental concern at cosmetic use levels.

Good to know

This ingredient is often listed near the middle or end of an ingredient list because it is used at low concentrations.
It is sometimes combined with other vitamin E forms to provide both immediate and sustained antioxidant activity.
