Glucopyranosyloxy Propoxy Hydroxybenzophenone

INCI: 4-(2-BETA-GLUCOPYRANOSILOXY) PROPOXY-2HYDROXYBENZOPHENONE

A synthetic UV filter that absorbs harmful rays, but research on its long-term safety is still limited.

In plain English

This ingredient is a man-made chemical that soaks up ultraviolet (UV) light from the sun, helping to prevent sunburn and skin damage. It works like a sponge for UV rays, turning them into less harmful heat. Because it's relatively new in cosmetics, scientists are still studying how it behaves on skin over time.

Quick decision guide

Useful, but context matters

Glucopyranosyloxy Propoxy Hydroxybenzophenone 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Glucopyranosyloxy Propoxy Hydroxybenzophenone.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

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

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A synthetic benzophenone derivative modified with a sugar molecule (glucose) to improve water solubility and skin compatibility. It belongs to the family of organic UV filters.

How it works

When applied to skin, it absorbs UV radiation (especially UVB and some UVA) and converts it into low-level heat, which is then released from the skin. This prevents the UV energy from damaging skin cells and DNA.

Pros

Effective UV absorption

Absorbs both UVB and some UVA rays, reducing the risk of sunburn and long-term skin damage.

Improved formulation flexibility

The sugar modification makes it more water-soluble, allowing for lighter, less greasy sunscreen textures.

Cons and cautions

Limited research

As a newer ingredient, there are fewer peer-reviewed studies on its long-term safety and environmental impact compared to traditional UV filters.

Potential irritation

Although generally low risk, some individuals may experience mild irritation or allergic reactions, especially with prolonged use.

Best for

  • People looking for chemical sunscreen options
  • Those who prefer lightweight, non-whitening sun protection

Use caution if

  • Individuals with known sensitivity to benzophenone derivatives
  • Those who prefer mineral sunscreens

Usage tips

Apply generously 15 minutes before sun exposure
Reapply every two hours or after swimming/sweating
Use as part of a complete sun protection routine including shade and protective clothing

Safety summary

Generally considered safe for topical use at typical concentrations, but long-term human data is limited. Patch testing is recommended for sensitive individuals.

Research notes

Early studies show effective UV absorption and good skin tolerance, but more independent research is needed to fully assess systemic absorption and environmental fate.

Common label clues

Typical concentration
Up to 10% in leave-on products
Regulatory status
Approved for use in sunscreens in several countries, but not yet reviewed by all major regulatory bodies. Always check local regulations.
Common uses
Sunscreens, Daily moisturizers with SPF, Anti-aging products
Environmental note
Like many synthetic UV filters, its impact on aquatic ecosystems is still being studied. Some benzophenones have been detected in water sources, but this specific derivative may have different properties.

Good to know

  • This ingredient is often combined with other UV filters for broader protection
  • It may be listed under different trade names on product labels
