Trifluoromethylbipyridyl Bromobenzimidazole

INCI: TRIFLUOROMETHYLBIPYRIDYL BROMOBENZIMIDAZOLE

A synthetic UV filter that helps protect skin from sun damage, but its use is limited to certain regions and formulations due to regulatory and stability considerations.

In plain English

This ingredient is a man-made chemical that absorbs ultraviolet (UV) light from the sun, especially the longer UVA rays that can cause premature aging and some UVB rays that cause sunburn. It works like a tiny sponge, soaking up UV energy and turning it into harmless heat, so your skin is less exposed to damage. You'll find it in sunscreens and daily SPF products, but it's not as common as other filters because it's newer and not approved everywhere yet.

Quick decision guide

Useful, but context matters

Trifluoromethylbipyridyl Bromobenzimidazole 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 Trifluoromethylbipyridyl Bromobenzimidazole.
  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

moderate

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

What it is

A synthetic organic compound designed as a broad-spectrum UV filter. It belongs to a class of chemicals that absorb UV radiation and convert it to heat, preventing it from penetrating the skin.

How it works

When applied to the skin, the molecule absorbs UV photons (especially in the UVA range) and releases the energy as heat, reducing the amount of UV radiation that reaches living skin cells. It is often combined with other UV filters to provide balanced protection across the UVA and UVB spectrum.

Pros

Effective UVA protection

Strongly absorbs UVA rays, which are linked to skin aging and long-term damage, making it a good choice for anti-aging sun protection.

Good photostability

When combined with other filters, it can remain stable under sunlight, reducing the need for frequent reapplication compared to some older filters.

Cons and cautions

Limited global approval

Not yet approved by the FDA in the US or by Japanese regulators, so it may be hard to find in products sold in those markets.

Formulation challenges

Requires careful blending with other ingredients to stay effective and not degrade, which can limit its use in simpler products.

Best for

  • People seeking broad-spectrum sun protection
  • Those who prefer synthetic UV filters over mineral ones

Use caution if

  • Individuals with known sensitivity to synthetic UV filters
  • Those looking for sunscreens approved in the US or Japan (check local regulations)

Usage tips

Apply sunscreen containing this ingredient generously 15 minutes before sun exposure.
Reapply every two hours or after swimming, sweating, or towel drying for continued protection.
Pair with other sun-safe habits like seeking shade and wearing protective clothing.

Safety summary

Based on available data, this ingredient is considered safe for use in sunscreens at typical concentrations when used as directed. It has low irritation and comedogenic potential. However, long-term human exposure data is less extensive than for older filters, and regulatory status varies by country.

Research notes

Studies show effective UVA absorption and good photostability in combination with other filters. Research is ongoing to assess its environmental fate and long-term safety, but current evidence supports its use in approved markets.

Common label clues

Typical concentration
Typically 1–5% in sunscreen formulations
Regulatory status
Approved in the European Union and some other regions as a UV filter in sunscreens, but not yet approved by the US FDA or Japanese authorities. Always check local regulations for product availability.
Common uses
Sunscreens, Daily moisturizers with SPF, Broad-spectrum sun protection products
Environmental note
As a synthetic compound, its environmental impact is still being studied. Some UV filters have raised concerns about coral reef safety, but specific data on this ingredient is limited.

Good to know

  • This ingredient is part of a newer generation of UV filters designed to improve UVA protection and stability.
  • It is often used in combination with other filters like octocrylene or bemotrizinol to achieve broad-spectrum coverage.
