Ingredient review
Hexylethylideneamino Benzoate
INCI: HEXYLETHYLIDENEAMINO-BENZOATE
A synthetic UV filter that helps protect skin from sun damage, but its use is limited by regional regulations and potential environmental concerns.
In plain English
This is a man-made ingredient added to sunscreens and other SPF products to absorb UV rays before they can harm your skin. It works like a tiny sponge that soaks up ultraviolet light and turns it into harmless heat. You'll find it listed on sunscreen bottles alongside other active ingredients like avobenzone or octinoxate. While effective, it's not as widely used as some other UV filters because different countries have different rules about which sun filters are allowed.

Quick decision guide
Useful, but context matters
Hexylethylideneamino Benzoate 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 Hexylethylideneamino Benzoate.
- 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 synthetic organic compound belonging to the class of UV filters. It is a derivative of aminobenzoic acid, chemically modified to improve stability and UV absorption properties. It appears as a clear to slightly yellow liquid in its raw form.
How it works
When applied to the skin, it absorbs UV radiation (primarily UVB and some UVA) and converts it into low-level heat, which is then released from the skin. This prevents the UV energy from penetrating deeper and causing DNA damage, sunburn, or premature aging.
Pros
Effective UVB protection
Helps prevent sunburn by absorbing UVB rays, making it a reliable component in sun protection formulas.
Lightweight feel
Unlike some mineral filters, this synthetic ingredient can be formulated into sheer, non-greasy textures that wear well under makeup.
Cons and cautions
Limited regulatory approval
Not approved by the FDA for use in sunscreens in the United States, so you won't find it in US products, which limits your options if you travel.
Environmental persistence concerns
Some studies suggest synthetic UV filters can accumulate in water and affect marine life, though more research is needed to fully understand the impact.
Best for
- People looking for a lightweight sunscreen option
- Those who tolerate synthetic UV filters well and want reliable UVB protection
Use caution if
- Individuals with very sensitive or reactive skin who prefer mineral-only sunscreens
Usage tips
Safety summary
Generally considered safe for topical use in approved concentrations, but not all regulatory agencies have reviewed it. Avoid if you have known sensitivities to chemical sunscreens.
Research notes
Moderate evidence supports its effectiveness as a UVB filter. Environmental and long-term human safety data are still emerging, with ongoing studies on ecotoxicity.
Common label clues
- Typical concentration
- Up to 10% in leave-on products, depending on regional regulations
- Regulatory status
- Approved as a UV filter in the EU and many other countries at concentrations up to 10%. Not currently approved by the US FDA for use in sunscreens.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Broad-spectrum sun protection products
- Environmental note
- Like many synthetic UV filters, there are concerns about its persistence in aquatic environments and potential effects on coral reefs. Some regions have begun restricting certain UV filters for this reason.
Good to know
- This ingredient is more commonly used in sunscreens sold in Europe and Asia than in the US.
- It is often combined with other UV filters to achieve broad-spectrum protection.
