Ingredient review
Polyacrylamidomethyl Benzylidene Camphor
INCI: POLYACRYLAMIDOMETHYL BENZYLIDENE CAMPHOR
A synthetic UVB filter that helps protect skin from sunburn, but its use is limited to certain regions due to varying regulatory approvals.
In plain English
Polyacrylamidomethyl Benzylidene Camphor is a man-made ingredient that works like a tiny umbrella for your skin. It absorbs ultraviolet B (UVB) rays from the sun, which are the main cause of sunburn and can lead to skin damage over time. You'll find it in some sunscreens and daily SPF products, but it's not approved everywhere—for example, it's not allowed in the U.S. but is used in Europe and other regions. It's generally considered safe and low-irritation, but it's always a good idea to patch-test new sunscreens.

Quick decision guide
Useful, but context matters
Polyacrylamidomethyl Benzylidene Camphor 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 Polyacrylamidomethyl Benzylidene Camphor.
- 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 derived from camphor, chemically modified to absorb UVB radiation. It belongs to the camphor derivative family of sunscreen filters.
How it works
When applied to the skin, it absorbs UVB light energy and converts it into heat, which is then released harmlessly. This prevents UVB rays from penetrating the skin and causing sunburn or DNA damage.
Pros
Effective UVB blocker
Absorbs UVB rays efficiently, reducing the risk of sunburn and short-term skin damage.
Low irritation risk
Generally well-tolerated, making it suitable for sensitive skin types when formulated properly.
Cons and cautions
Limited global approval
Not approved by the U.S. FDA, so it's unavailable in American sunscreens, which can be confusing for international shoppers.
Narrow spectrum
Only covers UVB rays, so it must be paired with other filters (like UVA absorbers) for complete sun protection.
Best for
- People looking for UVB protection in sunscreens
- Those with sensitive skin who tolerate synthetic filters well
Use caution if
- Those seeking a sunscreen approved in the U.S. (check local regulations)
- People who prefer mineral-only sunscreens
Usage tips
Safety summary
Polyacrylamidomethyl Benzylidene Camphor is considered safe for use in cosmetics by the European Scientific Committee on Consumer Safety (SCCS) at approved concentrations. It has low skin irritation and sensitization potential. However, its lack of U.S. approval means it's not available in American products, so users outside the U.S. can use it with confidence.
Research notes
Studies show it is an effective UVB absorber with good photostability. Research is limited compared to more common filters, but existing data supports its safety and efficacy in sunscreen formulations.
Common label clues
- Typical concentration
- Up to 10% in leave-on products, as regulated in some regions
- Regulatory status
- Approved in the EU and many other countries as a UV filter up to 10% in cosmetics. Not approved by the U.S. FDA for use in sunscreens as of 2025.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Sun protection products
- Environmental note
- Some synthetic UV filters have raised concerns about coral reef safety, but specific data on this ingredient is limited. Check for reef-safe labels if you're environmentally conscious.
Good to know
- This ingredient is more common in European and Asian sunscreens than in U.S. products.
- It is often combined with other UV filters like avobenzone or titanium dioxide for broader protection.
- The 'camphor' in its name comes from a natural compound found in camphor trees, but this version is fully synthetic.
