Polyacrylamidomethyl Benzylidene Camphor
CAS 113783-61-2
Polyacrylamidomethyl Benzylidene Camphor is a newer-generation organic UVB filter built on a polymeric camphor backbone. It is approved in the EU up to 6% but is not approved in the US, Japan, or Korea. EWG rates it 2; its photostability is not characterized in the data here.
Frequently asked questions
What does this filter cover?
It absorbs only in the UVB range, so it contributes to sunburn-wavelength protection. It needs to be combined with UVA filters to achieve broad-spectrum coverage in a finished formula.
Where is Polyacrylamidomethyl Benzylidene Camphor approved?
It is currently approved only in the EU, capped at 6%. It has not been approved by the US, Japan, or Korea, so it appears only in EU-market sunscreens.
Is it a polymeric filter?
Yes. It is built on a polymer backbone, which generally keeps the UV-absorbing groups on the skin surface rather than penetrating, a property often used to reduce systemic exposure.
How does it score on EWG?
EWG rates it 2 on its hazard scale, on the lower end. The data here does not flag it as an endocrine disruptor or as reef-toxic.
