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.
