Polycrylene is a safe and effective non-active ingredient for suncare applications when an extra boost in SPF/PFA results is needed. Its macromolecular backbone not only provides additional water resistance properties, but also precludes contribution to skin irritation and/or penetration concerns associated with non-polymeric oil soluble UV Filters.
Polycrylene is a low molecular weight copolymer of Adipic Acid and Neopentyl Glycol that is terminated with Cyanodiphenyl Propenoic Acid. It finds application in sun protection formulations that contain Avobenzone, providing photostabilization to improve both SPFA and PFA. It may also improve the sunscreen’s resistance to wash-off.
