According to the company, PolycryleneS1 allows formulators to combine active ingredients once considered too photo-unstable to be effective and replaces the triplet-quenching portion of Polycrylene (INCI: Polyester-8) with a singlet-state quencher.
Like Polycrylene, the photostabilizer is also a film-forming polymer that enhances the substantivity of sunscreen formulations.
“The sun is a powerful adversary to many active ingredients. For instance, it makes UV filters like avobenzone start to lose effectiveness almost immediately upon exposure,” says Hallstar President John Paro.
“Innovative photostabilizers like PolycryleneS1 helps skin and sun care formulators meet and exceed consumer requirements for better UVA and UVB protection in a product that’s easy to apply and a pleasure to wear," he added.
