Hallstar develops photostabilizer for sun care products
HallStar has developed a photostabilizer said to enhance the water resistance of sun care products and to help formulators meet FDA standards for broad-spectrum claims.

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.
