Sunscreens rely on UV filters to protect against harmful ultraviolet (UV) radiation, with efficacy measured by the sun protection factor (SPF). Formulation additives, including UV-scattering particles, film formers, and thickeners, play a critical role in enhancing SPF and ensuring product durability. Synthetic options like hollow styrene acrylic copolymer spheres and Triacontanyl Polyvinylpyrrolidone (PVP) were shown to improve UV filter and/or sunscreen performance, but remain under discussion due to their microplastic classification or their synthetic nature. In response, film formers based on renewable raw materials are being sought and are gaining traction as sustainable alternatives. However, some natural waxes can lead to formulation challenges, including recrystallization. This paper introduces Dicocoyl Pentaerythrityl Distearyl Citrate, a film-forming wax derived from sustainably sourced, RSPO-certified palm kernel oil, which facilitates the enhancement of performance and water resistance in sunscreens.
