30 SUN CARE
the environmental impact, health concerns, and supply shortages associated with conventional UV filters, exploring sustainable alternatives becomes imperative. Lignin, derived from forestry and wood
processing waste, emerges as a promising solution due to its abundance and the utilization of green chemistry techniques. The transformation of lignin into CLP overcomes inherent hurdles, such as heterogeneity, making it a viable option for cosmetic applications. The demonstrated SPF-boosting efficacy of CLP in sunscreen formulations, achieving up to a 50% increase in SPF points, underscores their potential to improve the efficacy and sustainability of sun protection products. The successful demonstration of CLP as
SPF boosters not only marks a significant advancement in cosmetic technology but also aligns with the growing demand for sustainable and eco-friendly beauty solutions. Based on the research, Lignovations has
developed a commercial CLP dispersion marketed as LignoGuard®. This multifunctional cosmetic ingredient is made from upcycled biomass and has received COSMOS and NaTrue approval.
