Journal of Bioresources and BioproductsSep 27 2024 In a significant breakthrough for the cosmetics industry, researchers have developed a new type of sunscreen using lignin, a naturally abundant polymer, and titanium dioxide . The study, led by Yarong Li and Zhiguang Tang, was published in the Journal of Bioresources and Bioproducts and details the innovative use of a dual-modified lignin sub-microsphere to enhance the SPF and improve the color of sunscreens.
The results were impressive. Sunscreens prepared with 10% AL-g-MBBT3 demonstrated an SPF of 42.93, a significant increase from the 4.74 SPF of unmodified AL. Moreover, the color of the modified lignin-based sunscreen was considerably lighter, with a color difference value of 45.6, compared to the 49.5 ΔE of unmodified AL, making it more appealing for cosmetic use.
