  • Publication number: 20250107978
    Abstract: A method for skin protection by applying a zinc oxide-on-silicate platelet composite (ZnO/NSP composite) is formulated in a cosmetic composition, to the skin of a subject. The ZnO/NSP composite is made of silicate platelet and ZnO particles adsorbed thereon, in which the ZnO particles are created by the dehydration of Zn(OH)2 formed on the silicate platelet. The ZnO particles adhering on the silicate platelet can effectively improve the dispersibility of zinc oxide particles in water, and the average particle size can reach near nanometer size. Moreover, the ZnO/NSP composite exhibits better antimicrobial and UV light-absorbing properties than ZnO itself, and are not toxic or irritating to the skin.
