The sequins, which are often used for greeting cards or home decorations, are not sustainable as they are usually made from microplastics.
Scientists at the University of Cambridge have developed an excellent alternative to these products. Their glitter is made from cellulose obtained from the cells of plants, vegetables and fruits. “The sequins will retain all their properties, but will cease to harm the planet, - said Silvia Vignolini, professor of chemistry at the University of Cambridge. - Plus they are safe for children. "
In a recently published work, the researchers described the process of placing cellulose in nanocrystals, which allows the film-like layer to undergo a "structural coloring" process. This phenomenon, also seen in color flickering on the wings of a butterfly, causes light hitting the nanocrystals to scatter in different directions and create unique colors.
Scientists are confident that the production of such sequins can be mass-produced, and this will make a real revolution in the beauty industry.
