A new degradable microbead could soon replace plastic exfoliants in skin cleansers.
The polymer spheres effectively remove permanent marker and eyeliner on animal skin samples and break down into molecules similar to sugars and amino acids, researchers report December 6 in Nature Chemical Engineering. The beads offer a more environmentally friendly alternative to microplastic beads, the scientists say.
In 2015, the United States banned companies from adding plastic microbeads to personal care products that get rinsed down the drain to prevent them from entering waterways where marine life might ingest them. Several countries have implemented similar bans, but others still allow companies to add plastic microbeads as scrubbers and
