Biodegradable microbeads for personal care products and cosmetics

Abstract

Plastic microbeads in cosmetics and personal care products are major contributors to microplastic pollution and pose a significant threat to ecosystems and human health. Biodegradable microbeads, made from synthetic or natural biodegradable polymers, are emerging as promising alternatives with considerable potential for application in the personal care and cosmetics industry. This review focuses on the current alternatives to plastic microbeads and discusses methods for producing biodegradable microbeads for exfoliation. The properties of biodegradable microbeads directly influence both product performance and environmental impacts. Thus, their mechanical properties, stability, biocompatibility, biodegradability, and environmental friendliness are outlined. Additionally, potential future applications of biodegradable microbeads in cosmetics are explored. Finally, this review addresses the challenges and green sustainability prospects of biodegradable microbeads in the cosmetics industry.
