The use of microplastic in personal care products has been banned recently, as the accumulation of microplastic (plastic particles less than 5 mm) is a major concern to marine life and food chain. 

Yet, polymer micro-encapsulation is an effective method to promote the delivery and release of active ingredients without any degradation and oxidation, and finds use in various fields such as pharmaceuticals, cosmetics, food and textiles. 

In this project we will develop a sustainable eco-friendly alternative to these microplastic beads, utilising microalgae-derived alginate biopolymer. First year students will gain their very first research experience leading to publication.
