Worldwide actions against plastic pollution from microbeads and microplastics in cosmetics focusing on European policies. Has the issue been handled effectively?

Highlights: • Microplastics in cosmetics • Microplastics' effects on the environment and human health, emphasizing on marine pollution • Worldwide bans and voluntary phase-outs of microbeads in cosmetics, their limitations and review of their effectiveness • European policies against microplastics in cosmetics both in rinse-off and leave-on cosmetics Microbeads are solid primary microplastics < 5 mm in diameter that are added to cosmetic products for cleansing and/or exfoliation of the skin. After use, they are discharged into the drain and end up in Wastewater Treatment Plants (WWTPs), from which they can escape into waters. Once disposed, there is no efficient method of recovery and the environmental conditions do not allow full biodegradation. Focusing mainly on the possible effect of microbeads on the environment and the human health, and taking into account that there have always been alternatives with similar cost, scientists suggested banning microbeads from cosmetic products. Despite the increasing knowledge on the microplastics' effects, the pressure from non-governmental organizations (NGO's) and the increasing public concern, few European and other countries worldwide have taken legislative steps against microbeads, and even fewer against other microplastics used in cosmetic products, mainly because it is a common belief that cosmetic industries responded massively to the call for a phase-out. Although EU acted soon after scientists focused on microbeads' effects by restricting cosmetics with microbeads to bare the EU Ecolabel in 2014, there is still no European-wide ban, which will probably take place as of 2022. Present study offers a thorough literature review on the presence of microbeads in cosmetics up to date, focusing primarily on the actions against their use, and questioning whether future pollution from microbeads or/and microplastics in cosmetics has been successfully handled.
