Plastic microbeads are solid plastic particles less than 5mm in diameter
Plastic microbeads are solid plastic particles that measure less than 5mm in diameter. They are manufactured with different sizes and shapes and are not comprised of a single chemical composition but a variety of compositions, including polyethylene, polyethylene terephthalate, polypropylene, polyamide, polyesters, polystyrene, and polyvinyl chloride. These tiny plastic particles are added to a range of products, including rinse-off cosmetics, personal care, and cleaning products. They serve various purposes, such as exfoliation, abrasion, bulking, shelf-life extension, and controlled release of active ingredients.
Due to their small size, microbeads can pass through most wastewater treatment systems and end up in rivers, lakes, and oceans, contributing to plastic pollution. They persist in the environment, harming marine life and potentially impacting human health through the consumption of contaminated seafood.
To address these environmental concerns, several countries and states have implemented legislation banning the use and manufacture of microbeads in personal care and cosmetic products. These include the Microbead-Free Waters Act in the United States, similar bans in Canada, Australia, and various European countries. The best way to mitigate the impact of microbeads is to prevent their entry into the environment, and ongoing efforts are being made to phase out their use and find alternative ingredients.
While the negative effects of microbeads on marine life are widely recognized, there is limited evidence regarding their direct impact on human health. However, the presence of microbeads in personal care products and their subsequent release into the environment highlight the importance of comprehensive risk assessments and effective wastewater treatment processes.

They are used in health and beauty products, including soap and toothpaste
Microbeads are tiny pieces of plastic found in many health and beauty products, including soap and toothpaste. These plastic beads, mostly made from polyethylene, are used in products like scrubs and toothpaste and have specific functions such as scrubbing, peeling, or exfoliating. They are usually spherical and smaller than 5mm in diameter, with the exact size varying across different definitions. For example, the Environment and Climate Change Canada (ECCC) defines microbeads as plastics with diameters between 0.5 microns and 2 millimeters.
The presence of microbeads in health and beauty products has raised concerns due to their potential harm to the environment and marine life. After use, these microbeads go down the drain and may not be effectively filtered by treatment systems, ultimately ending up in lakes and oceans. This has led to worries that small organisms in the marine food web may mistake these plastic particles for food, resulting in negative consequences for various species and the ecosystem as a whole.
Recognizing these environmental concerns, several countries and states have taken steps to ban or restrict the use of microbeads in rinse-off cosmetic products. For instance, the Microbead-Free Waters Act of 2015 in the United States prohibits the manufacture and interstate commerce of rinse-off cosmetics containing intentionally added plastic microbeads. Similarly, Canada, through Bill C-680, and the state of Illinois in the US have implemented bans on the sale and manufacture of products containing microbeads.
Despite these efforts, it is important to note that not all plastic ingredients have been banned, and microplastics remain prevalent in cosmetics and personal care products. Consumers can utilize apps like Beat the Microbead to identify products containing microplastics and make more informed choices. Additionally, some companies have taken initiative by voluntarily phasing out plastic microbeads from their products, demonstrating a growing awareness of the issue within the industry.
While the focus has primarily been on the environmental implications, there are also potential human health risks associated with microplastics in health and beauty products. Animal studies have shown that microplastics can enter the bloodstream and accumulate in various organs, potentially causing blockages and inflammation. However, more research is needed to fully understand the extent of these health risks.

They are harmful to marine life and the environment
Plastic is the most common type of marine debris found in our oceans and the Great Lakes. Plastic debris can come in all shapes and sizes, but those smaller than 5mm in length are called "microplastics". Microbeads are a type of microplastic. They are small, solid, manufactured plastic particles that are less than 5mm in diameter and do not degrade or dissolve in water.
Microbeads are harmful to marine life and the environment in several ways. Firstly, they can be ingested by a variety of marine inhabitants due to their microscopic size, causing adverse health effects. They can also be mistaken for food by aquatic life and birds. Secondly, microbeads have the potential to absorb various harmful hydrophobic pollutants from the surrounding environment. This ability to adsorb toxins can lead to the indirect transfer of contaminants up the marine food chain. As a result, microbeads can have a damaging effect not only on marine life but also on human health, as contaminants can accumulate in species that are part of the human food chain.
The negative impacts of microbeads on the environment are a recent discovery, and while there is ongoing debate about the extent of their harm to marine life, there is a consensus that they are harmful. Current methods for cleaning microplastics from the ocean are inefficient, unscalable, and economically unfeasible, which further intensifies the harms they pose.
To address the issue of microbead pollution, various countries and states have implemented legislation banning the manufacture, sale, and use of products containing microbeads. These include Canada, the United States (at the federal level and in several states), Australia, and the United Kingdom. The best way to mitigate the impact of microbeads is to prevent them from entering the environment, and public education about the harmful effects of plastic debris is crucial.

Due to their environmental impact, many countries and states have banned or are phasing out microbeads. The negative impacts of microbeads are a recent discovery, and while there is debate about the extent to which they harm marine life, there is a consensus that they are harmful. Current methods for cleaning microplastics from the ocean are inefficient and expensive, so the best way to reduce pollution is to prevent microbeads from entering the environment.
In 2012, the North Sea Foundation and the Plastic Soup Foundation launched an app to allow Dutch consumers to check whether personal care products contain microbeads. This was further developed for international audiences in 2013 by the United Nations Environment Programme and UK-based NGO Fauna and Flora International.
At a federal level, the Microbead-Free Waters Act of 2015 prohibits the manufacture and introduction into interstate commerce of rinse-off cosmetics containing intentionally added plastic microbeads. This came into effect in July 2017, with sales of such products banned from July 2018. Illinois was the first U.S. state to enact legislation banning the manufacture and sale of products containing microbeads, with other states following suit.
Several other countries have also banned microbeads from rinse-off cosmetics, including Canada, France, New Zealand, Sweden, Taiwan, and the United Kingdom. The Netherlands was the first country to announce its intention to be free of microbeads in cosmetics by the end of 2016. The British government banned the production of microbeads in rinse-off cosmetics and cleaning products in England effective 9 January 2018. The New South Wales state government banned the supply of rinse-off personal care products containing microbeads, effective from 1 November 2022.
The EU Commission has planned a ban on intentionally added microplastics in cosmetics, personal care products, detergents, and cleaning products by 2020. They have also proposed that companies release fewer microplastics when producing products such as textiles, tyres, paint, and cigarette butts.

They are not easily captured by wastewater treatment systems
Microbeads are small, solid, manufactured plastic particles that are less than 5mm in diameter and do not degrade or dissolve in water. They are commonly added to rinse-off cosmetic, personal care, and cleaning products. Due to their small size, microbeads are not effectively captured by most wastewater treatment systems. If they are washed down the drain, they can pass through wastewater treatment plants untreated and end up in rivers, lakes, and oceans, causing significant harm to marine life and the environment.
The inability of wastewater treatment systems to capture microbeads is a pressing issue. These tiny plastic particles can persist in the environment for long periods, impacting marine ecosystems and human health. Microbeads have the capacity to adsorb toxins, which can then be transferred up the marine food chain. This poses a risk not only to aquatic organisms but also to humans who may consume contaminated seafood.
The negative consequences of microbeads on the environment and marine life have led to a growing recognition of the importance of preventing their release into waterways. Efforts to reduce the use of microbeads in consumer products and promote natural alternatives have gained traction. Several countries and states have implemented bans or voluntary phase-outs of microbeads in personal care, cosmetic, and cleaning products. These initiatives aim to stop microbeads from entering wastewater streams and mitigate their environmental impact.
While some progress has been made, the challenge of effectively capturing and removing microbeads from wastewater remains. Traditional wastewater treatment methods often fail to remove microplastics, including microbeads, allowing them to contaminate water bodies. However, recent studies have explored innovative solutions, such as electrocoagulation (EC), which has shown promising results in removing microplastics from wastewater streams.
To address the issue of microbeads in wastewater, a combination of approaches is necessary. While legislative actions and voluntary phase-outs are crucial in reducing the use of microbeads, it is equally important to invest in research and technology for effective removal and degradation methods. By exploring alternatives like PHA-based microbeads that biodegrade in wastewater treatment facilities, we can minimize the environmental impact and protect our precious water resources.
