We can all agree that the personal care products we use daily shouldn't harm the environment.
It turns out that microbeads, tiny plastic particles in many beauty products, have concerning ecological impacts when they enter waterways.
In this article, we'll define microbeads, explore why they are problematic, look at legislative efforts to ban them, and consider alternative ingredients to mitigate their environmental effects moving forward.
The Scrutiny of Microbeads in Cosmetics
Microbeads are tiny pieces of plastic, less than 1mm in size, that are added to personal care products like facial scrubs, toothpastes, and shower gels as exfoliants. Their small size allows them to easily pass through water filtration systems after being rinsed down the drain, entering and polluting marine environments. Research has shown microbeads can absorb toxins and harm sea life upon ingestion. This has raised alarm about their environmental impact, prompting activism and policy changes.
Defining Microbeads in Personal Care Products
Microbeads are manufactured solid plastic particles ranging from roughly 0.1-1mm in size. They are frequently made of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA) and nylon. Thanks to their small size and round shape, microbeads provide an effective abrasive surface to exfoliate skin. As a result, they have been extensively used in personal care products like facial scrubs, toothpastes, shower gels and more. It's estimated over 100 tons of microbeads were used in cosmetics annually in the United States prior to policy changes.
The Role of Microbeads in Beauty Regimens
The use of plastic microbeads took off in the 1990s when major cosmetic companies began using them as replacements for natural exfoliants. Reasons included their low cost, small uniform size, and mild abrasiveness. Microbeads provided an inexpensive way to produce smooth, thick texture and a pleasant scrubbing effect in skincare products. They could also be easily molded into spheres unlike crushed nut shells or pumice. For these reasons, microbeads became a ubiquitous additive found in all types of soaps, scrubs, creams and toothpastes.
The Environmental Sciences Weigh in on Microbeads
In recent years, scientific research has revealed the harmful environmental impacts of microbeads. Studies found microbeads passing through sewage treatment plants and accumulating in lakes and oceans in high concentrations. Their small size allows them to be easily ingested by marine life, transferring up the food chain. Research also shows microbeads absorb dangerous pollutants like pesticides and bacteria, concentrating toxins in organisms. These discoveries led to activism against microbeads by environmental groups in the early 2010s.
Why Are Microbeads Harmful to Ecosystems?
When rinsed off, microbeads can enter natural waterways through drainage systems, bypassing filters. They tend to accumulate in enclosed bodies of water rather than dispersing into the ocean. Concentrated microbead pollution coupled with their ingestion by aquatic life can introduce toxins into food chains. This poses threats to entire ecosystems. Studies have shown detrimental effects in animals including inflammation, liver stress, and cell damage from microbead consumption. There are also concerns about microbead aggregation introducing harmful bacteria growth. Preventing microbeads from entering water systems is crucial to mitigate ecological harm.
Are microbeads still used in cosmetics?
New data gathered by Cosmetics Europe in 2018 shows that 97.6% of plastic microbeads used for exfoliating and cleansing purposes in wash-off cosmetic and personal care products were phased out between 2012* and 2017.
This is an encouraging sign that the cosmetics industry has made significant progress in removing environmentally harmful microbeads from their products. Key factors that enabled this transition away from microbeads include:
-
Legislation like the Microbead-Free Waters Act of 2015 in the United States, which banned the manufacturing and distribution of rinse-off cosmetics containing plastic microbeads. Similar bans were enacted in other countries.
-
Consumer pressure and changing attitudes - growing awareness of microplastic pollution led more consumers to demand microbead-free alternatives. Brands responded by reformulating products.
-
Innovation in cosmetics - companies developed natural, biodegradable alternatives to effectively replace microbeads, like salt crystals, crushed nuts, seeds, etc.
So while microbeads are still present in a small percentage of cosmetics, the industry trend is clearly moving towards eliminating this unnecessary source of plastic pollution through regulation, consumer action, and sustainable product development. But continued vigilance is needed to achieve a 100% microbead-free cosmetics sector globally.
Which products contain microbeads?
Microbeads are tiny pieces of plastic that are commonly used as exfoliants in personal care products like facial scrubs, toothpastes, and body washes. According to a 2021 report, some other products that may contain microbeads include:
- Lipsticks and lip glosses
- Eyeliners
- Sunscreens
- Deodorants
- Nail polishes
Microbeads can also be present in a range of abrasive household cleaning products like surface cleaners and laundry detergents.
In 2015, the Microbead-Free Waters Act was passed in the United States, which banned the manufacturing and distribution of rinse-off cosmetics containing plastic microbeads. However, some loopholes still allow certain products with microbeads to be sold. For example, the Act does not cover biodegradable microbeads or products that are not meant to be rinsed off like lipsticks and deodorants.
The Modernization of Cosmetics Regulation Act (MoCRA) of 2022 aims to close these loopholes and expand the definition of cosmetics covered under FDA regulations. This will lead to a more comprehensive ban on microbeads in cosmetic and personal care products in the coming years.
What are microbeads and why are they bad?
Microbeads are tiny pieces of plastic, less than 1mm in size, that are intentionally added to personal care products like facial scrubs, toothpastes, and body washes for exfoliating purposes. However, these tiny plastics can easily pass through water filtration systems and end up polluting waterways and oceans.
Once in the environment, microbeads attract and absorb toxic chemicals and contaminants. They are then ingested by marine life, entering the food chain. Over time, this leads to bioaccumulation and biomagnification, meaning toxins become more and more concentrated as they move up the food chain.
Studies have shown that marine animals with high microplastic loads experience:
- Inflammation
- Liver stress
- Cellular damage
In addition to harming sea creatures, microbeads also negatively impact human health when contaminated seafood is consumed.
Due to these environmental and health impacts, many countries have banned the use of microbeads in rinse-off cosmetics. The US passed the Microbead-Free Waters Act in 2015, while the UK, Canada, and New Zealand implemented similar bans. Many cosmetic companies have also voluntarily phased out microbeads from their products.
However, microbeads still persist in some toothpastes, makeup, and other products in certain regions. Continuing advocacy and legislation is needed for a comprehensive global ban on this unnecessary plastic pollutant. The long-term benefits for marine ecosystems and human health make such efforts imperative.

Are microbeads still used in the US?
The Microbead-Free Waters Act of 2015 banned the manufacturing of rinse-off cosmetics containing plastic microbeads in the US, starting July 2017. This federal law prohibits "the manufacturing, packaging, and distribution of rinse-off cosmetics containing intentionally-added plastic microbeads."
Specifically, the Act bans:
- Plastic microbeads used in facial cleansers, shampoos, and toothpaste
- Plastic particles 5 mm or less in size that are "intentionally added"
The legislation was introduced to curb the flow of microplastics entering waterways. Research found microbeads passing through water treatment plants and polluting lakes and rivers on a massive scale.
While the US has taken action on plastic microbeads, many countries still allow their usage. The Microbeads-Free Seas Act of 2021 aims to build on existing efforts by pushing for a global phase-out.
The FDA reports it is no longer finding microbeads in cosmetics products. However, other microplastics like fibers from clothing may still be present. Critics argue more research is needed to understand the impacts of these materials.
In summary, plastic microbeads have been banned in personal care products in the US since 2017. But the fight against microplastic pollution continues through further policy changes and consumer action. Checking your cosmetic ingredients and choosing natural alternatives is an easy way to avoid exposure and environmental harm.
Microbeads and Microplastics: A Marine Crisis
The Search for Microplastics: From Face Scrubs to the Sea
Microbeads from cosmetics and other personal care products easily pass through water treatment plants and end up flowing into rivers, lakes and oceans. Studies have detected high concentrations of microplastics in wastewater effluent, confirming that most microbeads escape filtration and make their way into natural waterways after use.
Once they enter marine environments, currents and tides cause microbeads to be widely distributed geographically. Research finds microplastics accumulating in gyres and coastal regions across the world. The majority of microbeads from cosmetics persist in waterways because they are resistant to biodegradation.
Plastics and Microplastics in the Marine Environment
Many species of marine life consume microplastics after mistaking them for food. Microbeads accumulate in the digestive tracts of fish, seabirds, turtles, and marine mammals, causing internal physical damage and blocking enzyme production. This leads to malnutrition, intestinal injury, and potentially death.
In addition, toxins from microplastics transferred through the food chain increase cancer risk and endocrine disruption. Floating microplastics also provide surfaces for invasive species and pathogens to thrive, further threatening native marine ecosystems.
Bioaccumulation and the Threat to Marine Biodiversity
Studies confirm microplastics from cosmetics transfer up the marine food chain to larger predators and eventually humans. This process is called bioaccumulation - toxins become more concentrated at higher trophic levels.
Bioaccumulation of hazardous chemicals associated with microplastics poses risks to reproductive health, metabolism, immunity, and genetic integrity. Continued trophic transfer magnifies the potential harm to marine biodiversity over time. Reduced species abundance directly impacts ecosystem stability and services humans depend on.
Sustainability Concerns: The Long-Term Implications
The persistence of microbeads in waterways and ongoing bioaccumulation of toxins have alarming sustainability implications. Firstly, depleted fish stocks from mortality threaten food security and the livelihoods of communities dependent on fisheries. Secondly, disturbance of marine ecosystem balance from declining biodiversity hinders resilience against environmental stressors like climate change. Lastly, the socioeconomic costs of reduced ecosystem services like coastal protection, tourism revenue, and climate regulation present a major sustainability issue expected to grow over time.
In summary, the continued usage of microbeads in cosmetics and their escape into marine environments jeopardizes ecological integrity, species survival, and provision of ecosystem services - all pillars of sustainability requiring urgent action.
Microbeads Ban: The Legislative Response
The Microbead-Free Waters Act of 2015: A Policy Milestone
The Microbead-Free Waters Act of 2015 was a landmark piece of legislation in the United States. Signed into law by President Obama, it banned the manufacturing and distribution of rinse-off cosmetics containing plastic microbeads from July 2017.
This act was significant because microbeads were becoming recognized as a major source of microplastic pollution in waterways. Studies found microbeads passing through water treatment plants and accumulating in lakes, rivers and oceans. Their small size allowed them to be ingested by aquatic life, working their way up the food chain.
The bipartisan Microbead-Free Waters Act was crucial in tackling this issue early on. It led efforts to phase out this avoidable source of microplastics, setting an example for other countries to follow suit.
Global Actions: Microbeads in Cosmetics Banned Worldwide
Since the U.S. microbeads ban in 2015, many other countries have introduced similar legislation:
- The UK banned the manufacture and sale of microbeads in rinse-off personal care products in 2018.
- New Zealand banned microbeads in most cosmetics and personal care products in 2018.
- Canada banned the manufacture, import and sale of toiletries containing plastic microbeads in 2018.
- Taiwan banned microbeads in 2020. South Korea and India also have bans.
- The EU cosmetics regulation prohibits the use of microplastics in rinse-off cosmetic products as of 2020.
This demonstrates the momentum globally to eliminate microbeads and curb microplastic pollution entering waterways through wastewater. Most bans apply to both natural and synthetic polymer microbeads.
Evaluating the Impact of Microbeads Prohibitions
Studies assessing the impact of microbead bans have shown promising results so far:
- One study found a 30-40% reduction of microplastics discharged from U.S. wastewater treatment plants since 2017.
- Countries with bans have seen sharp declines in microbeads found in sewage sludge.
- Bans have effectively halted the input of microbeads into the environment from cosmetic sources.
However, some key issues remain around effectively enforcing regulations:
- Imported products may still contain banned substances.
- Alternative plastic ingredients are being used in place of microbeads.
- Some loopholes allow microplastics in products that are not rinse-off.
Ongoing monitoring and expanding the scope of bans is required.
Modernization of Cosmetics Regulation Act of 2022 (MoCRA)
Recent U.S. legislation like the Modernization of Cosmetics Regulation Act (MoCRA) aims to further strengthen the regulation of cosmetics and personal care ingredients.
Key measures in the act relevant to microplastics include:
- Requiring cosmetic manufacturers to register with the FDA and disclose ingredients.
- Mandating recalls of harmful products.
- Providing FDA authority to suspend registration of non-compliant companies.
This improves oversight and should limit the use of potentially harmful ingredients like microplastics.
Navigating the Ban: Alternatives to Microbeads in Cosmetics
As awareness grows regarding the environmental impact of microbeads in cosmetics, manufacturers are seeking sustainable alternatives that provide similar exfoliating properties without harming marine ecosystems. Several natural options show promise as biodegradable replacements. Additionally, emerging technologies could enable the production of novel cosmetic ingredients with reduced ecological footprints. Ultimately, education and transparency will be key drivers spurring consumer demand for more eco-friendly products.
