What You'll Learn
Plastic beads in toothpaste are harmful to the environment
Plastic beads in toothpaste, also known as microbeads, are small plastic particles that are added to toothpastes for decorative purposes and to add abrasive qualities to the product. These microbeads are made from synthetic polymers, including polyethylene, polylactic acid (PLA), polypropylene, polystyrene, and polyethylene terephthalate. While they may not be harmful to human health, as supported by years of clinical research, they are likely harmful to the environment.
Microbeads are an ingredient in a variety of personal care products, including toothpaste, and have multiple purposes. They are used as an exfoliant or abrasive agent, allow for the timed release of active ingredients, add bulk to formulas, and may prolong a product's shelf life. However, their presence in toothpaste contributes to plastic pollution in the environment.
Once released into the environment, microbeads are challenging to remove. They can be ingested by fish, birds, and other wildlife, mistaking them for food. As microbeads soak up pollutants in waterways, they act as sponges for toxins, absorbing pesticides, phthalates, and heavy metals. This leads to the spread of plastic and contaminants up the food chain, including into the fish consumed by humans.
The presence of microbeads in the environment increases the solubility of hydrophobic compounds, which may have adverse effects on aquatic life. While some countries and manufacturers have banned or phased out the use of microbeads in personal care products, they are still prevalent in many toothpastes and other dental care products. It is important for consumers to be aware of the environmental impact of microbeads and choose plastic-free alternatives to promote ecological sustainability.
To address the issue of plastic beads in toothpaste, several countries and organizations have taken action. The Microbead-Free Waters Act of 2015 in the United States banned the manufacturing, delivery, and sale of rinse-off products containing microbeads smaller than 5 millimeters. Similarly, the Bureau of Indian Standards (BIS) banned the use of microbeads in cosmetic products in India in October 2017, with the ban coming into effect in January 2020. Various cosmetic manufacturers have also voluntarily removed or pledged to phase out microbeads from their products. These efforts aim to reduce the environmental impact of microbeads and promote the use of sustainable, biodegradable alternatives.

They are made from polyethylene, a common plastic
Plastic microbeads in toothpaste are made from polyethylene, one of the world's most common forms of plastic. This is the same material used to make plastic bottles and is approved by the FDA as a colour additive in some toothpastes.
Polyethylene is a synthetic polymer and a food additive, though it is not meant to be swallowed or consumed in toothpaste. It is also used to make plastic bottles.
Microbeads are solid manufactured plastic particles smaller than 5mm in size that do not degrade or dissolve in water. They are added to toothpastes for their abrasive qualities, helping to scrub surface stains from teeth. However, choosing a toothpaste that is too abrasive can wear down the outermost layer of teeth, called the enamel.
Due to concerns about their effects on human health and the environment, there has been a movement to ban microbeads. They have been banned in the United States since 2015 and in India since 2017, with many manufacturers replacing them with sustainable, biodegradable options.

They are added for colour and texture
Plastic beads in toothpaste, also known as microbeads, are added for colour and texture. They are made from polyethylene, one of the world's most common forms of plastic, which is also used to make plastic bottles. While they are approved by the FDA as a food additive, there are concerns about their safety for human consumption, especially as they can get lodged in the gums.
Microbeads are an ingredient in a variety of personal care products and are used for several purposes. They act as an abrasive agent, scrubbing surface stains from teeth. They also allow for a timed release of active ingredients, add bulk to formulas, and may prolong a product's shelf life.
However, microbeads have faced scrutiny due to their potential harm to the environment and human health. They are often ingested by fish and other marine animals, acting as sponges for toxins and carrying them through the food chain. This has led to concerns about the health impact of consuming contaminated fish, with some studies suggesting that the plastics in microbeads may act as hormone disruptors.
In response to these concerns, many countries and manufacturers have taken steps to ban or phase out microbeads from their products. Alternatives such as crushed nut shells, apricot kernels, and soy-based beads have been introduced, offering sustainable and biodegradable options that are safer for the environment and human health.

They may be harmful to human health
Plastic microbeads in toothpaste have been a cause for concern regarding their effects on human health. These microbeads are made from polyethylene, one of the world's most common forms of plastic, also used in plastic bottles and approved by the FDA as a food additive. While they are claimed to be safe by some manufacturers, there are concerns about their potential impact on human health.
Firstly, microbeads can get lodged in the gums, as reported by dental hygienists who found plastic pieces in their patients' mouths. This can potentially trap bacteria and lead to oral health issues such as gingivitis. Secondly, when ingested by fish and other marine animals, these microbeads act as sponges for toxins, absorbing pesticides, phthalates, and heavy metals. These contaminated microbeads can then spread up the food chain, leading to the consumption of contaminated fish by humans. According to the Environmental Working Group, the plastics in microbeads are suspected to be hormone disruptors, potentially releasing estrogen-mimicking chemicals into the human body.
While some countries and manufacturers have taken steps to ban or phase out microbeads, they have not completely eliminated all plastic ingredients from their products. It is important to note that the presence of microbeads in toothpaste may not be harmful, but it also does not provide any beneficial effects. Ongoing research is needed to fully understand the potential health implications of ingesting microbeads, and it is advisable to choose toothpaste that does not contain plastic additives.

They are now banned in several countries
Plastic microbeads in toothpaste, which were previously used for decorative purposes and to add abrasive qualities to the product, have now been banned in several countries due to their harmful effects on the environment and potential health concerns.
In the United States, the Microbead-Free Waters Act of 2015 outlawed the manufacturing, delivery, and sale of any rinse-off products containing microbeads smaller than 5 millimeters, including toothpastes and cosmetics. This ban was implemented to address the issue of plastic pollution in waterways and its impact on marine life.
Similarly, in India, the Bureau of Indian Standards (BIS) banned the use of microbeads in cosmetic products in October 2017, with the ban coming into effect in January 2020. This ban was enforced by the Central Drugs and Standards Control Organisation.
Other countries and states that have taken steps to ban or phase out microbeads include Illinois, Colorado, Maine, New Jersey, and several other US states. Environmentalists have advocated for more comprehensive measures, as some laws leave loopholes for biodegradable plastics, and there are currently no plastics that consistently break down in marine environments.
The movement to ban microbeads has gained momentum due to concerns about their potential effects on human health. Microbeads have been found to act as sponges for toxins, absorbing pesticides, phthalates, and heavy metals, and carrying them through the food chain. They can be ingested by fish and other marine animals, leading to the contamination of seafood consumed by humans. Additionally, there are concerns that microbeads may trap bacteria and contribute to oral health issues such as gingivitis.
While some toothpaste brands have voluntarily phased out microbeads, the presence of microplastics in dental care products remains a concern. Consumers now have a growing range of plastic-free and environmentally friendly alternatives to choose from, ensuring that their oral care routine is both effective and sustainable.
