Microbead

This article is about plastic microspheres commonly used in cosmetics. For microbeads of varying composition that are used in research, see Microbead (research). For other uses, see Microsphere (disambiguation).

Microbeads are plastic microspheres that are widely used in cosmetics as exfoliating agents and personal care products such as toothpaste, as well as biomedical and health science research, microscopy techniques, fluid visualization and fluid flow analysis, and process troubleshooting.[1] They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene.[2][3]

In the United States, microbeads are defined as less than five millimeters in its largest dimension.[4] Microbeads are commercially available in particle sizes from 10 micrometres (0.00039 in) to 1 millimetre (0.039 in). Low melting temperature and fast phase transitions make this material especially suitable for creating porous structures in ceramics and other materials. Microbeads pose an environmental hazard when disposed of in waste water. Because they pass through sewage treatment plants without being filtered out, their disposal has resulted in plastic particle water pollution with microplastics. Several jurisdictions have regulated the use of microbeads, including the U.S.

Types

Fluorescent polyethylene microspheres are commonly used to run blind tests on laboratory and industrial processes, in order to develop proper methods and minimize cross-contamination of equipment and materials. Microspheres that appear to be invisible in the daylight can be illuminated to display a bright fluorescent response under UV light.

Colored polyethylene microspheres are used for fluid flow visualization to enable observation and characterization of flow of particles in a device. Colored microspheres can also be used as visible markers in microscopy and biotechnology. Sphericity and particle size uniformity create a ball-bearing effect in creams and lotions, resulting in a silky texture and spreadability. Exceptional smoothness and roundness also provides lubrication. Colors add visual appeal to cosmetic products.[5]

Black polyethylene microspheres can have magnetic or conductive functionality, and have uses in electronic devices, EMI shielding and microscopy techniques.

Environmental effects

Microbeads from exfoliating personal care products and toothpastes are washed down the drain, pass unfiltered through the sewage treatment plants and make their way into rivers and canals, resulting in plastic particle water pollution.[6] Plastic microbeads have been found to pollute the Great Lakes in high concentrations, particularly Lake Erie.

Banning production and sale in cosmetics

In 2012, the North Sea Foundation and the Plastic Soup Foundation launched an app that allows Dutch consumers to check whether personal care products contain microbeads.[7] In the summer of 2013, the United Nations Environment Programme and UK based NGO Fauna and Flora International joined the partnership to further develop the app for international audiences. The app has enjoyed success, convincing a number of large multinationals to stop using microbeads,[8] and is available in seven languages. As momentum against microbeads in cosmetics has grown worldwide, companies such as Adidas,[9] The Body Shop, Johnson & Johnson,[10] L’Oréal, Procter & Gamble, and Unilever have pledged to phase out plastic microbeads from their products.[11]

USA

National

At the 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. Representative Frank Pallone proposed the bill in 2014 (H.R. 4895, reintroduced in 2015 as H.R. 1321). On December 7, 2015, his proposal was narrowed by amendment to rinse-off cosmetics, and passed unanimously by the House.[12] The American Chemistry Council and other industry groups supported the final bill,[13][14][15] which the Senate passed on December 18, 2015, and the president signed on December 28, 2015.[12]

States

Illinois became the first U.S. state to enact legislation banning the manufacture and sale of products containing microbeads; the two-part ban goes into effect in 2018 and 2019.[16] The Personal Care Products Council, a trade group for the cosmetics industry, came out in support of the Illinois bill.[17] Other states have followed.

All state bans except California[18] allow biodegradable microbeads. Johnson & Johnson and Procter & Gamble opposed the California law.[19]

In 2014, legislation was voted on but failed to pass in New York.[10]

Local

Erie County, New York has passed the first local ban in the state of New York. It bans the sale and distribution of all plastic microbeads (including biodegradable ones) including from personal care products.[33] Its prohibition on sales is stronger than any other law in the country.[34] It was enacted on August 12, 2015[35] and should take effect in February, 2016. This appears to be the first ban to go into effect in the country. Four other NY counties have followed suit.[36]

The Netherlands

The Netherlands is the first country to announce its intent to be free of microbeads in cosmetics by the end of 2016.[37] State Secretary for Infrastructure and the Environment Mansveld has said she is pleased with the progress made by the members of the Nederlandse Cosmetica Vereniging (NCV), the Dutch trade organisation for producers and importers of cosmetics.[38] All members have ceased using microbeads or are working towards removing microbeads from their product. By 2017 80% of them should have completed the transition to a microbead-free product line. Among the NCV's members are large multinationals such as Unilever, L'Oréal, Colgate-Palmolive, Henkel, and Johnson & Johnson.
