Glitter is made from plastic and other materials
Glitter is an assortment of flat, small, reflective particles that come in a variety of shapes, sizes, and colours. It is manufactured from a combination of plastic and other materials, such as aluminium, titanium dioxide, iron oxide, and bismuth oxychloride. One of the most common plastics used in glitter is PET plastic, but mica can also be used. These materials are combined into flat, multi-layered sheets, which are then cut into tiny particles.
Modern plastic glitter was first produced in the 1930s by American machinist Henry F. Ruschmann, who invented a machine to cut photo films and paper. Sometimes, the machine would malfunction, generating small pieces of glossy cellulose that employees would use as "snow" for their Christmas trees. Ruschmann also cut mica into washers and glitter from metallized cellulose acetate film. During World War II, when glass glitter became unavailable, Ruschmann found a market for scrap plastics, which were ground into glitter.
Glitter is used in a variety of applications, including cosmetics, clothing, arts and crafts, body paint, and optically variable inks. It is also used in fishing lures to attract prey fish. However, glitter is a significant source of plastic pollution, as it is rarely recycled and can find its way into aquatic habitats, eventually being ingested by animals. It has been estimated that humans ingest or inhale more than 100,000 bits of plastic each day. Glitter can also interfere with the formation of shells and skeletons in marine life, further exacerbating the problem of plastic pollution.
Due to the environmental concerns surrounding plastic glitter, some companies have started to offer biodegradable alternatives. For example, Luminosity Glitter produces eco-friendly glitter from cellulose from wood pulp, primarily eucalyptus. This type of glitter can degrade naturally in environments containing microorganisms, turning into harmless substances such as water, carbon dioxide, and biomass. However, some studies have found that biodegradable glitter may have its own negative impacts, such as hindering the growth of duckweed and phytoplankton.

Plastic glitter is not biodegradable
Modern glitter is usually made from a combination of aluminium and plastic. It is rarely recycled and often ends up in aquatic habitats, where it is ingested by animals. This has led some scientists to call for bans on plastic glitter.
The first production of modern plastic glitter is credited to the American machinist Henry F. Ruschmann, who invented a machine to cut photo films and paper in the 1930s. During World War II, when glass glitter became unavailable, Ruschmann found a market for scrap plastics, which were ground into glitter.
While biodegradable alternatives to plastic glitter are available, there is limited research on their environmental impact. Some studies have found that biodegradable glitter can have similar ecological effects as traditional microplastics, and may even be more damaging to certain types of aquatic life. The term biodegradable is also not strictly regulated, and the eco-friendly claims made by manufacturers may be misleading or false.
To reduce the environmental impact of plastic glitter, individuals can try to avoid purchasing items containing glitter, such as cards, paper, or makeup. However, even with these efforts, it can be difficult to completely prevent glitter from entering the ocean.

Plastic glitter is a microplastic
Modern glitter is usually made from a combination of plastic and aluminium. The first production of modern plastic glitter is credited to the American machinist Henry F. Ruschmann, who invented a machine to cut photo films and paper in the 1930s. The machine sometimes produced small pieces of glossy cellulose, which employees picked up and used as "snow" for their Christmas trees. Ruschmann later cut mica into washers and glitter from metallized cellulose acetate film.
Due to its small size, glitter can easily enter seas and oceans from rivers, via wastewater from homes, and runoff from landfill sites. It is rarely recycled and can find its way into aquatic habitats, eventually being ingested by animals. Glitter can interfere with the formation of shells and skeletons in marine life, which can have a significant impact on reproduction rates, making it more likely for affected organisms to be eaten and less likely to thrive.
Glitter can also attract inorganic and organic chemicals to adhere to them, including polychlorinated biphenyls and toxic heavy metals. The bioaccumulation of these toxins in the food chain poses a big risk to wildlife. In addition, glitter can fragment into even smaller pieces, making the pollution problem worse and more long-lasting.
While biodegradable glitter is available, it may have its own problems. Some researchers have found that cellulose and mica glitter were more damaging to duckweed and phytoplankton growth than conventional glitter. Thus, it is important to conduct ecotoxicological research to test for the impacts of any new types of glitter to avoid creating new problems.

Plastic glitter harms the environment
Modern glitter is usually manufactured from a combination of plastic and aluminium. It is rarely recycled and can find its way into aquatic habitats, eventually being ingested by animals. Glitter is a microplastic, defined as small plastic particles less than 5 millimetres in size. These microplastics can enter the environment directly or come from larger plastic waste that degrades into smaller plastic fragments.
Glitter is used in a wide range of products, from cosmetics and candles to wrapping paper and sunscreen. However, these sparkling flecks don't just disappear when they slough off your face or birthday card. They can enter the environment in various ways, such as through wastewater from our homes or runoff from landfill sites.
The small size of microplastics means they are easily consumed by small marine organisms, which cannot discriminate between particles of food and plastic. Over time, glitter particles fragment into even smaller pieces, making them more easily ingested. They can enter cells and interfere with essential biochemical reactions. This can lead to adverse health effects, as microplastics can carry toxic environmental pollutants, increasing their overall toxicity when ingested.
Glitter also has a negative impact on the environment beyond human health. High concentrations of glitter microplastics can hinder the growth of aquatic organisms like phytoplankton and zooplankton, which play a critical role in oxygen production and carbon dioxide consumption. The ubiquity and minuscule size of glitter make it more dangerous than other microplastics, as it can easily spread and contaminate soil, air, water, and food.
While biodegradable alternatives to traditional glitter are available, there are concerns that they may cause similar damage to the environment. Due to its size, plastic glitter will inevitably make its way into water sources and oceans, where it can be ingested by marine life, impacting their reproduction rates and overall health.

Biodegradable glitter is an alternative
Modern glitter is usually made from a combination of aluminium and plastic. However, biodegradable glitter is an innovative, eco-friendly alternative to traditional glitter. It is made from polylactic acid (PLA) and is derived from plant sources such as wood pulp and eucalyptus. This type of glitter is compostable, reducing environmental pollution, and is safe for use on skin, hair, and nails. It is also non-toxic, vegan, cruelty-free, and fade-resistant.
Biodegradable glitter offers the same sparkle and shine as regular glitter without compromising on quality. It can be used in a variety of applications, including arts and crafts, cosmetics, decor, glasswork, floristry, body art, hair styling, and face makeup. With its high-quality, safe ingredients, and a wide range of colours and sizes, it is a perfect eco-conscious choice for creative projects.
The use of biodegradable glitter can help address the environmental concerns associated with plastic glitter. Plastic glitter, due to its small size, can easily enter and contaminate marine environments, leading to potential ingestion by animals and contributing to the global microplastic problem. Biodegradable glitter, on the other hand, can naturally degrade in environments with microorganisms, turning into harmless substances such as water, carbon dioxide, and biomass.
While biodegradable glitter offers a more sustainable option, it is important to note that some preliminary studies have found that cellulose and mica glitter can be more damaging to duckweed and phytoplankton growth than conventional glitter. Therefore, further ecotoxicological research is needed to fully understand the potential impacts of any new types of glitter and ensure that we are not simply creating new environmental problems.
Overall, biodegradable glitter presents a promising alternative to traditional plastic glitter, allowing individuals to enjoy the sparkle and creativity associated with glitter while also being mindful of the environment and ecological well-being.
