Superglue, or ethyl 2-cyanoacrylate, is a synthetic polymer that is generally considered to be vegan-friendly as it does not contain animal products. However, its production on an industrial scale is likely harmful to the environment. Traditional superglues are made from fossil fuels and can take thousands of years to biodegrade. The production of 1 tonne of epoxy creates an estimated 5.8 tonnes of carbon dioxide.

What You'll Learn
Super glue is made from synthetic polymers
Superglue, or ethyl 2-cyanoacrylate, is a synthetic polymer that was discovered in 1951. It is a complex molecule made up of smaller, simpler molecules (monomers) that attach to form repeating structural units. Once a polymeric reaction has been catalysed, it can be difficult to halt. The natural impulse to form polymeric chains is very strong, as are the resulting molecular bonds.
The initial ingredient in super glue, ethyl cyanoacetate, is placed into a kettle with revolving blades and mixed with formaldehyde. The mixing triggers condensation, a chemical reaction that produces water; this water is then evaporated as the kettle is heated. When the water has evaporated, what remains in the kettle is the C.A. polymer. Next, the kettle is heated again, causing thermal cracking of the polymer and creating reactive monomers that separate out. When the finished glue is applied, these monomers recombine to form a bond.
Cyanoacrylate glues are mainly used as adhesives. Thin layers bond most effectively, with thick layers being much less effective. They can bond many substances, including human skin and tissues, natural fibres, cotton, wool, and leather. Their effectiveness in bonding metal and general versatility have made them popular among modelling and miniatures hobbyists.
Standard superglue is 100% ethyl 2-cyanoacrylate, but many custom formulations are used for specific applications. Some rock climbers use cyanoacrylate to repair damage to the skin on their fingertips, and stringed-instrument players can form protective finger caps. In industry, C.A.s have become important in construction, medicine, and dentistry.
Traditional superglues are generally made from fossil fuels and take thousands of years to biodegrade. Their production also generates a large amount of greenhouse gas emissions. However, a new alternative derived from soya plants has been found to bond metal, wood, and synthetic surfaces just as strongly.

Cyanoacrylate is the main ingredient
Cyanoacrylate glues are incredibly versatile and are used in a wide range of applications, from simple household repairs to industrial uses in construction, medicine, and dentistry. They are also used in the cosmetology and beauty industry as eyelash extension glue and for certain artificial nail enhancements. Additionally, their effectiveness in bonding metal has made them popular among hobbyists, such as those who build model aircraft or work with marine aquariums.
The versatility and strength of cyanoacrylate adhesives come at an environmental cost, however. The production of traditional superglues generates a large amount of greenhouse gas emissions, and the adhesives themselves take thousands of years to biodegrade. This has spurred the development of more sustainable alternatives, such as soy-based glues, which can be just as strong as traditional superglues while offering the added benefit of biodegradability.
While the exact details of the industrial-scale processes used to create cyanoacrylate adhesives may remain unknown, the environmental impact of these processes is undeniable. With the continued development of more sustainable alternatives, there is hope that the environmental footprint of adhesives can be reduced, offering a more eco-friendly way to stick things together without compromising on strength.

Fossil fuels are used to make toluene, a solvent in some glues
Traditional superglues are generally made from fossil fuels, which take thousands of years to biodegrade. Fossil fuels are used to make toluene, a solvent in some glues. Toluene is a liquid hydrocarbon that is often used as a solvent in glue. Glue is a gelatinous adhesive substance used to form a surface attachment between discrete materials. Solvent glues are made by mixing an adhesive base with a chemical solvent that aids in spreading the glue; the glue dries as the solvent evaporates. Most solvents are flammable and evaporate quickly.
The production of traditional superglues generates a large amount of greenhouse gas emissions. For example, producing one tonne of epoxy creates an estimated 5.8 tonnes of carbon dioxide. As a result, there is a growing interest in developing biodegradable alternatives to traditional superglues.
One potential alternative is soy-based glue, which can cut carbon emissions. The plants used to make this type of glue absorb carbon dioxide, potentially reducing the environmental impact of glue production. While soy-based glue shows promise, it may not be suitable for all applications, such as gluing together automotive and aerospace structures.
Another approach to reducing the environmental impact of glue production is to use recycling to produce acetone, a common ingredient in nail varnish removers and paint removers. By using recycled materials and alternative sources of adhesive, it may be possible to reduce the overall environmental impact of glue production and usage.

A soy-based alternative is stronger and biodegradable
Traditional superglues are generally made from fossil fuels, and they can take thousands of years to biodegrade. Their production also generates a large amount of greenhouse gas emissions. However, a soy-based alternative to superglue is not only stronger but also biodegradable.
Soy-based glue is made by extracting oil from soybeans and blending it with other natural ingredients, such as vegetable oils, waxes, resins, and natural polymers. It is a safe, eco-friendly, and versatile alternative to traditional glues. The soybeans used to make this glue are a renewable and sustainable resource.
The soy-based adhesive has been tested on wood, plastics, and metals, and the results have been impressive. In many cases, it has proven to be just as strong, if not stronger, than traditional superglues. For instance, it was found to be around 30% stronger than superglue when bonding polished aluminum. These adhesive properties were even maintained when the glue was submerged in water. After 24 hours underwater, the soy glue retained 75-100% of its initial bond strength.
The soy-based glue can be used in various industries and everyday applications. It can be used in woodworking, paper and packaging, textiles, automotive, and construction. Its strong bonding capabilities make it suitable for bonding wood, paper, fabric, and other materials.
The soy-based alternative to superglue offers a more sustainable option that is also stronger and biodegradable. With its impressive adhesive properties and versatility, it could potentially replace traditional superglues and contribute to a greener planet.

Super glue is generally considered vegan
Superglue, also known as cyanoacrylate, is generally considered vegan. This is because it does not contain any animal products or ingredients derived from animals. Instead, super glue is made from synthetic polymers, specifically cyanoacrylates, which are sourced from petroleum, or fossil fuels.
The production of super glue involves placing ethyl cyanoacetate into a kettle with revolving blades and mixing it with formaldehyde. This triggers a chemical reaction that produces water, which is then evaporated as the kettle is heated. The remaining substance in the kettle is a polymer, which is heated again to create reactive monomers that separate out and form bonds when the glue is applied.
While super glue does not contain animal products, the industrial-scale processes required to create it are likely harmful to the environment. The production of adhesives made from fossil fuels generates a large amount of greenhouse gas emissions, with approximately 5.8 tonnes of carbon dioxide produced for every tonne of epoxy. These adhesives also take thousands of years to biodegrade, contributing to the accumulation of microplastics in the environment.
However, there are efforts to develop more sustainable alternatives to traditional super glues. For example, a new adhesive derived from soya bean oil forms high-strength bonds that can later dissolve, offering a biodegradable option for commercial products, packaging, and sticky labels. This soy-based glue has been found to be just as strong, if not stronger, than traditional super glues when bonding certain materials, such as polished aluminium. It also maintains its adhesive properties when submerged in water, retaining 75-100% of its initial bond strength after 24 hours underwater.
