Fifth generation flame retardants are a class of chemicals that are designed to be more effective and safer than earlier generations of flame retardants. These chemicals are typically used in products that are at risk of catching fire, such as electronics, furniture, and building materials.

Fifth generation flame retardants are designed to be more environmentally friendly and less toxic than earlier generations, which have been linked to health and environmental problems. They are also designed to be more effective at preventing fires, while at the same time being less likely to leach out of products and contaminate the environment.

Some examples of fifth generation flame retardants include phosphorus-based compounds, which work by disrupting the chemical reactions that lead to combustion, and nitrogen-based compounds, which work by releasing gases that help to dilute the oxygen in the air and prevent flames from spreading.
