They can also be incorporated into formulations designed to prevent the spread of bacterial infections in plants. These applications help ensure higher crop yields and reduce the need for chemical pesticides, promoting more sustainable farming practices.

Moreover, hydantoin-based compounds are being explored for their potential in protecting plants against environmental stressors, such as extreme temperatures or drought conditions, by enhancing plant resistance and improving overall resilience. This opens new avenues for research into hydantoin as a bioregulator in agriculture, promoting healthier crops with fewer chemical inputs.

4. Water Treatment and Environmental Applications
Hydantoin derivatives have also found applications in environmental engineering, particularly in water treatment processes. Certain hydantoin-based compounds have been used as agents in the removal of heavy metals and other pollutants from water, making them valuable for industrial wastewater treatment. Their ability to interact with metals and other contaminants allows hydantoin derivatives to act as chelating agents, binding to pollutants and facilitating their removal.

In addition, hydantoin’s antimicrobial properties make it suitable for use in water purification systems. By inhibiting the growth of harmful microorganisms in water systems, hydantoin-based compounds can help maintain the cleanliness and safety of industrial water supplies. This application is particularly relevant in industries that require high levels of water purity, such as pharmaceuticals, food processing, and electronics manufacturing.

Hydantoin derivatives can also be employed in environmental cleanup efforts, such as in the remediation of contaminated soils or the removal of toxic substances from industrial sites. Their use as environmental biocides can help reduce the environmental impact of industrial operations and support sustainability efforts.

5. Lubricants and Additives
Hydantoin compounds are used in the formulation of industrial lubricants and additives due to their ability to improve the stability and performance of lubricants under extreme conditions. The nitrogen-containing structure of hydantoin enhances the lubricating properties of oils and greases, reducing wear and tear on mechanical components. This makes hydantoin-based lubricants particularly valuable in high-performance applications such as automotive engines, industrial machinery, and aerospace technology.

Hydantoin derivatives can also function as antioxidants, preventing the degradation of lubricants due to exposure to heat and oxygen. This improves the longevity of machinery and reduces the frequency of maintenance, which is essential in industries where downtime can be costly.

6. Cosmetic and Personal Care Products
In the cosmetic industry, hydantoin derivatives are used for their stabilizing and moisturizing properties. Hydantoin, particularly in the form of hydantoin derivatives like imidazolidinyl urea, is commonly found in cosmetic formulations as a preservative. It helps extend the shelf life of personal care products by preventing the growth of harmful microorganisms, such as bacteria and fungi.

Additionally, hydantoin is valued for its ability to act as a humectant, attracting and retaining moisture in the skin. This makes it a useful ingredient in skin creams, lotions, shampoos, and other personal care products aimed at maintaining hydration and improving skin health.
