Polyethyleneimine (PEI), a versatile polymer known for its cationic properties and diverse applications, finds extensive use in sectors such as water treatment, detergents, cosmetics, Paper, and coatings. In water treatment, PEI-based polymers function as flocculants or coagulants, facilitating the removal of contaminants such as heavy metals, organic pollutants, and dyes from water sources. PEI provides adhesion to various substrates (e.g., metals, plastics) due to its strong bonding capabilities and PEI coatings provide protection against corrosion, abrasion, and chemical damage. In cosmetics it primarily acts as a binding agent, helping to stabilize formulations and improve the consistency and texture of cosmetic products such as creams, lotions, and gels.
