Biocides candidate

Contraction in the number of EPA-allowed biocides has heightened efforts to develop naturally derived preservatives and microorganisms capable of countering microbial degradation. Neem oil A. dirachta indica seed extract) has been featured as an exceptional natural candidate for the preservation of cosmetic products. Naturally derived chemicals with antimicrobial properties have been used since antiquity as preservatives. However, displacement of successhil synthetic products by natural products in preservatives of any category remains to be witnessed. 

CS-metal/alumina complexed nanocomposites could be promising candidates for antimicrobial agents in the cosmetic, food and textile industries. Quaternised CS and CS-iodine could be future materials with enhanced biocidal properties. Improving our understanding of antimicrobial mechanisms will enable the continued design of new biocidal polymers, which is necessary in order to combat the development of microbial resistance. 

In contrast to the conventional solvent-based paints using toxic biocides, the water-based sol-gel paint does not contain harmful substances and is simply and efficiently applied at room temperature, requiring neither curing nor pretreatment coat for bonding to a variety of substrata, while the painted surfaces are uniform, uncracked, and topographically smooth, which make them viable AF/FR candidates for specialized applications on surfaces involved in optics, sensors, solar panels, and related applications (Figure 34.4).
