Çift Katmanlı Hidroksitlerin Kozmetikte Uygulamaları

Abstract

Since ancient Egypt cosmetics have been a part of our life. Cosmetic products appeal to a large variety of areas ranging from perfume, hair dyes and care products, toothpastes, dermal care products, face-eye make-up materials. Cosmetic products contain biological active components. These active compounds generally are sensitive to parameters such as light, pH, temperature and air oxidation and they are not stable. This also causes unwanted possibilities such as degradation of cosmetic products. Layered double hydroxides (LDHs), which are two-dimensional (2D) nanostructures, due to their extraordinary physicochemical properties may be a good alternative for to overcome these drawbacks. LDHs have found wide application areas such as removal of heavy metals, radio nucleotides, organic pollutants, oil pollution, hydrogen production and they are used in super capacitors, cells, solar cells, catalysis and in biomaterials for environmental, energy and catalysis. Moreover, nanostructured LDHs have been used as successful carriers for cosmetic products due to their wide surface areas, expandable interlayers that can host active molecules, biocompatibility, high water retention capacity, high swelling ability and cost-effectiveness. This study provides good practices of LDHs in cosmetics for UV protection, skin care and antimicrobial properties.
