A simple method to prepare a hybrid material (ZnAl–AgNPs) based on silver nanoparticles and ZnAl layered double hydroxides (ZnAl LDHs), for possible use in a cosmetic formulation as deodorant, was reported. ZnAl– AgNPs, include the high adsorption capacity, the biocompatibility, the antacid properties of LDH and the antibacterial activity of AgNPs. According to the characterization with X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), itwas possible to confirm that interaction of AgNPs with ZnAl LDH occurs by adsorption rather than intercalation of AgNPs in LDH. The deodorant activity of ZnAl– AgNPs was tested using the headspace solid phase micro-extraction gas chromatography (HS-SPME-GC) and the antibacterial property was monitored on gram-negative bacteria.

Abstract
A simple method to prepare a hybrid material (ZnAl–AgNPs) based on silver nanoparticles and ZnAl layered double hydroxides (ZnAl LDHs), for possible use in a cosmetic formulation as deodorant, was reported. ZnAl– AgNPs, include the high adsorption capacity, the biocompatibility, the antacid properties of LDH and the antibacterial activity of AgNPs. According to the characterization with X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), itwas possible to confirm that interaction of AgNPs with ZnAl LDH occurs by adsorption rather than intercalation of AgNPs in LDH. The deodorant activity of ZnAl– AgNPs was tested using the headspace solid phase micro-extraction gas chromatography (HS-SPME-GC) and the antibacterial property was monitored on gram-negative bacteria. For comparison raw ZnAl LDH was also investigated. The results showed that both raw ZnAl LDH and ZnAl–AgNPs have deodorant activity higher than that of zinc ricinoleate, normally used in commercial formulations. ©I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
