Synthesis of Silica Nanoparticles by Ultrasonic Spray Pyrolysis Technique for Cream Perfume Formulation Development

Abstract

This research focused on silica nanoparticles synthesis by ultrasonic spray
pyrolysis (USP) technique using tetraethylorthosilicate (TEOS) as a precursor. The
synthesized silica nanoparticle was used as a fixative material for cream perfume
formulation. The morphology and structure of synthesized silica nanoparticles were
examined by Scanning Electron Microscope (SEM) technique and X-ray diffraction
technique (XRD), respectively. Adsorption ability of synthesized silica nanoparticle
was also analyzed by incipient wetness impregnation technique. The results showed
that the synthesis temperature of 500°C provided the smallest size of silica
nanoparticle, about 106 nm. The particle size decreased from 347 nm to 106 nm
when the synthesis temperature increased from 300°C to 500°C. Comparing two
types of cream perfume, with and without silica, by applying cream perfume on
glass slide at 37°C for 5 hours, found that odor of cream perfume with silica lasts
longer than cream perfume without silica.
