Pengaruh Kecepatan Homegenisasi Terhadap Sifat Fisika dan Kimia Krim Nanopartikel dengan Metode High Speed Homogenization (HSH)

Abstract

Nanoparticle cream is the development of nanotechnology in cosmetics fields for improving the function of cream. High speed homogenization (HSH) is one of the methods for creating nanoparticle cream. In this research, the use of natural materials based palm oil derivative such as stearic acid, cetil alcohol, cetil stearil alcohol was chosen in nanoparticle cream producing by using HSH methods.The speed variable of homogenization of 1000 rpm, 1500 rpm, 2,000 rpm and 2,500 rpm intended to find out the influence of speed toward the properties of cream product. The observation result showed the influence on physical display in term of texture but not in homogeneity , stability and cream color. The pH of the product during two months storage for all variables were still stable. The particle size was increased in the homogeneity of speed at 2000 rpm and 2500 rpm. In this research has produced the cream in particle size from 239.86 to 358.10 nm which enter in nanoparticle category 50 nm to 1000 nm. The stability of nanoparticle cream product in the range of 97,20 to 98%.
