New Method for Determination of Solid Fat Content in Cosmetic Products by SFC NMR
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 2
Abstract
A new analytical NMR method for the determination of Solid Fat Content (SFC) in cosmetic formulations e.g. Kajal and lip balms, which are based on natural waxes and vegetable oils composition. By using NMR technique solid fat content in the formulations quantified easily. The traditional method for measuring SFC has been dilatometry but this is regarded as slow, inaccurate and cumbersome. However, low resolution Nuclear Magnetic Resonance (NMR) has been the method of choice for the determination of SFC. The method based on direct measurement of the NMR signal from the solid and liquid fat. The method performed in the temperature between 0 ̊C to 60 ̊C, the results are good reproducible and accurate. The method is more consistent and reduced the cost of analysis.
