Quantitative analysis of virgin coconut oil in cream cosmetics preparations using fourier transform infrared [FTIR] spectroscopy

ABSTRACT

Today, virgin coconut oil [VCO] is becoming valuable oil and is receiving an attractive topic for researchers because of its several biological activities. In cosmetics industry, VCO is excellent material which functions as a skin moisturizer and softener. Therefore, it is important to develop a quantitative analytical method offering a fast and reliable technique. Fourier transform infrared [FTIR] spectroscopy with sample handling technique of attenuated total reflectance [ATR] can be successfully used to analyze VCO quantitatively in cream cosmetic preparations. A multivariate analysis using calibration of partial least square [PLS] model revealed the good relationship between actual value and FTIR-predicted value of VCO with coefficient of determination [R[2]] of 0.998
