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 (R2) of 0.998.
如今，初榨椰子油（VCO）正成为一种有价值的油，因其多种生物活性而受到研究人员的关注。在化妆品行业，VCO是一种出色的材料，可作为皮肤保湿剂和柔软剂。因此，开发一种提供快速可靠技术的定量分析方法很重要。采用衰减全反射（ATR）样品处理技术的傅里叶变换红外（FTIR）光谱可成功用于定量分析乳膏化妆品制剂中的VCO。使用偏最小二乘（PLS）模型校准的多元分析表明，VCO的实际值与FTIR预测值之间具有良好的关系，决定系数（R2）为0.998。
