摘要研究了近红外反射分析光谱法用于原材料洗涤剂和间歇工艺洗发水质量保证的适用性。通过活性洗涤剂、固体、水分、苯甲酸、pH和粘度的主要分析技术分析了阳离子表面活性剂月桂基硫酸铵和月桂基硫酸钠。分析两种品牌的洗发水的活性洗涤剂、固体和水分。所有这些都在1100 nm至2500 nm的近红外范围内进行扫描，以建立预测方程。结果表明，所有的化学成分研究可以预测的近红外。与湿化学法或圣安达尔仪器法相比，该方法的优点包括无需样品制备，分析时间少于1分钟。
Synopsis The suitability of near infrared reflectance analysis spectroscopy for the quality assurance of raw material detergents and batch process shampoos has been investigated. The artionic surfactants, ammonium lauryl sulfate and sodium lauryl sulfate, were analyzed by primary analytical techniques for active detergent, solids, moisture, benzoic acid, pH, and viscosity. Two brands of shampoo were analyzed for active detergent, solids and moisture. All were scanned in the near infrared from 1100 nm to 2500 nm to develop prediction equations. The results indicate that all of the chemical constituents investigated can be predicted by near infrared. The advantages of this procedure over wet chemical or st.andard instrumental methods include no sample preparation and analysis time of less then one minute.
