    Abstract:
    Clariant Tarragona has a quality control department that seeks to increase production efficiency without compromising sustainability or safety. To this end, it employs near-infrared (NIR) spectroscopy, which yields rapid, reliable results with less waste and without altering the sample. This study developed new NIR methods to determine the hydroxyl value and saponification value (mg KOH/g) in fatty alcohol ethoxylation derivatives (using ethylene oxide), employing a multivariate calibration technique based on Partial Least Squares (PLS).
