%X In this work was studied the applicabilty of the near infrared reflectance spectroscopy (NIRS) to determine the sodium dodecylbenzene sulfonate in ten types of liquid cleaners. To obtain the calibration curve was applied partial least squares regression, due to the presence of the spectral interferences. Was confirmed the presence of matrix effect. The method has acceptable trueness and precision. Was found a expanded uncertainty of (0,0538), it is less than the required uncertainty (0,1708) indicating that the NIRS method can be applicable for determining sodium dodecylbenzene sulfonate in liquid cleaners
