Abstract: The present invention relates to a method for product identification comprising subjecting a sample to cyclic voltammetry, wherein the sample is subjected to a plurality of voltammetric cycles to obtain a data set for each cycle and wherein the data sets comprise data points; and comparing the data set for each cycle with a data set for a corresponding cycle of at least one known product to determine whether the sample is the known product. The present invention further relates to a method for determining a profile for a known product, which may be used in determining the identity of a sample.

Abstract: A method for the quality control of a cosmetic composition changing its electromagnetic spectral properties under application conditions from an initial state to an end state. The composition is subjected to a measurement condition under which the change of electromagnetic spectral properties occurs over time, the change of electromagnetic spectral properties is measured at least at two different points in time, where the electromagnetic spectral properties at an earlier point in time are different from the electromagnetic spectral properties at the later point in time and at least one value of a parameter derivable from the measured change of electromagnetic spectral properties is determined and compared to a control value of the same parameter.

Abstract: The present invention relates to a method of inhibiting the growth of microorganisms in a metal working fluid comprising adding to the metal working fluid a benzisothiazolin-3-one of the Formula (1): wherein R is C4-5-alkyl; R1 is hydroxy, halogen (especially chlorine), C1-4-alkyl or C1-4-alkoxy; and n is from 0 to 4.
