Abstract: A method of evaluating fatigue in a hair fibre sample includes receiving fatigue testing data for the hair fibre sample for a plurality of loading cycles, in which the fatigue testing data comprises force or stress against displacement or strain data. The method also includes determining, for at least a subset of the loading cycles, a loading energy based on data from the fatigue testing data. The method also includes determining an indication of fatigue in the hair fibre sample based on the loading energy of the at least a subset of the loading cycles.

Abstract: Disclosed is a benefit agent delivery particle comprising a benefit agent; and a chitosan salt at the outer surface of the particle, wherein the chitosan salt comprises a chitosan component and amino acid anion, wherein the amino acid comprises phenylalamine; the amino acid does not comprises tyrosine; and the amino acid does not comprises histidine or the amino acid comprises no greater than 20% of histidine by mole of the total amino acid, wherein the benefit agent comprises fragrance, pro-fragrance, hair conditioning agent, anti-dandruff agent, moisturizers, emollients, dyes, pigments, color care additives, or a mixture thereof.

Abstract: A method for identifying a stain on a textile (10), the method comprising the steps of: performing near-infrared reflectance spectroscopy to obtain spectral data from the stain over a range of wavelengths ranging from a shortest wavelength to a longest wavelength, the shortest wavelength having a value of 1595 nm or longer; accessing reference spectral data (33) of known stains; and comparing the spectral data of the stain to the reference spectral data of known stains to identify the stain.
