Abstract
Methods, test kits, and compositions for measuring and detecting surfactant concentration in a composition. The method comprises taking a sample of a composition, placing the sample on a substrate, and evaluating the concentration of surfactant in the composition based on appearance of the sample on the substrate. Various substrates can be used to track the spread, distance traveled, and travel time of the sample on the substrate. A substrate is calibrated for use with a particular composition. A mobile application may be used with the substrate to measure the surfactant concentration.
Claims36
A method of measuring a concentration of a surfactant in a composition, the method comprising:
- depositing a quantity of a sample of the composition on a target region on a substrate made of a material;
- obtaining an image of the sample on the target region of the substrate, and processing the image to determine a percentage fill of the target region;
- and
- inputting the percentage fill of the target region into an algorithm based upon the material, the surfactant, and the composition to determine the concentration of the surfactant.
