Description
Summary:	To improve the detergency of mud stains without triphosphate, we developed a new composition that enhances the detergency of mud stains more efficiently. To develop the composition, a new correction method based on the probability density functional method was used to compare the results of approximately 100 cleaning tests conducted on different days using various active ingredients. As a result of various evaluations, it was found that the combination of a homopolymer with a molecular weight of approximately 2000 and a chelating agent can effectively improve the detergency of particle stains. By combining washing experiments with different polymer concentrations, water hardness, turbidity, and reduced viscosity, we were able to estimate the expansion of the polymer and the washing mechanism using a combination of low-molecular-weight polymers and chelating agents.
