Problems solved by technology

This patented composition mainly improves the dyeing property and touch after use by adding polysiloxane. Although the content of the dye is defined as 0.001-0.1 wt% in the claims, it is only aimed at the content of the dye in the examples. The dyeing test was carried out for the composition of 0.6 wt%, and the dyeing test was not carried out for the claimed dye content range of 0.001-0.1 wt%. Therefore, the composition of this patent can only prove that it has a better touch. For It is difficult to judge the dyeing property of the composition with 0.001-0.1 wt% dye
