2. Description of the Related Art Hitherto, ionic surfactants such as anionic surfactants and amphoteric surfactants have been used to improve the rinsing and finishing properties of detergent compositions. High molecular substances and oils are added. However, many of these components are difficult to dissolve in the surfactant, and the dispersion system is frequently used in order to easily form the foam and satisfy the finish. Moreover,
At present, the viscosity of the composition is increased for the purpose of dispersing oil and the like, and the stability is secured. For this reason, these compositions are liable to cause problems such as an unnecessarily high viscosity during actual use, and when filled in a bottle, not only are the discharge properties inferior, but also the spread to the object to be cleaned during use is not good. Have the following problems.
