PROBLEM TO BE SOLVED: To obtain various textures with good cosmetic properties, easily dissolve or disperse in water, have reproducible gel property between batches, adapt to a wide range of pH, and It provides a product that is stable over time at room temperature or higher, is soft and slippery when applied, is stable upon storage, is homogeneous, non-flowable and difficult to flow. Triblock structure B-A-B (where A is an ionic water-soluble polymer block, B is a hydrophobic polymer block, and the amount of polymer block A is the total weight of the triblock polymer) At least one water-soluble or water-dispersible polymer.
