Those in the range of g (polymer weight) are preferred. If the water absorption is less than 130 g / g, the feel may be hard even when absorbing water. If it exceeds 1000 g / g, when water is added to the particulate skin cleansing agent, the superabsorbent polymer may absorb too much water, and may not give an essence-like feel. In this region, an essence-like appearance is formed and the feel is improved even when factors that affect the water absorption ratio such as a surfactant are taken into consideration. In the present invention, the water absorption refers to the case where the amount of a sample is 0.1 g in 100 g of ion-exchanged water at 25 ° C.
2 g was added without stirring, and after 10 minutes, the value was measured by filtering through an 80-mesh nylon mesh, draining for 10 minutes, and weighing 5 times (converted to water absorption per 1 g).

Further, the gel strength of the superabsorbent polymer is 0.3.
Those having a range of 10 × 1000 to 0.35 × 1000 N / m ² are preferable. Within this range, the feel when water is added is excellent. The gel strength referred to here is a value measured using a card meter (CURDMETER MAX type) manufactured by Iio Electric. 0.6 g of a sample was added to 60 g of ion-exchanged water while stirring with a magnetic stirrer to prepare a 100-fold gel, which was left in an incubator at 30 ° C. for 8 hours, and the gel strength was measured using the above card meter.
