  [Problem] To provide a dust reducer which suppresses blocking against moisture absorption and has a reduced amount of dust generation, without impairing the water absorption physical properties that are required from a water absorbing agent, such as water absorption capacity under load; a method for producing a water absorbing agent using the dust reducer; and a water absorbing agent in which blocking against moisture absorption is suppressed and which has a reduced amount of dust generation. [Solution] A dust reducer for a water absorbing agent containing a surface crosslinked polyacrylic acid (salt)-based water absorbent resin as a main component, wherein the dust reducer is a multi-component metal compound which has a hydrotalcite structure and contains a hydroxyl group and two kinds of metal cations that are divalent and trivalent.

  Provided is a water absorbent resin having excellent liquid permeability, water absorbent speed, anti-impact stability, and weather resistance. Provided is a polyacrylic acid (salt)-based water absorbent resin powder in which the water absorption capacity without load (CRC) is 30 to 45 [g/g], the water absorption capacity under load (AAP 0.3) is 20 to 35 [g/g], the water absorption capacity under load (AAP 0.7) is 10 to 28 [g/g], and the weight average particle diameter (D50) is 300 to 500 μm, characterized by including p-methoxyphenol; having a degradable soluble component (0.05% L-A (saline) for 2 hours/60° C., one hour extraction rinse/room temperature) of 40% by weight or less; and having a internal gas bubbles ratio of 0.1 to 2.5%, as specified by the following equation. (Internal gas bubbles ratio)[%]=(True density)−(Apparent density)}/(True density)×100
