As the monomer unit, R ³ is preferably a hydrogen atom, and M is preferably a hydrogen atom and / or a sodium atom.

  The ratio of the monomer unit represented by the general formula (1) is 70 to 95 mol% in the acrylic acid polymer, preferably 75 to 90 mol%, and the monomer represented by the general formula (2). The ratio of the unit is 5 to 30 mol% in the acrylic acid polymer, and preferably 10 to 25 mol%. When the proportion of the monomer unit represented by the general formula (1) exceeds 95 mol%, the fingering becomes worse and the smoothness decreases, and when it is less than 70 mol%, the hair repair effect and the moist feeling of the finish are obtained. If the ratio of the monomer unit represented by the general formula (2) is less than 5 mol%, the tackiness occurs, and if it exceeds 30 mol%, the moist feeling of the finish is lowered.

  As long as the effects of the present invention are not impaired, the acrylic acid-based polymer can contain monomer units other than the monomer unit represented by the general formula (1) or (2).

The molecular weight and viscosity can also be controlled by increasing or decreasing the addition amount of a crosslinking agent such as a polyfunctional acrylate. However, if a crosslinking agent is added as much as possible, the molecular weight and the viscosity are rapidly increased, and thus there are aspects that are difficult to control in industrial production. For this reason, it is preferable not to contain a crosslinking agent.

  The acrylic polymer can be obtained in accordance with the method described in JP-A-2007-161986. For example, it can be obtained by mixing monomers that give respective structural units or precursors thereof and copolymerizing them by a method such as solution polymerization, suspension polymerization, emulsion polymerization or the like. In addition, the counter ion in the general formula (2) can be subjected to polymerization by substituting a part or all of it for other than hydrogen ion by a neutralization reaction before polymerization, and neutralized after polymerization or other reaction.
