It is known that polyacrylic acid amide is used as a stabilizer, emulsifier, thickener or the like. The present inventors have also developed a multi-component hair treatment agent containing a polyacrylic acid amide in a second agent to be used after the first agent I was in progress. During the above development, if the second agent is applied to the hair coated with the first agent, particles that can be visually recognized may be generated. Since these particles impose a bad impression on the feeling of use of the multi-component hair treatment agent, it is required to prevent the precipitation of the particles or to suppress the degree of particle precipitation.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a multi-component hair treatment agent capable of inhibiting the precipitation of particles or suppressing the degree of particle precipitation when the second agent of polyacrylamide amide compounding is applied after coating the first agent .

The inventors of the present invention have obtained the knowledge that, when the first agent to be applied to the hair is a quaternary ammonium salt prior to the addition of the polyacrylamide amide compound, particles are generated when the second agent is applied. Further, it has been found that the degree of particle formation can be suppressed by further adding hydrophobic hydroxypropylmethylcellulose to the second agent, and the present invention has been accomplished.

That is, the multifunctional hair treatment agent according to the present invention comprises a first agent and a second agent applied to the hair after the first agent is applied, wherein the first agent is a compound containing (I) a quaternary ammonium salt , And the second agent is a combination of hydrophobic hydroxypropyl methylcellulose and polyacrylic acid amide.

The compounding concentration of the quaternary ammonium salt (I) in the first agent is preferably 7.0 mass% or less. The particles formed when the second agent is applied are generated by the quaternary ammonium salt (I) and the polyacrylic acid amide, and the compounding concentration of the quaternary ammonium salt (I) in the first agent is, , It is preferable to be 7.0 mass% or less.

The compounding concentration of the quaternary ammonium salt (II) in the second agent is preferably 1.0% by mass or less (including no compounding). Since the coexistence of the polyacrylamide and the quaternary ammonium salt in the same phase causes particle precipitation, the lower the compounding concentration of the quaternary ammonium salt (II) in the second agent, the more the degree of particle precipitation can be suppressed , And 1.0% by mass or less (including no compounding).

The compounding concentration of hydrophobicized hydroxypropylmethylcellulose in the second agent is, for example, 1.0% by mass or less.

The compounding concentration of the polyacrylic acid amide in the second agent is preferably 3.0 mass% or less. If this concentration is used, it is easy to spread the second agent by hand.

According to the multi-component hair treatment agent of the present invention, hydroxypropyl methylcellulose hydrophobized together with polyacrylic acid amide is blended with the second agent, so that even when the quaternary ammonium salt (I) is blended in the first agent, Can be suppressed.
