By the way, it is known that polyacrylic acid amide is used as a stabilizer, an emulsifier, a thickener, etc., The present inventors also developed the multimodal hair treatment agent which mix | blended polyacrylamide with the 2nd agent used after a 1st agent. I was going. During the development, when the second agent is applied to the hair to which the first agent is applied, particles that can be seen with the naked eye may occur. Since these particles give a bad impression to 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 precipitation of the particles.

In view of the above circumstances, when the second agent of the polyacrylic acid amide formulation is applied after the first agent is applied, the present invention provides a multi-component hair treatment agent capable of inhibiting particle precipitation or suppressing the degree of particle precipitation. It is for the purpose of providing.

MEANS TO SOLVE THE PROBLEM The present inventors acquired the knowledge that particle | grains generate | occur | produce when a 2nd agent is apply | coated, if the 1st agent applied to hair is mix | blended with the quaternary ammonium salt before the 2nd agent of polyacrylamide mix | blending. Moreover, the degree of particle formation discovered that it can suppress by further mix | blending hydrophobization hydroxypropylmethylcellulose with a 2nd agent, and came to complete this invention.

That is, the multi-hair type hair treatment agent which concerns on this invention is provided with the 1st agent and the 2nd agent apply | coated to the hair after apply | coating the said 1st agent, The said 1st agent mix | blended quaternary ammonium salt (I) The second agent is a mixture of hydrophobized hydroxypropylmethylcellulose and polyacrylic acid amide.

As for the compounding density | concentration of the quaternary ammonium salt (I) in the said 1st agent, 7.0 mass% or less is preferable. The particle | grains which generate | occur | produce when apply | coating the said 2nd agent generate | occur | produce with a quaternary ammonium salt (I) and polyacrylamide, The particle | grains precipitate as the compounding density | concentration of the quaternary ammonium salt (I) in the said 1st agent decreases. Since the degree of can be suppressed, 7.0 mass% or less is preferable.

As for the compounding density | concentration of the quaternary ammonium salt (II) in the said 2nd agent, 1.0 mass% or less (including no mix | blending) is preferable. Since the coexistence of polyacrylic acid amide and 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 less the degree of particle precipitation can be suppressed. , 1.0 mass% or less (including no blending) is preferable.

The compounding concentration of the hydrophobized hydroxypropyl methyl cellulose in the second agent is, for example, 1.0 mass% or less.

As for the compounding density | concentration of the polyacrylic acid amide in the said 2nd agent, 3.0 mass% or less is good. It is easy to apply | coat a said 2nd agent by hand in this compounding density | concentration.

According to the multi-part hair treatment agent of the present invention, since the hydrophobized hydroxypropyl methyl cellulose is blended with the second agent together with the polyacrylic acid amide, even if the quaternary ammonium salt (I) is blended with the first agent, the second agent is coated. The degree of particle precipitation due to this can be suppressed.

The present invention will be described below based on the multi-form hair treatment agent of the present embodiment.
