(Wherein R ³ represents a hydrogen atom or a methyl group, M represents a hydrogen atom, an alkali metal atom, ammonium or an amine)

Examples of the alkali metal atoms include sodium atoms, potassium atoms, and amines, such as monoethanolamine, diethanolamine, and triethanolamine. Further, when M is an alkali metal atom, ammonium or amine, -COOM forms a salt. do.

As a monomer unit represented by General formula (1), it is preferable that R <^1> is a hydrogen atom, R <^2> is a hydrogen atom, and A is -NH-, and as a monomer unit represented by following General formula (2), R <^3> is It is preferable that a hydrogen atom and M are a hydrogen atom and / or a sodium atom.

The ratio of the monomer unit represented by General formula (1) is 70-95 mol% in acrylic acid type polymer (in 100 mol% of all monomer units), 75-90 mol% is preferable, and is represented by General formula (2) The ratio of the monomeric unit used becomes 5-30 mol% (in 100 mol% of all monomeric units) in an acrylic acid polymer, and 10-25 mol% is preferable. When the ratio of the monomeric unit represented by General formula (1) exceeds 95 mol%, the hair combing will worsen, for example, the hair smoothness will fall, and if it is less than 70 mol%, the combing of a finger will worsen. This lowers and storage stability also worsens.

The acrylic acid polymer may contain monomer units other than the monomer units represented by the general formula (1) or (2) as long as the effects of the present invention are not impaired. As another monomer unit, nonionic monomers other than the monomer unit represented by General formula (1) or (2), an amphoteric monomer, a semipolar monomer, a cationic monomer, and polysiloxane group containing are contained, for example. The monomer unit corresponded to a monomer is mentioned. As for the ratio of monomer units other than the monomer unit represented by General formula (1) or (2), 0-25 mol% is preferable in an acrylic acid polymer.

The weight average molecular weight of the acrylic acid polymer is preferably 3,000 to 100,000. If it is less than 3,000, there may be a lack of brittleness of hair, the smoothness and conditioning effect of hair, and if it exceeds 100,000, the ease of application may deteriorate. It is more preferably set to 10,000 to 30,000, more preferably 10,000 to 20,000, and even more preferably 12,000 to 17,000 in order to increase the smoothness of the hair without the brittleness of the hair, the ease of applying the agent and the smoothness of the hair.

The weight average molecular weight can be measured by gel permission chromatography, and specifically, the apparatus: Tosoh Corporation, SC8010, SD8022, RI8020, CO8011, PS8010, Column: Wako Pure Chemical Industries, Ltd. Wakopak (Wakobeads G-50), development Solvent: Water / methanol / acetic acid / sodium acetate = 6/4 / 0.3 / 0.41 (volume ratio)) can be obtained using polyethylene glycol as a standard.

Adjustment of the molecular weight of an acrylic acid polymer can be performed by controlling the polymerization degree of a polymer, for example. Moreover, molecular weight and viscosity can also be controlled by increasing or decreasing the addition amount of crosslinking agents, such as polyfunctional acrylate. However, when a crosslinking agent is added more than a little, molecular weight and a viscosity may increase rapidly, and there exist some aspects which are difficult to control in industrial manufacture. For this reason, it is preferable that a crosslinking agent is not included.

An acrylic acid polymer can be obtained based on the method of Unexamined-Japanese-Patent No. 2007-161986. For example, it can obtain by mixing the monomer which gives each structural unit or its precursor, and copolymerizing by methods, such as solution polymerization, suspension polymerization, and emulsion polymerization. In addition, the counter-ion in General formula (2) can also be provided to superposition | polymerization by changing one part or all to a thing other than hydrogen ion by neutralization reaction before superposition | polymerization, and after superposition | polymerization or other reaction, Some or all of them may be replaced with other than hydrogen ions. These can be selected and performed appropriately by the convenience of the synthesis. It is preferable to perform a polymerization reaction in hydrophilic solvents, such as ethanol, and well-known polymerization initiators, such as dimethyl 2,2'- azobis (2-methylpropionate), can be used as a polymerization initiator. In addition, each monomer is mix | blended so that each monomer may become specific mol with respect to the total amount (100 mol%) of all the monomers. The ratio of the structural unit which consists of each monomer in the copolymer of this invention is the same as the compounding quantity of each monomer at the time of copolymerization.

It is preferable to perform a polymerization reaction in a hydrophilic solvent. Examples of the hydrophilic solvent include ketone solvents such as acetone, methyl ethyl ketone and methyl isobutyl ketone, alcohol solvents such as methanol, ethanol, n-propanol, i-propanol, n-butanol, i-butanol and sec-butanol, and water. Etc. can be mentioned. These may be used independently or may use 2 or more types together. Among them, it is preferable to use an alcohol solvent.

It is preferable to use a polymerization initiator in the range of 0.01-5 mass% with respect to all monomers.

For example, the polymerization reaction can be carried out in an inert gas atmosphere such as nitrogen or argon, preferably at 30 to 120 ° C, more preferably at 40 to 100 ° C for 1 to 30 hours. After completion of the polymerization, the produced copolymer may be isolated from the reaction solution by any suitable means such as solvent distillation or addition of a poor solvent. This copolymer can be used as it is or by refining, for example, in the manufacture of cosmetics. Purification can be performed by combining suitable means, such as reprecipitation, solvent washing, membrane separation, etc. as needed.

Content of (A) component in hair cosmetics is 0.1-2 mass%, and 0.2-1.5 mass% is preferable. If it is less than 0.1 mass%, the effect of the hairiness of the hair, the smoothness of a hair, and the ease of application of a hair is hard to appear, and when it exceeds 2 mass%, the hair smoothness worsens.

The nonionic surfactant of the present invention uses HLB 14-18, preferably 15-18. In the nonionic surfactant of less than HLB 14, the smoothness of the hair worsens and the improvement effect on the storage stability cannot be exhibited. In addition, an HLB value is a value which shows the balance of the intensity | strength of the hydrophilic group and hydrophobic group which comprise surfactant, and is computed according to the following Kawakami's equation. In addition, in this invention, HLB is the value which rounded off the decimal point 1st term.

HLB value = 7 + 11.7 log (M _W / M _O )

M _W : Molecular Weight of Surfactant Hydrophilic Part

M _O : Molecular weight of surfactant lipophilic part

The said HLB means a weighted average value when 2 or more types of nonionic surfactants are used together. If the weighted average value is the range of 14-18, HLB of each nonionic surfactant may not be 14-18, but it is preferable that 1 type contains the nonionic surfactant of HLB14-18. In addition, the weighted average HLB value is a value obtained by multiplying the HLB value of the nonionic surfactant and the use weight of the nonionic surfactant with respect to all the nonionic surfactants, and adding the sum of the calculated values to all the nonionic surfactants. Means the value divided by the total used mass of the active agent.

As HLB18, monostearic acid polyethylene glycol (150EO) etc. are mentioned. Among them, in order to further exert an effect on the smoothness and preservation stability of the hair, a nonionic surfactant of HLB15 or more is preferable, and monostearic acid polyethylene glycol (150EO) of HLB18 is more preferable. EO is an abbreviation of ethylene oxide and POE is an abbreviation of polyoxyethylene.

Content of (B) component in hair cosmetics is 0.1-3 mass%, and 0.3-1 mass% is preferable. If it is less than 0.1 mass%, storage stability will worsen, and when it exceeds 3 mass%, there will be no brittleness of hair, the hair smoothness will worsen, it will become difficult to melt | dissolve in another raw material, and it will become difficult to mix | blend.

Moreover, the mass ratio of (A) component and (B) component represented by (A) / (B) is 0.05-18.00, and 0.60-5.00 is preferable. If the mass ratio is less than 0.05, the smoothness of the hair deteriorates, and if it exceeds 18.00, it adversely affects the storage stability, the ease of application, and the smoothness of the hair. The ratio is rounded off to the third decimal point.
