Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a first agent composition for a two-bath permanent wave agent, a two-bath permanent wave agent comprising the first agent composition, and a permanent wave treatment method.
[0002]
[Prior art]
In the permanent wave treatment, it is an important requirement to give the hair wave good elasticity. In addition, it is generally avoided that the hair is “stiff” in relation to the elasticity of the wave.
[0003]
Conventionally, as one means for imparting good elasticity to the wave of hair, an attempt has been made to add a polymer compound to the first agent composition and / or the second agent composition of permanent wave agents. ing.
[0004]
In addition, for example, in the invention of “Permanent Wave Agent Composition” of Japanese Patent Application No. 9-315824 (Japanese Patent Application Laid-Open No. 11-130637) relating to the application of the present applicant, the first agent composition of the permanent wave agent and / Or carboxyvinyl polymer, acrylic acid methacrylate alkyl copolymer, highly polymerized silicone, predetermined cationic polymer, etc. are blended into the second agent composition and succeeded in giving an excellent texture to hair. Yes.
[0005]
[Problems to be solved by the invention]
However, the above-mentioned conventional polymer compounds are not always sufficient for the purpose of giving good elasticity to the wave of hair and reducing the feeling of stiffness.
[0006]
In other words, if a large amount of polymer compound is blended, a good wave elasticity can be obtained, but a sense of stiffness can be obtained. Conversely, if a compound amount of the polymer compound is suppressed, the stiffness can be avoided, but the wave should have a good elasticity. There was a problem that I could not.
[0007]
Moreover, in the invention described in the above-mentioned JP-A-11-130637, an excellent texture is given to the hair. This is because the polymer compound accumulates on the surface of the hair when it is repeatedly treated, depending on the condition of the hair. For the reason of feeling stiff, it did not necessarily mean imparting good elasticity and reducing the stiff feeling.
[0008]
Then, this invention makes it the subject which should be solved to provide the agent for two bath type permanent waves which gives a favorable elasticity to the wave of hair in the permanent wave treatment, and reduces a feeling of stiffness well.
[0009]
【Viewpoints】
In the research process for solving the above-mentioned problems, the inventor of the present application has achieved good hair properties by blending the alkyl acrylate copolymer emulsion with the first agent composition and / or the second agent composition of the permanent wave agent. I have learned for the first time that it is possible to achieve both elasticity and reduction of stiffness. In addition, it is particularly effective to contain an alkyl acrylate copolymer in the first agent composition, and the trade name “Aculin 33” of Rohm & Haas is extremely effective as the alkyl acrylate copolymer. I knew that.
[0010]
Aculine 33 and its similar product, Aculin 22 (trade name of Rohm and Haas), have conventionally been exclusively hair dyes (JP-A-7-82122, JP-A-10-316546) and hair styling agents (patent no. No. 3091444), and the purpose of use thereof is to increase the viscosity of hair dyes and hair styling agents, and has never been blended into permanent wave agents for the purpose of the present invention.

[0050]
【Example】
The permanent wave agent 1st agent of the composition shown in Example 1-Example 5 (represented as "Actual 1" etc.) and Comparative Example 1-Comparative Example 3 (represented as "Ratio 1" etc.) in the last Table 1 and A second agent was prepared for each. Numerical values in the table indicate parts by weight.
[0051]
( Wave elasticity evaluation )
Using hair subjected to bleach treatment (28% aqueous ammonia; 2.5%, 35% hydrogen peroxide; 3%) three times, a plurality of hair bundles having a hair amount of 0.4 g and a length of 20 cm are formed. It was uniformly wound around a 1.5 cm diameter plastic rod.
[0052]
And after apply | coating 1 mL each of the 1st agent which concerns on the said Example 1- Example 5 and the comparative example 1- comparative example 3 with respect to these hair bundles uniformly, these are accommodated in the bag made from vinyl with the plastic rod. Then, it was closed and placed in a constant temperature bath at 37 ° C. and allowed to stand for 15 minutes. Thereafter, each hair bundle is taken out of the bag and washed with water for 1 minute, and then 0.5 mL of each of the second agents according to Examples 1 to 5 and Comparative Examples 1 to 3 is uniformly applied, Left at room temperature for 5 minutes.
[0053]
The above second agent application operation was repeated once more, and then washed with water, and the hair bundle was carefully removed from the plastic rod to obtain a coiled wave. The hair bundle according to each example was hung by its own weight while grasping one end thereof, and the wave length from the upper end to the lower end of one coil was measured.
[0054]
As the wave length value measured as described above is smaller, the wave is evaluated as having higher elasticity, and the wave elasticity of the hair bundle according to each example is evaluated in the following four stages using Comparative Example 1 as a control. “◎: elastic and wave uniform. ○: elastic. Δ: comparable to Comparative Example 1. ×: slightly inferior to Comparative Example 1.” It was shown in 1) in the “Evaluation” column.
[0055]
In addition, as an evaluation at the time of continuous use of the permanent wave agent, the elasticity of the wave is also evaluated when the entire process of the permanent wave treatment is repeated three times, and the evaluation result is shown in Table 1 as “Evaluation”. Shown in 4) of the column.
[0056]
( Evaluation of hair feel )
Using hair subjected to bleach treatment (28% aqueous ammonia; 2.5%, 35% hydrogen peroxide; 3%) three times, a plurality of hair bundles having a hair amount of 1.0 g and a length of 15 cm were constructed. Wound uniformly on a plastic rod.
[0057]
And after apply | coating 1 mL each of the 1st agent which concerns on the said Example 1- Example 5 and the comparative example 1- comparative example 3 with respect to these hair bundles uniformly, these are accommodated in a vinyl bag with the plastic rod. Then, it was closed and placed in a constant temperature bath at 37 ° C. and allowed to stand for 15 minutes. Thereafter, each hair bundle is taken out of the bag and washed with water for 1 minute, and then 0.5 mL of each of the second agents according to Examples 1 to 5 and Comparative Examples 1 to 3 is uniformly applied, Left at 25 ° C for 10 minutes.
[0058]
Thereafter, washing with water was performed, and the feel of the hair at the time of washing with water was evaluated as the feel at the time of plain rinsing. Furthermore, after the obtained wavy hair was naturally dried, the feel when dry was evaluated. All of these touch evaluations were evaluated by the touch of five professional panelists, and the following four levels were evaluated using Comparative Example 1 as a control. “◎: Extremely smooth and moist feel. ○: Smooth feel. Δ: Feel comparable to that of Comparative Example 1. ×: Fewer and more harsh than Comparative Example 1. Is. "
[0059]
The evaluation results of the feel during plain rinsing are shown in 2) in the "Evaluation" column of Table 1, and the evaluation results of feel during dry are shown in 3) of the "Evaluation" column of Table 1. In addition, as an evaluation at the time of continuous use of the permanent wave agent, the feeling during plain rinsing and the feeling during drying were also evaluated when all the processes of the permanent wave treatment were repeated three times. The results are shown in 5) and 6) in the column.
[0060]
( Comprehensive evaluation )
From the evaluation of the elasticity of the wave and the evaluation of the feel of the hair, the quality of the permanent wave agent according to each example was comprehensively evaluated using Comparative Example 1 as a control. In the evaluation symbols, ◎ means “very high quality”, ○ means “high quality”, and Δ means “quality equivalent to that of Comparative Example 1”.
