Description

  TECHNICAL FIELD The present invention relates to a permanent wave second agent and a permanent wave agent, and more particularly to a permanent wave second agent and a permanent agent using the second agent, which reduce damage to hair and have excellent wave forming ability. About.

As a permanent wave agent used for imparting a wave shape to hair, a permanent agent is conventionally composed of a first agent containing a reducing agent and a second agent containing an oxidizing agent. Wave agents are widely used.
In particular, the second agent fixes the disulfide bond, which is cleaved by the first agent, and is inherent in the hair, by re-forming with an oxidizing agent, in a desired shape.

The permanent wave treatment using these permanent wave agents is a chemical treatment under severe conditions for the hair because the hair is exposed to an oxidizing agent or a reducing agent.
Therefore, the hair is considerably damaged.
As a result, the moisture retention, flexibility, surface smoothness, etc. of the hair are lost, and the feel of the touch is impaired by causing the hair to become brittle, reduced in firmness, dry, split, and broken. Has led to a decline.

  As the second agent for permanent wave, for example, an oxidizing agent composition (I) in which bromate (I) is blended with JP 2013-14523 A (Patent Document 1) in order to increase wave forming power. And a second agent for permanent wave comprising: an oxidant composition (II) containing a bromate (II) to be applied to hair after the oxidant composition (I) is applied. In addition, the concentration of bromate (II) in the oxidant composition (II) is lower than the concentration of bromate (I) in the oxidant composition (I). Two agents are disclosed.

JP-A 2007-57335 (Patent Document 2) discloses a second agent used for permanent wave treatment, which contains sodium carboxymethyldextran, and has a permanent wave second agent. It is disclosed.
Furthermore, Japanese Patent No. 3730925 (Patent Document 3) contains an oxidizing agent, carboxymethyl cellulose, and polyacrylic acid or a salt thereof, and includes carboxymethyl cellulose (1) and polyacrylic acid or a salt thereof (2). A permanent wave second agent having a weight ratio of (1) / (2) = 20/80 to 75/25 is disclosed in Japanese Patent No. 4612250 (Patent Document 4). A composition comprising at least hydrogen peroxide as an oxidizing agent, an acidic amino acid and a basic amino acid, a buffer system is constituted only by the acidic amino acid and the basic amino acid, and 0.025 gram equivalent A second agent composition for permanent wave, characterized by having a buffer capacity of / L or more is disclosed.

  However, these conventional second agents for permanent wave do not improve the wave forming ability without increasing the blending amount of the oxidizing agent, and do not damage the hair, but have the ability to form a wave shape on the hair. Increasing permanent wave agents are expected.

The present invention is illustrated by the following examples and test examples, but is not limited thereto.
(Examples 1 to 5 and Comparative Examples 1 to 3)
Purified water was added to liquid paraffin, polyoxyethylene oleyl ether, and sorbitan monooleate to prepare an emulsion (A). Separately, a mixture of purified water and glycerin was added to ubiquinone, squalane, polyoxyethylene oleyl ether phosphate, and methyl paraoxybenzoate to prepare a solubilized solution (B). Squalane was used for dissolving ubiquinone.
To purified water, add ethylenediaminetetraacetic acid disodium dihydrogen (EDTA-2Na), which is a chelating agent, sodium bromate, which is an oxidizing agent, sodium phosphate, and disodium phosphate, which are pH adjusting agents. The emulsified product (A) and the solubilized product (B) were added to prepare the second agent for permanent wave shown in Table 2.

Test Example Wave Efficiency Test Using each of the permanent wave second agents obtained in Examples 1 to 5 and Comparative Examples 1 to 3, the wave efficiency in combination with the permanent wave first agent having the composition shown in Table 1 below. The test was conducted.
-Preparation of the first agent for permanent wave Emulsions (C) were prepared by adding purified water to liquid paraffin, polyoxyethylene oleyl ether, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride at each mixing ratio shown in Table 1. . Next, cysteamine hydrochloride, which is a reducing agent, pentasodium diethylenetriamipentaacetate (DTPA-5Na), which is a chelating agent, and aqueous ammonia, which is an alkaline agent, are added to and mixed with purified water, and an emulsion (C) is added thereto. The first agent a for permanent wave shown in Table 1 was prepared.

The wave efficiency test was evaluated by the Kilby method.
Specifically, a test hair bundle (about 10 cm in length) is fixed to a Kilby device, and first, each first agent having the composition shown in Table 1 is immersed in the test hair bundle (30 ° C., 10 minutes). And washed with running water for 1 minute.
Next, each second agent was immersed in the test hair bundle (30 ° C., 10 minutes) and washed with running water for 1 minute.
Thereafter, the treated hair bundle was removed from the device of Kilby and floated on the water for 10 minutes, and the measurement was performed between the five waves.

Each wave efficiency (%) was calculated from the measurement values obtained in this way using the following wave efficiency calculation formula.
The results are shown in Table 2 below.

Wave efficiency (%) = 100− [100 × (B−A)] ÷ (C−A)
A: Distance between the first and sixth rods of the kirby apparatus (actual measurement of the center point of the rod) (mm)
B: Length (mm) between 6 piles of curled hair.
C: Length (mm) of six piles when curled hair is straightened.
A summary of A, B, and C is shown in FIG.

From Table 2 above, it can be seen that when the second agent for permanent wave of the present invention is used, the wave efficiency is excellent even if the blending amount of the oxidizing agent contained in the second agent is small.
On the other hand, when using the 2nd agent of the comparative example 1 which does not contain ubiquinone, it turns out that wave efficiency is inferior compared with the Example in which the oxidizing agent is mix | blended in the same quantity.
Moreover, when the 2nd agent of the comparative example 3 which does not contain ubiquinone is used, in order to make wave efficiency substantially equivalent to an Example, it turns out that it is necessary to use much sodium bromate which is an oxidizing agent. .
Even when ubiquinone is blended, it can be seen that in Comparative Example 2 that does not include a predetermined blend, the wave efficiency is inferior compared to the Examples.

  The permanent wave second agent of the present invention is combined with an arbitrary first agent available in any market, and a wave agent that forms waves and curls on straight hair and a curly hair, a curly hair, and a wave that straightens the wave. It can be used as a hair straightener.
