Description

Protein-containing hair perm supplement composition {Protein-containing hair perm supplement composition}

The present invention relates to a protein-containing hair perm aid composition, and more specifically, to a protein-containing hair perm aid composition that has excellent cystine bond restructuring to facilitate the formation of hair perm waves and at the same time minimizes hair damage. will be.

Recently, modern people have many ways to be exposed to others, and the cost and time spent on decorating not only their appearance but also their hair is increasing. In particular, Asian hair is straight, has a wide diameter, and is thick and long, so hair care is difficult without hair perming. As a result, hair perm is the service that generates the most sales among the types of hair care services provided in Korean beauty salons.

Conventional hair perms used for hair perming are alkaline products with a pH of 8 or higher, and the alkaline ingredients act on hair containing keratin protein as its main component, causing damage to the hair cuticle. For this reason, as hair beauty services increase, the hair damage of those who use them is becoming more severe.

When hair becomes damaged, there is no choice but to adjust the pH of the hair perm to minimize further damage. Generally, a weakly acidic perm agent with a low pH is used for damaged hair. According to Korea's current hair cosmetics management law, the ratio of reducing agent in the content ratio of hair perm agent 1 is determined in proportion to the pH concentration. As hair damage accelerates and the pH concentration of the hair perm agent gradually decreases, the content of the reducing agent also decreases.

In order to achieve satisfactory hair perm results, the cystine bond, which is the side chain bond of the keratin protein present in the fur cortex, must be restructured by more than 70% with an appropriate amount of reducing agent. This cystine bond becomes cysteine in the process of reduction, and is oxidized again to restructure into the original cystine. Since the waveformability of the hair perm is determined through this restructuring of the cystine bond, if the reduction reaction does not occur properly, oxidation will eventually occur. The process is also weakened, which causes the hair perm treatment results to be unsatisfactory.

As a result, when damage occurs to the hair, the restructuring process of cystine bonds is not carried out smoothly, resulting in poor wave formation. Additionally, since the main ingredient of conventional hair perm aids consists only of reducing agents, hair damage continues. This is resulting in maximizing results.

Accordingly, in consideration of such problems, the present invention provides a protein-containing hair perm aid composition that can expand the cystine reaction to ensure good restructuring of the cystine bond while minimizing hair damage during hair perm treatment. .

Therefore, the purpose of the present invention is to provide a protein-containing hair perm aid that can serve as both a hair perm aid and damaged hair care.

Experimental Example 1: Comparative experiment of wave formation of hair perm aids

In Preparation Example 1-2, the permed hair was placed on graph paper, and the length of one wave cycle formed by the perm was measured from the starting point to the ending point to the crest to obtain the wave formation degree. Through this, the effect of the presence and type of auxiliaries on hair wave formation was analyzed.

Wave formation = (Length of one cycle of S curls with additives/Length of one cycle of S curls without additives)*100

After performing a hair perm on the four hair bundles treated in Preparation Example 1-2, the shape of the hair curls is shown in Figure 1.

Comparative Example 1 (pH 8.2 pumping agent used, no auxiliary added), Comparative Example 2 (pH 8.2 pumping agent used, commercial auxiliary MC added), Comparative Example 3 (pH 8.2 pumping agent used, commercial auxiliary mol beads added), Example ( The length of one cycle of the wave measured to verify the wave formation of the hair perm aid at pH 8.2 (use of perm agent, addition of Boosting K) is shown in Table 3 below.

Supplement Types Wave 1 cycle length (mm) Wave formation (%) Comparative Example 1 No additives added 109.5 100 Comparative example 2 Addition of commercially available supplement MC 105.8 103 Comparative Example 3 Addition of commercially available auxiliary mol beads 97.0 113 Example Development supplement Boosting K added 80.1 137

Comparative Example 1 (pH 8.2 pump used, no additives added) 109.5 mm, Comparative Example 2 (pH 8.2 pump used, commercial auxiliary MC added) 105.8 mm, Comparative Example 3 (pH 8.2 pump used, commercial auxiliary mol beads added) 97.0mm and 80.1mm in the example (pH 8.2 pump used, boosting K added), respectively. Comparing the length of one cycle of the wave, the length of one cycle of the wave of Example (Boosting K) is 80.1 mm compared to the results of Comparative Example 1 (no additives), Comparative Example 2, and Comparative Example 3 (two types of commercially available auxiliaries). You can check that it is the shortest. Therefore, it can be assumed that perming by adding boosting K in Example has a positive effect on wave formation.

To clearly confirm this, it was converted into wave formation as shown in Table 3 above. The wave formation of the hair of Example (pH 8.2 perm agent used, Boosting K added) was 137%, which was 37% higher than that of the hair of Comparative Example 1 (pH 8.2 perm agent used, no auxiliary added). Comparative Example 2, Comparison The wave formation value was also higher than that of the hair of Example 3 (pH 8.2 perm agent used, commercially available auxiliaries added), and it is judged that Boosting K, which is an example, has a significant effect on the wave formation of hair when performing a hair perm. (See Figures 1 and 2)

2. Comparison experiment of protein content of hair perm supplements

Preparation Example 2-1: Sample hair preparation

In order to test the effectiveness of protein-containing hair perm supplements, sample hair was created by mixing bleach and 6% oxidizing agent in a 1:1 ratio and applying it to 500 g of commercially available level 3 hair, leaving it for 30 minutes and then shampooing it.

Preparation Example 2-2: Hair treatment

A reducing agent was prepared by mixing the hair perm agent (pH 8.2) and the auxiliary agents prepared in the above examples and comparative examples in a ratio of 4:1 (8 g of perm agent, 2 g of auxiliary agent). Sample hair A, which is Comparative Example 1, was manufactured by applying only a hair perm agent (pH 8.2) without adding any auxiliaries to the sample hair, and sample hair B and C, which are Comparative Examples 2 and 3, were prepared by applying a hair perm agent (pH 8.2) to the sample hair. ) and two commercial auxiliaries (auxiliary MC and auxiliary mol beads) were added respectively. Then, sample hair D treated with hair perm agent (pH 8.2) and Example Boosting K was prepared, and each was softened three times. 10 g of reducing agent was applied to each sample hair and left to naturally stand at room temperature for 20 minutes. After washing with water, an oxidizing agent was applied, left for 10 minutes, shampooed with acidic shampoo, washed three times, and natural drying was repeated three times. The specific preparation method is shown in Table 4 below.

Experimental Example 2: Comparative experiment of protein content of hair perm supplements

The quantitative measurement of protein content of sample hairs A to D treated by the above method was analyzed to determine which sample hair had the highest protein content.

At this time, hair protein was quantitatively analyzed using the semimicro Kjeldahl method. The analysis method was to take 0.1 g of hair sample, add 20 ml of sulfuric acid, heat decompose it using a protein decomposition device (DK 8, VELP Scientipia, Italy), and then obtain the crude protein content (%) through distillation and titration processes. The protein content per unit length of hair was calculated using the crude protein content and protein weight per unit length of hair.

The comparison sample hair treated in Preparation Example 2-1 was softened by adding sample hair A treated with only hair perm agent, hair perm auxiliary MC, mole beads, and boosting K, and sample hair B, C, and D were obtained by unit length of the sample, respectively. The efficacy of the developed product was compared and verified by measuring the weight of each hair (㎍/cm) and hair protein content (㎍/㎝). As a result of efficacy verification, the protein content per unit length of hair is shown in Table 5 below.

Processing method Hair protein content (μg/cm) Hair protein content ratio (%) Control example virgin hair 39.46±3.84 100% Comparative Example 1 Sample hair A
1 time bleaching, 3 times perm 35.10±5.38 89% Comparative example 2 Sample hair B
Sample hair A+ (MC) 44.12±9.09 112% Comparative Example 3 Sample hair C
Sample hair A+ (molar beads) 38.28±9.49 97% Example Sample hair D
Sample hair A+ (boosting K) 48.01±5.33 122%

As a result of the above experiment, when the protein content of the control example virgin hair was set as 100%, the hair protein content of Example Boosting K was 122%, which was higher than that of the control example virgin hair. In addition, from the measurement results in Table 5, it was confirmed that when hair perm was performed with Example Boosting K, the wave formation and protein content were higher than those of Comparative Examples (1 to 3).

Therefore, from the experimental results of Experimental Examples 1 and 2, when hair perm was performed using the protein-containing hair perm aid composition according to the example of the present invention, when hair perm was performed according to Comparative Examples (1 to 3), By comparison, it can be seen that both wave formation and protein content are excellent.
