Description

Composition for scalp or hair comprising spherical materials {Composition for scalp or hair comprising spherical materials}

The present invention relates to a composition for scalp or hair with enhanced delivery of active ingredients using a spherical material, and more particularly, to a composition for enhancing delivery of active ingredients including a spherical polymeric material. In addition, the present invention relates to a hair dye composition comprising the above composition.

The purpose of using a cosmetic, hair, or oral composition is to more efficiently deliver an effective substance added for skin, hair, or oral beauty or health to a substrate. Devices or invasive methods used to enhance the delivery of active ingredients are time-consuming and costly, and in some cases require specialized treatment. Cosmetics refer to items used in a similar way, such as applying to the human body to clean and beautify the body to add charm, brighten the appearance, or maintain or promote the health of the skin and hair. It can be said that it is an important factor to more effectively deliver an effective substance suitable for various purposes to the skin, hair, or mouth.

According to prior literature, technology designed to encapsulate active ingredients inside particles for drug delivery (Korean Patent 0001) or combine thickeners and emulsifiers to form particle microemulsions so that they can penetrate through skin cell gaps (Korean Patent 0002) However, such encapsulation requires an additional process for encapsulation and conditions for maintaining stability. Most of the conventional techniques correspond to increasing the transfer amount or adhesion (adsorption) amount by changing the surface properties of a substrate or changing the interaction force between a material and a substrate. These techniques also have a limitation in that they can be applied only when the surface characteristics of the substrate meet specific conditions that can cause an interaction force.

Experimental Example 1. Comparison of effective ingredient delivery enhancing effect of linear/spherical polymers

1-1. Comparison of delivery enhancing effect in oxidative hair dyes

In this experimental example, an experiment was performed using a spherical polymer having a diameter of about 100 um (FIG. 1).

Specifically, Table 1 and FIG. 2 show the results of mixing oxidative hair dye as an active ingredient in aqueous solutions containing 0.15% and 0.5% of spherical and linear polymers, respectively, and dyeing gray hair using this. The staining efficiency was measured using a color difference meter (Equation 1) and expressed using delta E, the amount of change in the measured L, a, and b values, respectively. The higher the delta E, the better the color development. After applying a formulation equivalent to about 3 times the weight of the hair by hand for 1 minute, leave it for 5 minutes, rinse thoroughly with tap water, and then dry it completely using a hair dryer. After that, the hair dyeing efficiency is calculated using a color difference meter, and at this time, the average value of the results of 9 repetitions is used.

(Equation 1)

L is the brightness difference; A positive number means light, a negative number means dark.

a is a red-green difference, meaning that a positive number means red, and a negative number means green.

b means the yellow-blue difference, and the positive number corresponds to yellow, and the negative number corresponds to blue.

* Stickiness (panel test, n=12)

1: not very sticky, 2: not sticky, 3: normal, 4: sticky, 5: very sticky

Comparing the same amount of linear/spherical sodium polyacrylate, the ΔE of Comparative Example 2 was 52.1, the ΔE of Example 1 was 56, the ΔE of Comparative Example 3 was 52.4, and the ΔE of Example 2 was 63. When the rate was the same, the hair dyeing efficiency was much higher. In particular, looking at the results of Example 1 and Comparative Example 3, it can be seen that the hair dyeing efficiency of Example 1 is high, even though the spherical sodium polyacrylate is used in a much smaller amount. In addition, Examples 1 and 2 including the spherical polymer exhibited superior viscosity without stickiness than Comparative Examples 1 to 3 including the linear polymer. In addition, in the case of a linear polymer, it is common for viscosity to increase and stickiness to occur as the usage amount increases, but it was confirmed that there is no stickiness even when the usage amount of a spherical polymer is increased.

1-2. Comparison of delivery enhancing effect in non-oxidizing hair dyes

The results in Table 2 below are experiments using acid red 33, a non-oxidizing hair dye, and sodium polyacrylate and xanthan gum were used as linear polymers and sodium polyacrylate as spherical polymers. Dyeing test conditions and measurement of color difference are the same as above.

As for the results of the non-oxidizing hair dye, the hair dyeing efficiency of the spherical sodium polyacrylate was higher when the same amount was used (Comparative Example 5 vs. Example 3, Comparative Example 6 vs. Example 4).

From the results of Tables 1 and 2, it was confirmed that the aqueous solution containing the spherical polymer delivered more dye to the hair, resulting in higher dyeing efficiency compared to the case containing the linear polymer. This phenomenon was a phenomenon that appeared in both oxidized and non-oxidized hair dyes, regardless of the type of hair dye.

1-3. Comparison of transfer enhancement effect in non-oxidizing hair dye applied to shampoo formulation

The results of Table 3 and FIG. 3 below confirmed the hair dyeing efficiency by applying linear polyacrylate, xanthan gum and spherical polyacrylate applied to the shampoo formulation in order to compare the experiments conducted in the polymer aqueous solution state in Tables 1 and 2. . The dyeing and color difference measurement conditions are the same as the experimental methods in Tables 1 and 2.

Similarly, in the comparative experiment in the shampoo formulation, the spherical sodium polyacrylate showed a much higher hair dyeing efficiency than the linear one (Comparative Example 9 vs. Example 5, Comparative Example 10 vs. Example 6). It can be seen that when the shampoo formulation contains an appropriate amount of the spherical polymer, the coloring power is higher than that when the linear sodium polyacrylate and xanthan gum are included.

Table 4 and FIG. 4 are experiments for confirming the effective substance penetration efficiency into the skin by adding a fluorescent substance (fluorescein) to an aqueous polymer solution containing the same content of linear and spherical sodium polyacrylate and applying a certain amount to pig skin. ^o C Corresponds to the result of measuring skin permeability after leaving it in an oven with a relative humidity of 50% for 18 hours.

Table 4 shows the results of quantitative analysis of the amount of substances that penetrated the skin and penetrated the skin when the aqueous polymer solution containing the fluorescent substance was applied to the pig skin and left for 18 hours. Compared to Comparative Example 12 without polymer or Comparative Example 13 including linear polymer, it was confirmed that a significantly larger amount of fluorescent material was obtained when the spherical polymer was included.

The difference in dyeing power was confirmed by adjusting the conditions of the rinsing water used when washing the shampoo formulation.

Table 5 shows the difference in dyeing power when washed with warm water and cold water. As in Example 6-1, when spherical sodium polyacrylate was used and washed with lukewarm water, the greatest dyeing effect was shown. When spherical sodium polyacrylate was used and washed with cold water, the dyeing effect was 43.79% lower than when washed with lukewarm water, and 11-2 using the same conditions as Example 6-1 but using xanthan gum had a 51.62% lower dyeing effect. showed
