Description

Makeup cosmetic composition for absorbing sebum and preparation method thereof {A makeup composition for absorbing sebum and preparation method thereof}

The present disclosure relates to a makeup cosmetic composition for absorbing sebum, including a porous powder with a wax coating film, and a method for manufacturing the same.

Persistence, which allows makeup to remain similar to its original state for a long time, is a very important attribute in makeup. For this purpose, various technologies are used, such as using a film former, surface modification to increase the adhesion of the pigment to the skin, and using oil-absorbing powder.

Oil-absorbing powder is mainly used as a powder having a porous or hollow structure, and is used to prevent the sebum from deforming the makeup film by absorbing sebum from the skin into the pores of the powder. The higher the content of this oil-absorbing powder, the less the makeup film is damaged by sebum, but at the same time, there is a limit to increasing the content indefinitely as disadvantages such as stiffness and dullness appear when applied to the skin. Therefore, when using the same amount of powder, depending on how many pores and large surface area the oil-absorbing powder has, the oil-absorbing effect can be increased even though a small amount is used.

The most commonly used oil-absorbing powder is silica or silica-based modified material with high oil absorption. However, many oil-absorbing powders containing silica or silicone-based products generally have poor affinity between their surfaces and sebum, so there is a limitation in that the actual oil absorption amount does not have the best effect compared to the large surface area of the pores.

1. Preparation of a makeup cosmetic composition for sebum absorption containing wax-coated porous powder

A makeup cosmetic composition for sebum absorption was prepared according to the composition in Table 1 below. In both comparative examples and examples, except for the process of making a pre-dispersion composition, the oil phase containing an emulsifier is first mixed, similar to the manufacturing method of a general face makeup product, and the powder and pigment are dispersed through homomixing, and then the dissolved It was prepared in the same manner by adding water to emulsify. In the case of the wax coating powder pre-dispersion composition, which is the first step in creating the oil phase, it is manufactured through high-strength dispersion using the mixing ratio suggested in the above description. Afterwards, the preparation of the oil phase is completed by adding additional dispersion by adding the remaining oil components of the makeup cosmetic composition and other components that disperse in the oil components. In the case of wax, coating can be made possible by heating and dissolving separately or by naturally heating and dissolving during the high-intensity dispersion process.

2. Sebum affinity by wax type

Sebum-like oil (caprylic/capric triglyceride) and wax are mixed at a weight ratio of 7:3 in a dissolved state at 90°C, then naturally cooled and 24 hours after reaching room temperature. The stability pattern was confirmed.

As a result, it was confirmed that all waxes containing silicone, such as dimethicone and silane, have poor affinity for sebum as the wax precipitates or separates, while polyethylene, tribehenin, microcrystalline wax, ozokerite, etc. It was confirmed that the silicone-free wax had good affinity for sebum through stable mixing without separation.

3. Check sebum absorption amount according to coating aspect

(1) Coating pattern according to the input stage and weight ratio of wax and porous powder

When wax is not added together in the pre-dispersion step of dispersing volatile oil and porous powder and is later added to the dispersion step in a non-volatile solvent (Comparative Example 2), the porous powder (silica) is added as shown in (a) of Figure 1. ), no wax coating layer was formed. In addition, when the volatile solvent, wax, and porous powder were dispersed together in a non-volatile solvent without a pre-dispersion step (Comparative Example 3), again, a wax coating layer was not formed on the porous powder as shown in (b) of FIG. 1.

On the other hand, when wax, porous powder, and volatile oil were added together in the pre-dispersion step (Comparative Example 4, Example 1, and Example 2), a coating layer was formed on the surface of the porous powder as shown in (d)-(e) of Figure 1. was formed.

Meanwhile, in the case of Comparative Example 4 in which the weight ratio of wax and porous powder in the pre-dispersion step was 1:50, the wax was not uniformly coated on the inner surface of the porous powder, as shown in FIG. 1(c). On the other hand, in the case of Examples 1 and 2 where the weight ratios of wax and porous powder were 1:1 and 1:0.2, respectively, a wax coating layer was uniformly applied to the inner surface of the porous powder as shown in Figures 1(d) to (e). This is formed.

Additionally, in Example 2, where the weight ratio of wax and porous powder is 1:0.2, wax is excessively coated on the inner and outer surfaces of the porous powder, as shown in Figure 1(e), whereas the weight ratio is 1:1. In Example 1, the inner and outer surfaces of the porous powder were thinly and uniformly coated, as shown in Figure 1(d).

(2) Check the oil absorption amount of wax-coated porous powder

Based on the wax coating aspect of the porous powder, in order to determine whether there is a difference in oil absorption when applied to the skin, the compositions of Comparative Examples 2 to 4 and Examples 1 and 2 were applied to a membrane (sebum-permeable). 50 mL was applied on the surface, dried, and then 50 mL of sebum oil was sprayed from the back (considering the amount of oil absorbed by the artificial skin itself, the pattern was confirmed after 30 minutes (Figure 3). .

As shown in the schematic diagram of Figure 2, in Comparative Examples 2 and 3, the surface of the porous powder was not properly coated with wax, so the porous powder with low affinity for sebum absorbed less sebum, and in Comparative Example 4, the inner surface As the affinity for sebum was low, sebum could not enter the pores efficiently, resulting in low oil absorption. In Example 2, there was insufficient space to absorb sebum inside the porous powder due to excessive coating. On the other hand, in the case of Example 1, a thin and uniform wax coating layer was formed, resulting in sufficient space for sebum absorption inside the porous powder.

4. Sensory evaluation

For the sensory evaluation, 8 people applied 50 mL of the contents to their entire face by hand and scored their self-judgment regarding shine and persistence.

The evaluation score standard was 5 points each for shine and persistence after 8 hours of makeup, with the highest score being scored as the shine was more severe and the consistency was better. Shininess was assessed by how much oil was visible, and sustainability was assessed by the level at which the coverage of the makeup was maintained. Each was rated as 5 points for very strong, 4 points for slightly strong, 3 points for average, 2 points for insufficient, and 1 point for very weak. Table 3 is a table showing the average score of the shine and sustainability sensory evaluation results for each Example and Comparative Example, and Table 4 shows the individual score table of each panel. As a result, compared to the comparative examples, the shine of Examples 1 and 2 was low and the sustainability was high. In particular, Example 1 showed good results in terms of both shine and sustainability.

5. Clinical trials
