Description

Bubble type cleansing cosmetic composition for removing keratin {Bubble type cleansing cosmetic composition for removing keratin}

The present invention relates to a bubble-type cleansing cosmetic composition with excellent exfoliation effect and a manufacturing method thereof.

There are various stimuli that the skin receives, and examples thereof include natural stimuli such as strong wind, extreme heat, extreme cold, and ultraviolet rays, and artificial environmental stimuli such as air pollutants and acid rain. These stimuli can be further classified into physical and chemical stimuli. The outermost epidermal layer of the skin has various defense mechanisms to effectively defend against various stimuli and contaminants that come into contact with the skin, and a representative mechanism that effectively defends against these stimuli is the keratin defense.

Our skin undergoes a turnover process in which keratinocytes generated in the basal layer are naturally shed every 28 days and new cells are created. However, when the skin's defense system collapses due to internal and external factors, it is immediately reflected on the skin and requires periodic exfoliation. Cosmetics for exfoliation are largely divided into chemical peeling agents and physical peeling agents. Chemical exfoliants use acid ingredients such as AHA (Alpha Hydroxy Acid) or BHA (Beta-Hydroxy Acid) to loosen the link between the thick stratum corneum on the skin, thereby chemically dissolving dead skin cells or turning the skin on. It is a formulation that removes dead skin cells by shortening the over cycle. In the above case, a certain degree of exfoliation effect can be obtained when used for a certain period of time, but most of them have the disadvantage of causing side effects by irritating the skin by using chemically active substances having a very low pH.

A physical exfoliant is a scrub agent that removes dead skin cells by rubbing various types of granules with the skin in a cream or gel type formulation. In this case, there are no chemical skin side effects compared to chemical exfoliation formulations, but since the scrub is forcibly peeling off the dead skin cells, it is highly irritating to the skin and has disadvantages that are inconvenient during use. Gommage type exfoliant, one of the physical exfoliants developed to overcome these disadvantages, is applied and rubbed, and the contents are pushed out like dirt, adsorbing dead skin cells and wastes on the surface of the skin. It has the advantage of being less stimulating than that, so research on this is increasing.

Exfoliation is the most important process of skin care that promotes the regeneration cycle of cells, making the skin bright and transparent, and helping healthy skin regeneration by making the skin texture dense and smooth. However, since excessive exfoliation can impair the skin barrier function and make it sensitive, as well as exacerbate the irregular turnover cycle, it is necessary to develop a mild exfoliant with good exfoliation efficacy and low irritation.

On the other hand, the cleansing cosmetic composition is collectively referred to as a cleanser, and the existing cleanser is largely emulsified type of cleansing cream and cleansing lotion; Oil type cleansing oil; and water-type cleansing water. Recently, consumers are diversifying their criteria for choosing cosmetics, and it is known that new textures and methods of use account for a large portion of them. In response to such consumer demand, new formulations such as bubble-type cleansing that generate fine bubbles are being developed.

Accordingly, there is a demand for the development of a cleansing cosmetic composition capable of overcoming the limitations of cosmetic compositions for removing dead skin cells and removing dead skin cells in daily life without skin irritation.

The present inventors have made intensive research efforts to develop a cleansing cosmetic composition that can gently remove dead skin cells in daily life without skin irritation and has excellent cleansing power. As a result, the present invention was completed by developing a bubble-type cleansing cosmetic composition that cleanses with rich foam and can effectively remove dead skin cells by generating gommage when rubbed.

Specifically, after dissolving polyacrylic acid carbomer in purified water, it was stirred at 3000 rpm with an Agimixer to form a polymer matrix. Then, steartrimonium methosulfate, a quaternary ammonium salt, was added to the polymer matrix and mixed at 3000 rpm with a homomixer to prepare a first mixture. Then, cocoglucoside, a nonionic surfactant, and sodium chloride, a salt, were added to the first mixture, and then mixed at 2000 rpm to decrease the viscosity of the mixture, thereby preparing a second mixture. Then, PEG-8, a polyol, was added to the second mixture, mixed at 2000 rpm with a homomixer, and subjected to a defoaming process to prepare Examples 1 and 2.

As can be seen in FIGS. 1 and 2, Examples 1 and 2 exhibited low-viscosity liquid-type compositions, were easy to discharge into a bubble container, and exhibited abundant bubbles.

In addition, as can be seen in FIGS. 3 and 4, in Examples 1 and 2, it was confirmed that a gommage was generated when the foam was rubbed to effectively remove dead skin cells.

1-2. Preparation of Comparative Example Cosmetic Composition

Comparative Examples 1 to 7 were prepared according to the components and contents listed in Table 2 below.

division ingredient Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Comparative Example 7 polyacrylic acid carbomer 3.0 3.0 0.5 1.0 3.0 3.0 2.2 quaternary ammonium salt Steatrimonium Methosulfate 3.0 3.0 0.5 1.0 4.5 3.0 3.0 polyol PEG-8 4.0 4.0 4.0 4.0 4.0 4.0 4.0 salts sodium chloride 0.8 0.8 0.8 0.8 0.8 0.4 1.5 nonionic surfactant Cocoglucoside 1.0 8.0 3.0 3.0 3.0 3.0 3.0 solvent Purified water 88.2 81.2 91.2 90.2 84.7 86.6 86.3 Total (Unit: % by weight) 100.0 100.0 100.0 100.0 100.0 100.0 100.0

Specifically, after dissolving polyacrylic acid carbomer in purified water, it was stirred at 3000 rpm with an Agimixer to form a polymer matrix. Then, steartrimonium methosulfate, a quaternary ammonium salt, was added to the polymer matrix and mixed at 3000 rpm with a homomixer to prepare a first mixture. Then, cocoglucoside, a nonionic surfactant, and sodium chloride, a salt, were added to the first mixture, and then mixed at 2000 rpm to decrease the viscosity of the mixture, thereby preparing a second mixture. Then, PEG-8, a polyol, was added to the second mixture, mixed at 2000 rpm with a homomixer, and subjected to a defoaming process to prepare Comparative Examples 1 to 7.

As a result of the manufacture, when the content of the nonionic surfactant in the composition was appropriately adjusted, in Comparative Example 1, the content of the nonionic surfactant was added in an amount less than the appropriate amount of 1.5 to 6.0% by weight, resulting in slightly insufficient foam compared to the example. , the amount of surfactant was insufficient, and the cleansing power was poor. On the other hand, in Comparative Example 2, the content of the nonionic surfactant was added in an amount greater than the appropriate amount of 1.5 to 6.0% by weight, indicating that the stability of the formulation was broken due to the addition of an excessive amount of the surfactant.

In addition, in the case of Comparative Example in which the content of the nonionic surfactant in the composition is the same but the content of the carbomer and the quaternary ammonium salt is adjusted, Comparative Example 3 contains 0.5% by weight of the carbomer and 0.5% by weight of the quaternary ammonium salt. Gommage was not produced well when rolling on the skin because the content was lower than that, and in Comparative Example 4, the carbomer was 1.0% by weight and the quaternary ammonium salt was 1.0% by weight. Less than the examples were produced. And Comparative Example 5 included 4.5% by weight of quaternary ammonium, which was out of the range of 1.0 to 4.0% by weight, and the polymer matrix was broken, and as a result, the gel phase was separated and a stable liquid composition could not be obtained.

In addition, in the case of Comparative Example in which the content of salt in the composition was adjusted, Comparative Example 6 contained 0.4% by weight of salt, which is half of Example, so that the viscosity of the cosmetic composition could not be lowered, which made pumping in the bubble container difficult. On the other hand, Comparative Example 7 contained 1.5% by weight, which was about 1.85 times more than Example, so the formulation appeared similar to Example, but contained an excessive amount of salt, which irritated the skin.

Experimental Example 1. Evaluation of feeling of use

After applying Examples 1 and 2 and Comparative Examples 1 to 4 appropriately on both sides of the face to 30 professional female panels aged 25 to 47 years old, the foam power felt when applied according to the following evaluation criteria, peeling effect, and use Feelings of use such as aftertaste and overall satisfaction were evaluated and shown in Table 3 below.

The bubble power means that bubbles are generated abundantly when discharged from a container. The peeling effect refers to the feeling that dead skin cells are removed after use. In addition, after-use feeling means a moisturizing feeling felt after washing with water.

<Evaluation Criteria>

24 or more women judged excellent: ◎

18 to 23 women judged excellent: ○

10 to 17 women judged to be superior: △

Fewer than 10 women judged superior: X
