Description

Gommage type cosmetic composition for makeup removal and exfoliation {GOMMAGE TYPE COSMETIC COMPOSITION FOR REMOVING MAKEUP AND EXFOLIATING}

The present invention relates to a gommage-type cosmetic composition that can simultaneously achieve makeup removal and exfoliation effects.

The stratum corneum of the skin is composed of 10 to 20 layers of dead cells, intercellular lipid, and natural moisturizing factor (NMF) that exist in the outermost layer of the skin. This stratum corneum protects the skin from various external pollutants such as dust, ultraviolet rays, and harmful substances, and at the same time prevents the loss of skin moisture.

In general, in healthy people, the exfoliation and production of the stratum corneum repeat every four weeks. However, due to external factors or internal factors such as aging, the exfoliation and production of the stratum corneum do not repeat evenly, and the stratum corneum accumulates. In this case, skin tone becomes dull or uneven, and problems such as skin keratinization occur.

Accordingly, various types of cosmetic compositions are being developed for removing dead skin cells by chemical or physical methods. For example, the chemical method uses AHA (Alpha hydroxy acid), BHA (Beta hydroxy acid), salicylic acid, and extracts of natural products with an exfoliating effect to dissolve and remove dead skin cells or promote exfoliation and creation of the stratum corneum. tell the way However, the chemical method had problems in that skin irritation occurred due to ingredients having a low pH, and side effects such as skin allergies occurred due to certain ingredients.

As an alternative to the chemical method, the use of a physical method is gradually increasing, in which a cosmetic composition in the form of a cream or gel formulation containing granules is applied and rolled on the skin to remove dead skin cells from the skin surface. In the case of this physical method, the problem of skin side effects is reduced compared to the chemical method, but there is still a problem of skin irritation caused by particles in the form of particles.

Accordingly, in recent years, there has been active development of cosmetic compositions for removing dead skin cells of the Gommage type, which is a type of the physical method.

In the case of the gommage type, in the process of applying and rolling the cosmetic composition to the skin, the contents are pushed out like dirt, adsorbing and removing dead skin cells and wastes on the skin surface, compared to the case containing particles in the form of particles. , it has the advantage of being soft, maintaining moisture on the skin, and causing less skin irritation. For example, in Korean Patent Publication No. 10-2021-0049609, polyol; Surfactants; Gelling agents including sodium stearate, sorbitan oleate, 12-hydroxystearic acid, hydrogenated castor oil, octadecyl stearate, ethylene glycol ester, propylene glycol ester, sorbitol fatty acid ester, etc.; cellulose; and a dispersant; and a gommage type cosmetic composition for removing dead skin cells.

Meanwhile, most cosmetic compositions for exfoliation, including the disclosed patent, do not take into account the fact that they remove dead skin cells and makeup from the skin at the same time, causing the inconvenience of users having to remove makeup and exfoliate separately. There was a feeling.

Accordingly, in recent years, various attempts have been made to remove makeup and dead skin cells at the same time, but it is difficult to form a cosmetic composition for removing makeup using a high content of oil into a gommage type with a stable formulation, so it is difficult to use and Development is minimal.

Republic of Korea Patent Publication No. 10-2021-0049609
