Description

Mucous cleansing cosmetic composition and the method for washing skin using the same

The present invention relates to a mucus cleansing cosmetic composition and a method for washing the skin without irritation using the same, and more specifically, kaolin, sodium polyacrylate (SODIUM POLYACRYLATE), glyceryl stearate SE (GLYCERYL STEARATE SE) ), bentonite, sorbitan olivate, sodium chloride (SODIUM CHLORIDE) and hydroxyethyl cellulose (HYDROXYETHYLCELLULOSE) as active ingredients As a mucus cleansing cosmetic composition comprising as active ingredients, A mucus cleansing cosmetic composition with excellent keratin regeneration and skin moisturizing power after use while efficiently removing not only foreign substances attached to the skin, but also sebum, whiteheads and blackheads embedded deep in the skin without irritating the skin due to its improved adsorption ability, and skin sebum, It relates to a method for removing whiteheads and blackheads without skin irritation.

In modern society, as interest in appearance increases, the importance of skin is being emphasized more and more. Economic prosperity, the development of mass media and the accompanying popular culture have heightened interest in skin beauty, and as a result, interest in skin care is increasing.

The skin is the largest organ in the body and is largely divided into three layers, epidermis, corium, and subcutaneous fat, in order from the outside. It serves to protect against In social relations, the skin of the human body plays a very important role not only as a physiological function to protect and maintain the body, but also as a medium for expressing health and beauty.

The most basic of facial care is skin cleansing, that is, face washing. Oily contaminants such as excess sebum, cosmetics and makeup products, especially the residues of waterproof products, accumulate on the skin and clog pores and cause skin troubles, so daily skin cleansing is very important. Cleanser removes various wastes such as sweat, sebum, dust, and aged dead skin cells, makeup residues, and other contaminants from the skin surface to keep the skin moist and healthy, resulting in better makeup. If the above impurities remain on the skin, capillaries contract, blood circulation is weakened, pores are clogged, and oxygen and nutrients necessary for metabolism are disturbed, making the skin unhealthy, and keratinization is more severe. Acne, pimples, blemishes, etc. appear, and lipid peroxide accumulates, which can lead to premature aging. Therefore, it is essential for skin cleansing products (cleansing agents) to have excellent cleansing power and skin protection against various skin contamination.

The stratum corneum of the skin consists of proteins, fats, water-soluble substances and water. Skin cells growing in the skin form keratinocytes as they rise to the stratum corneum, and repeat generation and exfoliation. This process is called turnover. If the turnover of dead skin cells and the removal of dead skin cells are not performed in a normal cycle due to aging and external stimuli such as UV rays and stress, hyperkeratosis occurs. In the stratum corneum where hyperkeratosis has occurred, the skin tone is not uniform, the skin looks rough and dull, and the makeup is uneven. In order to solve these problems, various cosmetic compositions for exfoliation have been developed.

Existing methods for exfoliating dead skin cells are divided into chemical methods and physical methods. As a chemical method, there is a method of dissolving and removing dead skin cells using an organic acid chemical. The organic acid chemical used for conventional exfoliation is alpha hydroxy acid (AHA, alpha hydroxy acid) or beta hydroxy acid (BHA, Beta). hydroxy acid) and the like. On the other hand, in Korean Patent Registration No. 10-1120660, a cosmetic composition containing alpha-hydroxy acid and an ether-based surfactant includes alpha-hydroxy acid, an ether-based surfactant, a water-soluble polymer material, and an amino acid-based anionic surfactant. Although a cosmetic composition with excellent exfoliating effect has been disclosed, when such an organic acid or an organic acid derivative is used, it exhibits activity at a low pH, thereby causing skin irritation or chemical skin side effects.

In addition, as a method of physically exfoliating dead skin cells, there is a method of physically exfoliating the keratinocytes using an organic powder or an inorganic powder, or an aqueous gel-forming polymer. However, even in this case, it is a method of massaging depending on the size of particles of organic or inorganic powder, and there is a problem in that the physical stimulation is strong and the pores are damaged.

Common cleansing cosmetics are manufactured in formulations such as foam, powder, cream, lotion, and oil, but these formulations do not have high adhesion to the skin, so there is a problem in that sebum, whiteheads, blackheads, etc. embedded deep in the skin are not removed well. Therefore, by applying a physical force to remove sebum, whiteheads, blackheads, etc. deeply embedded in the skin, there is a problem that the skin is greatly stimulated at this time, rather, skin troubles occur.

Therefore, the present inventors solve the above problems while removing foreign substances attached to the skin as well as sebum, whiteheads, blackheads, etc. embedded deep in the skin without irritation to the skin, and develop a cleansing cosmetic composition with excellent keratin regeneration and skin moisturizing power after use.
