Description

Cosmetic composition comprising Buah Merah fruit oil and sodium hyaluronate crosspolymer with excellent moisturizing and barrier-enhancing effects The present application relates to a cosmetic composition having excellent moisturizing and barrier-strengthening effects comprising Buah Merah fruit oil and sodium hyaluronate crosspolymer. The skin is susceptible to damage from continuous exposure to various external factors, such as ultraviolet rays, dry climates, and fine dust. These irritations accelerate moisture loss and weaken the skin's barrier function by causing cracks in the stratum corneum or the destruction of the sebum film. Consequently, the skin becomes rough and dry, and may transform into sensitive or acne-prone skin. The skin barrier acts as a protective layer that inhibits moisture evaporation and blocks the penetration of harmful external substances, playing a key role in maintaining healthy skin. Therefore, retaining skin moisture and strengthening the barrier are major challenges for healthy skin, and to address this, various products related to hydration, inhibition of moisture evaporation, and barrier restoration are being developed. Recently, there has been growing interest in cosmetic compositions capable of simultaneously achieving functional restoration of the skin barrier and moisture retention, going beyond simple moisturizing effects; accordingly, the need for the development of related products is increasing.

The structural or functional descriptions of the embodiments disclosed in this specification are merely illustrative for the purpose of explaining embodiments according to the technical concept of this application. Furthermore, embodiments according to the technical concept of this application may be implemented in various forms other than those disclosed in this specification. Additionally, the technical concept of this application is not to be interpreted as being limited to the embodiments described in this specification. Among the physical properties mentioned in this specification, if the measurement temperature affects the property, the property is the one measured at room temperature and pressure unless otherwise specifically stipulated. Unless otherwise specifically defined among the physical properties mentioned in this specification, said physical properties may basically follow the SI unit system. For example, weight may be expressed in kg units, and length may be expressed in m units. The term "room temperature" as used in this specification refers to a natural temperature that is not heated or cooled, and may mean, for example, any temperature within the range of 10°C to 30°C, for example, about 15°C or higher, about 18°C or higher, about 20°C or higher, about 23°C or higher, about 27°C or lower, or 25°C. Unless specifically defined in this specification, the unit of temperature is Celsius (°C). The term "relatively high temperature relative to room temperature" as used in this specification refers to a temperature higher than room temperature, and may mean any temperature within the range of, for example, greater than 30°C to 50°C, for example, about 35°C or higher, about 40°C or higher, or about 50°C or lower. Among the physical properties mentioned in this specification, if the measured pressure affects the physical property, unless otherwise specifically defined, the physical property is the property measured at atmospheric pressure. The term atmospheric pressure used in this specification refers to natural pressure that is not pressurized or depressurized, and typically refers to atmospheric pressure within the range of about 700 mmHg to 800 mmHg. As used in this specification, the terms a to b refer to a range between a and b, including a and b. For example, including a to b parts by weight is equivalent to including within the range of a to b parts by weight. The terms us
