The skin is divided into three layers of epidermis, dermis and subcutaneous fat tissue in order from the outside and functions to protect the human body from physical or chemical stimuli from the external environment. In particular, the skin carries about 65-70% of the moisture that the human body has, that is, it carries various biologically active substances necessary for the human body, and plays an important role in controlling the evaporation of moisture to the body to help the skin stay soft and moist. Do it. In addition, the epidermis is separated from the outside in the order of the stratum corneum, granule layer, polar layer and basal layer, the cells of the stratum corneum act like a brick and the intercellular lipids between the stratum corneum act as a mortar to form the skin barrier ( J. Invest.Drmatol. 80 (Suppl.), 44-49, 1983). The stratum corneum of the epidermis contains about 10 to 20% of water and is present at the outermost part of the human body to suppress evaporation of moisture from the outside while preventing excessive infiltration of substances from the outside. The surface of these stratum corneum is covered with a thin, natural protective film made of sebum from the sebaceous glands and sweat from the glands to prevent evaporation of moisture. In other words, you can think of it as a form in which a sponge containing a water (stratum corneum) is wrapped in a plastic wrap (natural protective film) which does not pass water. The cells constituting the stratum corneum have high concentrations of natural moisturizing factors (NMF), which are water-soluble ingredients, which help the skin to show flexibility and maintain proper moisture. The substance is not only water soluble, but effectively binds with moisture and inhibits the drying of moisture from the skin (J. Invest. Dermatol. 54, 24-31, 1970). However, artificial temperature control of cooling / heating according to changes in environment or life patterns, skin stress caused by various stresses and environmental pollution from social life, frequent face wash due to makeup habits, and natural skin aging due to age increase Due to various causes of the moisture in the stratum corneum decreases, the skin is dried, the surface is rough, and the skin loses shine and dull appearance occurs, the need for a skin moisturizer is increasing.

Conventionally, the most widely used method is to use a humectant, which has a property of absorbing water as a moisturizer, or an occlusive moisturizer that prevents evaporation of water, thereby increasing water retention in the stratum corneum. to be. Most of the humectants are polyols, and there are materials such as glycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol. However, they have a disadvantage in that they are very sticky or damp due to the inherent viscosity and physical properties of the polyol when applied to the skin. In addition, as a closed moisturizer, lipid components such as ceramide, essential fatty acids and lipid complexes were used (J. Invest. Dermatol. There is a disadvantage that inhibits and there are disadvantages inadequate for preparing a product on a transparent gel. Formulations containing lamellar liquid crystals, which have been studied until recently, are known to have excellent moisture moisturizing properties with advantages similar to the skin keratin structure, but are problematic in that they can be universally used only in specific compositions of raw materials.

Therefore, the present inventors have studied to find a substance that protects the lipid membrane between skin cells and reduces water evaporation in the stratum corneum of the skin. The present invention has been found to be used in conjunction with oil and chamomile extracts to show excellent skin moisturizing effect.
