Description

TECHNICAL FIELD The present invention relates to a cosmetic composition containing moisturizing complex,

The present invention relates to a cosmetic composition for moisturizing the skin, and more specifically to a cosmetic composition for moisturizing the skin, which comprises a hydrogelylated lecithin, polyglyceryl-10 stearate, an ester oil, glycerin, shea butter, evening primrose oil, ceramide, tocopherol, hyaluronic acid, And a moisturizing complex comprising extract, hydrolized collagen, manuka honey, and yam root extract as an active ingredient, and having excellent skin moisturizing effect.

The skin is divided into three layers: epidermis, dermis, and subcutaneous tissue. The double epidermis is a fatigue-keratinized state in middle layer, the inner dermis is a tight connective tissue, and the subcutaneous tissue inside the dermis serves to fix the skin to the inner organs. In particular, the epidermis is the thinnest layer of the three layers and plays an important role in skin moisturization and protection. The epidermis consists of a seed layer (basal layer, polar cell layer), a granular layer, a transparent layer and a stratum corneum from the inside to the outside. The outermost stratum corneum constitutes 50% of keratin, 20% of fat, 23% of aqueous solution and 7% of water. Thickness of stratum corneum varies depending on the state of water content of stratum corneum, It is necessary to contain moisture of 10% or more in order to maintain elasticity of the stratum corneum.

Recently, due to various industrial pollution and various social factors such as environmental pollution and various stress factors, damage to the stratum corneum and the lipid layer has been increased and the transdermal water loss has been rapidly increased, .

Generally, a method of increasing the moisture retention in the stratum corneum is widely used by using a humectant having a property of absorbing moisture as a humectant and an occlusive moisturizer preventing evaporation of water. Examples of the moisturizing component include polyols such as glycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol and the like, and lipid components such as ceramides and essential fatty acids and lipid complexes are used as the sealing components (J. Invest. Dermatol (5), 731-740, 1994).

These moisturizing ingredients have a disadvantage in that the moisturizing effect is temporary so that they can not maintain long-term skin moisturizing effect or are difficult to apply to various formulations.

The inventors of the present invention have studied a cosmetic composition which can keep skin moisturized while keeping a large amount of moisture on the skin. As a result, it has been found that the skin moisturizing effect is maintained for a long period of time when the composition is used as a complex containing moisturizing ingredients in a specific amount, Thus completing the present invention.

Korean Patent Publication No. 10-2008-0088735 (2008.10.06) Korean Patent Publication No. 10-2008-0046983 (2008.05.28)
