The present invention relates to a ceramide stabilized cosmetic composition containing a multi-layered nano-gel emulsion and a process for producing the multi-layer nano gel emulsion. The ceramide stabilized cosmetic composition of the present invention is characterized in that an oil-in-fat portion is mixed with stirring and then an oil portion is added to improve the water-solubility of various ceramides and derivatives thereof, which are poorly soluble skin lipids, And then the component of the aqueous phase containing the emulsifier having strong self-associating properties and the polymer capable of hydration coating at the interface with the sol-gel property according to the temperature was optimized, By stabilizing the content of ceramide up to 20% by weight and emulsifying it into multi-layer nano-gel, it is possible to easily formulate into cosmetics without desorption, and ceramides can be effectively penetrated into the skin cell interstitium, restoring damaged skin barrier, Of course, atopy is also effective in preventing skin problems. |
