Description

Pore-minimizing cosmetic composition containing Kaolin

The present invention relates to a pore-shrinkable cosmetic composition comprising kaolin as an active ingredient, and more particularly, by absorbing sebum in the pores by using kaolin, which has excellent absorption and oil absorption ability and excellent breathability, to prevent pores from widening and shrinking. It relates to a pore shrinkage cosmetic composition that can be.

The most important function of the skin is to protect the human body from external physical and chemical factors. These skins have oil glands called sebaceous glands, from which sebum is secreted and discharged through the pores to the skin surface. The sebum discharged in this way prevents the evaporation of water from the surface of the skin and protects the human body from bacteria.

The skin is divided into the outermost layer, the epidermis, the dermis and the subcutaneous fat layer, and at the bottom of the epidermis is the basal layer (Keratinocyte), where cell differentiation continues, and the differentiated cells are eliminated through the stratum corneum, the granular layer and the dead cell stratum corneum. This process is usually repeated every 28 days. If this cycle does not progress smoothly, the stratum corneum thickens and the skin becomes rough. In the periphery of the pores, these keratin blocks the entrance of the pores and secreted sebum does not go out, but it hardens in the pores and develops into acne through whiteheads and blackheads, and is also infected by purulent bacteria. This repeated pore trouble affects the dermal layer around the pores, causing the pores to widen.

Therefore, it is also important to remove the dead skin cells covering the pores and to restore the pores by smoothing the metabolism of the cells around the pores in order to shrink the pores and prevent the pores from expanding. It is important to stop losing.

Therefore, the inventors of the present invention to reduce the enlarged pores and to prevent pores widening to develop a cosmetic that can make the skin more clean and fine, while using the kaolin with excellent absorption and oil absorption ability and breathability while sebum in the pores The present invention has been completed in view of the fact that the pores can be prevented from being widened and reduced by adsorption.

Accordingly, an object of the present invention is to provide a pore-contracting cosmetic composition and a method for producing the same, which reduces the enlarged pores and prevents the pores from expanding by removing sebum in the pores by using kaolin having excellent absorption and oil absorption ability.

The present invention is 10 to 80% by weight of kaolin, 0.1 to 10% by weight of emulsifier, 0.1 to 10% by weight of polyhydric alcohol, 0.1 to 10% by weight of higher alcohol, 0.1 to 10% by weight of higher fatty acid, 1 to 40% by weight of oil and the balance It is characterized by providing a pore shrinkage cosmetic composition comprising a purified water and a preparation method thereof.
