Description

Powder Compositions for Washing Cosmetics

The present invention relates to a powder face wash composition.

In general, the face wash is used to clean the skin by removing the waste and sebum, such as makeup and skin, which will be described in detail as follows.

Skin contaminants are classified into exogenous contamination caused by various chemicals, dust, bacteria, cosmetics, etc. in the air, and endogenous contamination caused by sebum and sebum altered matter, various excretion contained in sweat, and aged keratin. By attaching, it becomes a place where various germs propagate, and it adversely affects the health of the skin, such as losing the function of normal sebaceous membrane.

Therefore, although surfactants of fatty acid soap are mainly used to remove skin contaminants such as sebum and waste products, hypoallergenic materials may be used to reduce skin irritation as they may cause skin pulling, itching, and skin roughening during face wash. Was introduced.

The hypoallergenic material is monoalkyl phosphate, acylyl methyl taurine, sodium cocoyl cecionate, N-lauroyl beta-alanine, and the like. Low skin irritation is also estimated to be very low.

On the other hand, the development of face wash using enzymes to remove the dirt on the skin has also been made. However, in the case of containing such enzymes, it is difficult to access a formulation containing general water. In Japanese Patent Laid-Open No. 6-239735, one method of stabilizing enzymes has been proposed in which enzymes are wrapped in microcapsules of gelatin.

Such a method is difficult to apply to the face-washing powder in a way that is utilized to avoid contact with water in the liquid face wash. In addition, the powder face wash does not contain water in the contents of the product, but because the contents are moisture-containing, the titer of the enzyme gradually decreases during use, and the amount of enzyme required to remove substantial skin contaminants is It is difficult to use due to severe stimulus.

The present invention is to solve the above problems, by using a water-repellent enzyme complex to provide a powder face wash composition that provides an excellent keratin degradation effect by preserving the titer of the enzyme for a long time.

In addition, the present invention provides a powder face wash composition that can be effectively removed without skin irritation by containing mung bean extract and mannitol.

In order to achieve the above object, the powder face wash composition of the present invention contains a water-repellent enzyme complex, mung bean extract, mannitol spray-coated with a mixture of enzyme and porous silica with silicon oil and perfluoropolymethylisopropyl ether It features.

Hereinafter, the configuration of the present invention will be described in detail.

The present invention relates to a powder face wash composition containing a water-repellent enzyme complex, mung bean extract, mannitol, which will be described in detail.

The water-repellent enzyme complex is excellent in moisture resistance to preserve the activity of the enzyme for a long time, after mixing the enzyme and porous silica silicone oil and perfluoropolymethylisopropyl ether having a viscosity of 10-100 cSt at 20 ℃ Obtained by spray coating and blended at 0.001-10% by weight, preferably 0.05-5% by weight relative to the total weight.

The enzyme used in the water-repellent enzyme complex consists of one or a mixture of two or more selected from protease, papain and lipase made from Bacillus subtilis or Actinomycetes Streptomyces grisulus.

In addition, the silicone oil is one or a mixture of at least one selected from methyl polysiloxane, dimethyl polysiloxane, methylphenyl polysiloxane or octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and cyclomethicone of dodeca methylcyclohexasiloxane.

In addition, the mung bean extract to minimize the skin irritation is 0.01-20% by weight, preferably 0.01-10% by weight based on the total weight of mannitol is 0.1-70% by weight, preferably 0.1-40% by weight, the mung bean extract Let's look at in detail as follows.

Mung bean extract is an active ingredient that shows skin irritation effect. It contains bitexin and isobitexin obtained by dipping mung bean powder in 50-80% alcohol, which not only relieves skin irritation but also is caused by antioxidant activity and environmental and physical factors. Prevents aging and roughening of skin caused by harmful oxygen.

An optimal extraction method of mung bean extract is disclosed in Korean Patent Application No. 94-29258, and among the various solvents, it is most efficient to immerse peeled mung bean powder in 50-80% alcohols. The mung bean extract obtained by this method is Vitexin 0.05-0.5%, Isobitexin 0.05-0.4%, Adenosine 0.01-0.2%, Beta-Sitosterol 0.005-0.1%, Protein 2-10%, Total lipid 1-20% , Carbohydrates 10-60% and ash 5-10%.

The following is described in more detail with reference to the following embodiments of the present invention configured as described above. However, these examples are intended to illustrate the present invention, it is obvious to those skilled in the art that the scope of the present invention is not limited to these examples. Compounding amount is shown by weight%.
