Manufacturing method of white cosmetics using high temperature drying {Powder Toiletry of Manufacture-method}

1 is a flow chart showing a step of manufacturing a white fraction cosmetics using high temperature drying according to an embodiment of the present invention.

The present invention relates to a method for producing a white powder cosmetic using high temperature drying. More specifically, magnesium aluminum silicate is mixed into a powder, an O / W emulsion is sprayed with a binder and kneaded with water, and then dried at high temperature after molding. By solidifying, the breakage and powder of powder is reduced, the stability is increased accordingly, and the content of pearl pigment can be dramatically increased, and the powder can be molded into a dome type cosmetic powder manufacturing method using high temperature drying. It is about.

In general, make-up cosmetics on solid cakes that compress and compact powders such as eye shadows, blushes, and compacts are generally manufactured. This is a method of mixing an oily binder with powder and compressing the powder using a press. Although there is a difference, conventionally, there is a possibility of being damaged by dropping during the use of the product due to weak physical impact.

Thus, if the pressure is used to improve the stability, the contents do not adhere to the brush or puff relatively well. On the contrary, if the pressure of the press is lowered and molded to improve the feeling of use, it is easily broken.

In particular, when a large amount of a pearl pigment having a plate-like structure such as eye shadow or blusher is contained in proportion to its content, the stability against impact deteriorates and the pearl pigment is limited in quantity. At this time, the conventional compression molding method is limited in its molding shape, such as forming a flat surface or forming only some bends in order to make the contents evenly compressive load.

In addition, the pearl pigment is pulverized while the impeller of the mixer rotates at a high speed during the mixing process with the binder during the manufacturing process of the product in which the pearl is mixed, resulting in a weaker than the original pearl strength.

Accordingly, the present invention has been made to solve the above conventional problems,

Magnesium aluminum silicate is mixed into the powder, the O / W emulsion is sprayed into the binder and then kneaded with water, and it is dried at a high temperature and then solidified to reduce powder breakage and powder blowing, thereby increasing stability and pearl The content of the pigment can be significantly increased, and the powder can be formed in a dome shape.

The present invention has the following features to achieve the above object.
