Powder cosmetics equipment need to go through what process

2019-07-18
Powder cosmetics are cosmetic cosmetics used for the face, and its function is to apply very fine particles of powder to the face to cover some defects on the skin, requiring a nearly natural complexion and a good texture. Cosmetic equipment manufacturers powder products should have good smoothness, adhesion, absorption and hiding power, its aroma should be fragrant and not rich, so as not to mask the fragrance of perfume. According to the requirements of use, powder products should have the following characteristics: smoothness: powder raw materials often have a tendency to agglomerate and agglomerate, and when the powder is applied to the face, it is easy to drag, so it must have smoothness to keep the powder flowing.

According to the requirements of use, powder products should have the following characteristics:
Slippery: powder raw materials often tend to agglomerate and agglomerate. When the incense powder is applied to the face, it is easy to drag. Therefore, it must be slippery to keep the incense powder flowing. The slipperiness of powder products is realized by the action of talcum powder. There are many kinds of talcum powder, its color is soft and smooth, some rough and hard. The quality of the main raw materials such as talcum powder to make careful choice is the key to the success of the manufacture of powder products. Talcum powder suitable for powder products must be very white, odorless, soft and smooth on the fingers, because the particles of talcum powder have a smooth surface, and the friction between the particles is very small. High quality talcum powder can give the powder a special translucency, can adhere to the skin evenly.
Adhesion: powder products most avoid falling off after coating, so it is required to adhere to the skin. Magnesium stearate, zinc and aluminum salts have good adhesion on the skin and can increase the adhesion of powder on the skin. This kind of stearic acid metal salt or palmitic acid metal salt is often used as the adhesive agent of fragrance powder. The relative density of this metal salt is small, white and odorless. Magnesium or zinc salt is often used in powder products, aluminum stearate is rough, and calcium stearate is lack of smoothness. Zinc undecylenate also has good adhesion, but the cost is higher. The metal salts of stearic acid are light white fine powder, and the powder products are wrapped outside other powder particles to make the powder difficult to penetrate water. The amount of adhesive is determined according to the needs of the formula, generally in5%-15%。
Absorbency: Absorbency refers to the absorption of perfume, but also refers to the absorption of oil and moisture. Powder products are generally precipitated calcium carbonate, magnesium carbonate, gelatinous clay, starch or diatomaceous earth as the flavor of the absorbent. The absorption of calcium carbonate is due to the fact that the particles have many pores. It is a white matte fine powder, so it has the same effect as the adhesive clay to eliminate the flash of talcum powder. The disadvantage of calcium carbonate is that it is alkaline reaction. If it is used in powder products and applied in hot days, stripes will be formed on the skin after sweat absorption. Therefore, the amount of calcium carbonate in powder products should not be too much, and the amount is generally not more15%.
Covering power: powder products generally with color, close to the color of the skin, can cover chloasma or small defects. Commonly used white pigments are zinc oxide and titanium dioxide. These raw materials are called"Covering agent", the hiding power is expressed by the black surface that can be covered by the covering agent per unit weight. For example, 1kg of titanium dioxide can cover about 12 square meters of black surface. 15%-25% zinc oxide is used in the formula, which can make the powder products have sufficient hiding power without being too dry to the skin. If better hiding power is required, zinc oxide and titanium dioxide can be used together.
