What is the fineness of pearl powder? Is the larger the value, the better?

Recently, many Taobao friends asked me questions about pearl powder, including identification. Then I'll talk about the inside story of pearl powder market here.

Don't waste money, beware of shell powder pretending to be pearl powder. In the current pearl market, the market price of freshwater pearl medicinal beads is 50- 100 yuan per 500 grams. Pearl powder needs to be deeply processed with pearls, so it is impossible for pearl powder to be a few dollars per 500 grams. In fact, there are some leftover materials such as buttons and carvings made of mother-of-pearl shells, and some conch shells that have been frozen, heated and weathered on the beach for hundreds of years all the year round, and there is no cost at all. Is this 100% pure pearl powder? This is chicken feed. This fully proves that "there will be no pie in the sky, and there will be no free dinner underground".

Those pearl powders with hundreds of thousands of meshes can be screened out by 1000 mesh, and half of them are on the surface. So you can calculate the price of pearl powder per gram by yourself.

In addition, I'll teach you a good way to identify the thickness of pearl powder. Just put a little pearl powder in a thin plastic bag and rub it with your fingers, and you can see that the thick one has a sandy feeling, while the thin one is slippery above 1000 mesh.

High quality pure pearl powder:

The raw materials are high-quality freshwater pearls, which have been carefully cleaned, produced according to the quality standards of drugs and passed the inspection.

Texture: the powder is white, uniform in color and free of impurities.

Handle: It feels delicate and smooth, and is easily absorbed by the skin.

Smell: It smells slightly fishy, but there is no other peculiar smell.

Fake pearl powder:

Fake pearl powder is generally made by heating mussel shells with alkaline water and lime, then removing the black on the surface, crushing, sieving and packaging.

Texture: take a small amount of powder with your fingers, spread it out in the sun or light and observe it carefully, and you can find obvious flash. This is mica.

Color: obviously whiter than pure pearl powder.

This fake pearl powder is mixed with hydrolyzed animal protein powder, and mica will stick to the stomach after long-term use.

Inferior pearl powder:

Texture: The main raw material of this powder is the powder drilled during pearl jewelry processing, mixed with talcum powder.

Color: yellowish, mainly caused by high temperature and high heat during drilling.

Smell: there is a burning or smelly smell when taking it.

Black steel needles drill holes in pearls by heating and rotating, and the fragments of black steel needles fall into powder, which contains a large number of metal bodies, which will make people chronically poisoned if taken for a long time.

Pearl color: There are several colors of pearl powder on the market at present: snow white, smoke gray, light yellow, white-like and so on. Let me help consumers analyze the source of these colors:

1, Snow White: This kind of pearl powder is generally chemically treated, which destroys the natural ingredients of pearls and has a certain discount on the efficacy of human body.

2. Smoke gray: The main reason for this pearl powder is that it is sterilized by strong irradiation in the factory. Its biggest disadvantage is that it destroys the active ingredients of pearl, which has little influence on the biochemical reaction in human body and has great influence on the effect of pearl powder.

3. Yellow: This pearl powder has colorful mother colors in the sun, mainly because the raw materials are impure. Generally, it is mussel shell, pearl necklace waste, dead beads, yellow beads, shelled beads and so on. Consumers are advised not to take this pearl powder.

4. White-like: This pearl powder is a good pearl powder. It smells a little fishy, with uniform color, no impurities and delicate touch. This pearl powder has the best effect.

Pearl fineness: At present, the fineness of pearl powder on the market is roughly: 1000 mesh, 2,000 mesh, 5,000-10000 mesh, nanometer. From the point of view of human absorption, 2000- 10000 mesh can be completely absorbed by human body, and there are many pearl powders on the market at present. In fact, at present, there are almost no manufacturers in China who can achieve the real nanometer level. Moreover, from the point of view of human absorption, 2000- 10000 mesh pearl powder is enough, which is too fine and wastes resources and money from a certain point of view.
