What is the method to judge whether pearl powder is real or fake
|
The efficacy of pearl powder was discovered by humans very early. We all know that it can beautify and nourish the skin. It can also help to avoid the heat in summer. However, there are so many types of pearl powder on the market now that people don’t know how to choose. If you buy fakes, it will directly affect the effect of use. So what is a way to judge the authenticity of pearl powder? First, what is the best way to tell whether pearl powder is real or fake? Smell. Real pearl powder has a light fishy smell, which is the natural smell of pearls, not the kind that makes people sick; generally speaking, the smell of ultrafine pearl powder is heavier than that of ordinary pearl powder; and the smell of nano pearl powder is heavier than that of ultrafine pearl powder. smell. Real pearl powder tastes slightly salty, nano pearl powder is a bit like sugar-free milk, and tastes mellow and comfortable, while shell powder is mostly a bit astringent. Inferior pearl powder has sour, astringent, spicy or other strange smells, or has no smell at all. If there is a burnt or mushy smell when taking the medicine, and the powder is yellow in color, it may be the residual powder from pearl drilling. The high-speed rotation of the black steel needle causes the powder to turn yellow due to heat. If this pearl powder is taken for a long time, the side effects of the pearl powder may lead to heavy metal accumulation and poisoning. Second, color. The color of real pearl powder is off-white, that is, close to white. The color of pearl powder with different processes will be slightly different. Some are slightly gray, some are slightly yellow, but it is definitely not the kind of pale white color, nor the burnt yellow color, it should be very soft; What is a one-step method to determine whether pearl powder is authentic? Price. Basically, no real pearl powder is sold in bags of 100 grams, 200 grams or even 400 grams. A bag costs a few yuan or dozens of yuan. Real pearl powder is not that cheap. The production cost of high-quality pearl powder: high-quality medicinal pearls is about 100 yuan/kg, plus packaging, equipment depreciation, management fees, logistics costs, etc., so high-quality medicinal pearl powder must be more than 100 yuan. Of course, it does not mean that pearl powder that costs more than 100 yuan is high-quality pearl powder. .Liquidity. Fake pearl powder is made from coarsely crushed shells. It is extremely coarse and heavy in the hand. You can see it sparkle when you hold it under the light. It also has excellent fluidity (fine enough pearl powder will turn into lumps when you pinch it, while coarse enough pearl powder will spread out like sand). Identification method: Most of the pearl powders sold in the market are packaged in bags. When purchasing, try to pinch the bag. If the powder quickly moves away (flows) and moves away from the part where you apply pressure, then: even if it is pearl powder, it is extremely coarse pearl powder. If the area you press does not fall apart easily, or even does not fall apart at all, but instead gathers into a tight mass, it means that the pearl powder is already very fine. |
