How to tell the authenticity of pearl powder

Question 1: How to tell the authenticity of pearl powder 1. Distinguishing the authenticity of pearl powder The real pearl powder has several important characteristics, please keep in mind and pay attention to distinguish: the real pearl powder has a faint fishy smell, which is the natural taste of pearl, not the disgusting one; Generally speaking, the smell of superfine pearl powder will be heavier than that of ordinary pearl powder; The smell of nano pearl powder is heavier than that of ultra-fine pearl powder; Real pearl powder tastes slightly salty, while nano pearl powder is a bit like sugar-free milk. The taste is mellow and comfortable, and most of the shell powder is a little astringent. The real pearl powder color is white-like, that is, close to white. The colors of pearl powder from different processes will be somewhat different, some are slightly gray and some are slightly yellow, but they are definitely not that pale color or brown, and should be very soft; Basically, no real pearl powder is sold in bags of100g, 200g or even 400g. A few dollars a bag, the real pearl powder is not so cheap; The real price of pearl powder is 4 to 6 yuan/gram, which is a relatively normal price; Zhejiang, Guangdong and Guangxi are the hardest hit areas of fake pearl powder. Of course, there are also real pearl powder, but it needs to be carefully distinguished. Fake pearl powder is mostly made of shells, which is very thick and heavy to hold in your hand. Looking under the lamp, you can find the flash, and the fluidity is particularly good (pearl powder fine enough will become a piece when pinched, and it will spread like sand when thick); There are some popular methods to distinguish the authenticity of pearl powder, which are not reliable, including: adding vinegar to it to see if there are bubbles. Clarification: No matter pearl powder, shell powder and right powder, bubbles will appear if vinegar is added, so it is impossible to distinguish the authenticity of pearl powder by this method. If you are interested in further studying the reasons, you can refer to junior high school physics; With fire, pearl powder turns black. Clarification: Both shell powder and pearl powder contain a certain amount of organic matter, which will turn black at high temperature. Therefore, this method can not be used to distinguish between true and false pearl powder. Put it in the water and observe the sinking speed. The sinking speed is related to the surface tension of liquid, the hydrophilicity and density of powder surface, and also to the humidity of powder. In this test, it is basically impossible to judge what factors affect the sinking speed, so it cannot be used as a basis for judgment. Attachment: What harm does fake and shoddy pearl powder do to you? Pearl powder is a traditional beauty product, which is deeply loved by China's ancient concubines and foreign celebrities. It is a sacred product for maintenance and restoration! The effective components in pearl powder, such as amino acids, can regulate and maintain the whole body skin, promote the synthesis of new cells, make the skin smooth, delicate and elastic, and delay aging; It can also regulate endocrine, soothe the nerves and eliminate tension and fatigue! For this reason, in today's developed science and technology industry, pearl powder, as an ancient beauty product, has changed from a luxurious palace beauty secret recipe to a fashionable MM skin care treasure after years of baptism. In recent years, with nano pearl powder becoming the mainstream of pearl powder market, there are too many counterfeit "nano pearl powder" in the market, which is very popular! A sin: blocking pores and expanding pores. Many JM think that pearl powder for oral use should be selected, and it doesn't matter for external use! So when I chose pearl powder for external use, I bought a little cheaper pearl powder with poor quality ... Who knows that it is useless and unsightly for skin care after use, and even worse, it will damage and destroy the skin! I hereby seriously warn all sisters: Don't be greedy for petty gain and neglect quality! Choose a good brand and quality pearl powder for internal and external use! In fact, pearl powder for external use should be thinner and better. The skin's absorption capacity is extremely weak, and the finer the pearl powder for external use, the better it will be absorbed, so it is the best choice to use good nano pearl powder. In addition, the use of fine pearl powder can avoid damage to the stratum corneum. Real pearl powder is so demanding, let alone fake. Therefore, pearl powder for external use should not be sloppy at all. Two sins: skin abrasion and pore damage. Among all kinds of fake pearl powder, because the raw material is not 100% pearl, the fineness is not fine enough, and the finished product is often rough! The identification method is simple. You can see many bright spots in the light. If possible, you can look at it under a microscope and find many sharp water chestnuts. It smells tasteless, dry powder is on the back of the hand, and there is a tingling sensation of particles. When using this kind of thing, it is easy to wear the skin. After using this pearl powder for a period of time, the skin will be very red and thin, and some will even cause irreversible allergic reactions to the skin, and even cause pores to be injured and inflamed, resulting in rougher skin. Here, I want to remind you that there are many freshly ground pearl powders on the market ... >>

Question 2: How to distinguish the authenticity of pearl powder from its color and smell? This is an effective method. A good pearl powder should be white with a little fishy smell. The powder is even in color and contains no impurities, and it feels delicate (but not as smooth as flour, and the real pearl powder has its own unique texture). @ This pearl powder has the best effect.

Good pearl powder generally smells a faint fishy smell, because pearl is an active substance. # If there is no fishy smell, it must have been destroyed by chemical treatment. If the fishy smell is strong, there must be mussels, dead beads and yellow beads in the raw materials, so you'd better smell them before taking pearl powder. (Most of the products on the market that cost a few dollars, ten yuan or hundreds of grams are fakes, and some still contain shiny particles. This one must be made of clam shells. Such fakes can easily cause skin allergies, but greed and cheapness are not worth the candle. It is best to choose a brand. )

Question 3: Teach you a trick to distinguish pearl powder from genuine products. "The pearls are round and jade, and the powder contains spring" is a beautiful compliment to women's skin. Pearl powder beauty beauty has a good effect, but there are many fake and shoddy products on the market. Therefore, consumers should pay attention to distinguish the quality of pearl powder or buy famous brands when buying.

Pearl powder can be divided into three categories according to particle size:

1) ordinary pearl powder: the particle size is above 200 meshes, which can meet the basic requirements of the country.

2) Ultrafine pearl powder: the fineness is above 1000 mesh (or the particle size is below 15 micron).

3) Nano pearl powder: the fineness is above1.5000 mesh (or below 1.000 nm). The finer the pearl powder, the more difficult the processing technology and the higher the price, but the finer the powder, the higher the absorption rate and the better the efficacy. Such as nano pearl powder produced by Nanguang Pharmaceutical Factory in Taiwan Province Province.

The processing technology is divided into 1) natural pearl powder: it is made by physical methods (such as ball milling, airflow crushing and physical superfine powder technology), and is characterized by not adding any other substances or destroying any substances, and maintaining all nutritional components of pearls.

2) Pearl powder prepared by chemical method: mainly by enzymolysis or acidolysis, characterized by being easily soluble in water, suitable for people with gastric acid deficiency. The disadvantage is that the nutritional components are incomplete, and there are only one or several functions, so it is difficult to use externally.

High quality pure pearl powder:

The raw materials are generally high-quality freshwater pearls, which have been 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. Inferior pearl powder: texture: the main raw material of this powder is the powder drilled in the process of pearl jewelry processing, mixed with talcum powder.

Color: yellowish, mainly caused by high temperature and heat when drilling. When drilling holes in pearls, the black steel needle rotates at high speed and the temperature is very high. The metal components rubbed between the needle and the pearl will fall into the powder, which will make people chronically poisoned after long-term use.

Smell: there is a burning or smelly smell when taking it. 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. This fake pearl powder is mixed with hydrolyzed animal protein powder, and mica will stick to the stomach after long-term use.

Color: obviously whiter than pure pearl powder. Precautions for purchasing pearl powder The finer the pearl powder, the better.

The finer the pearl powder, the better, because the easier it is absorbed by the human body, the more expensive it is. Inferior pearl powder, the particles are very thick, and some are even as thick as sand. Might as well gently * * * on the back of your hand. If it feels rough, don't think about it. Because this pearl powder can't be absorbed by oral administration, it will hurt the skin (mainly the stratum corneum) for external use, which is a very serious matter. Be careful! ) It will only make you waste money.

The authenticity of pearl powder without odor can also be identified by taste. When buying pearl powder, take a small amount of pearl powder and taste it with the tip of your tongue. Pure pearl powder has no peculiar smell, mellow taste, and a faint sea smell (or fragrance) unique to pearls. If it has sour, astringent, pungent or other peculiar smell, or has no taste, don't buy it. If the powder tastes burnt or burnt and the color of the powder is yellow, these may be the residual powder collected after drilling pearls. The high-speed rotation of the black steel needle causes the powder to turn yellow, and long-term use of this pearl powder may lead to heavy metal accumulation and poisoning.

The appearance of light gray nano pearl powder is light gray. Because the particle fineness becomes smaller, the reflective ability is weakened, and the color seen by the naked eye is light gray. The appearance of fake pearl powder may be obviously whiter than real pearl powder. Take a small amount of powder with your fingers and observe it carefully in the sun or light. You may find a clear flash. This is mica powder. If pearl powder is obviously yellow or dark, it means that the texture is impure.

Manufacturers of high-quality pearl powder with exquisite packaging will pay great attention to every detail of the product. For example, the Chinese and English characters and even punctuation marks on the package will not be wrong, and the requirements for printing quality and packaging quality are very strict, and there will be no black color, inaccurate overprint and inaccurate sealing.

Qualification certification If the pearl powder you buy is a drug with the brand name of Sinopharm, then the manufacturer must pass GMP certification (which belongs to the national compulsory certification, and all pharmaceutical companies must pass it), otherwise the safety of the product cannot be guaranteed. Good companies will make pearl powder for health food according to pharmaceutical standards, and the quality requirements are very strict. Therefore, understanding the qualifications of producers is not ... >; & gt

Question 4: How to distinguish the authenticity and purity of pearl powder ..? 1. Document number: At present, there are many document numbers of pearl powder products in the market, including Zhunzi, health food, Chinese herbal pieces, food and so on. Some manufacturers promote their products according to some better document numbers, and consumers agree with this statement. Actually, this is not right. The raw material of pearl powder is a single pearl, which is made by different processes, so the document number is not the standard to judge the quality of pearl powder. The main judgment should have the following factors: 1, depending on whether there is a GMP-certified workshop. First: the price factor. The production cost of high-quality pearl powder: high-quality medicinal pearl is about 100 yuan /kg, plus packaging, equipment depreciation, management expenses, logistics expenses, etc. Therefore, high-quality medicinal pearl powder must be greater than 100 yuan. Of course, it doesn't mean that pearl powder above 100 yuan is of high quality. The price of inferior pearl powder in street stalls: it is doubtful that you can buy 200 grams or even 300 grams of pearl powder for a few yuan or more. Second: skin feeling. High-quality pearl powder: the finer the pearl powder, the better, and of course the more expensive it is. Inferior pearl powder: the particles are very thick, even as thick as sand. Identification method: gently * * * on the back of the hand. If it feels rough, don't think about it. Third: taste. Pure pearl powder: no peculiar smell, mellow taste, faint fishy smell or pearl-specific fragrance in the aftertaste. Inferior pearl powder: sour, astringent, pungent or odorless, or tasteless. If the powder smells burnt or burnt, and the color of the powder turns yellow, it may be the residual powder of the pearl diamond, and the yellowing of the powder is caused by the high-speed rotation and heating of the black steel needle. Long-term use of this pearl powder may lead to heavy metal accumulation poisoning. Identification method: take a small amount of pearl powder and taste it with the tip of your tongue. Fourth: appearance. Inferior pearl powder: obviously whiter than real pearl powder. Take a small amount of powder with your fingers and observe it carefully in the sun or light. You may find a clear flash. This is mica powder. If pearl powder is obviously yellow or dark, it means that the texture is impure. Fifth: details. High-quality pearl powder: the manufacturer will pay great attention to every detail of the product, such as packaging, Chinese and English characters and even punctuation. The requirements for printing quality and packaging quality are very strict, the color will not be black, overprinting will not be inaccurate, and sealing will not be incorrect. Sixth: related certification. Pharmaceutical pearl powder manufacturers with the quasi-brand name of National Medicine should pass GMP certification, otherwise the safety of products cannot be guaranteed. Seventh: the choice of fineness. High-quality pearl powder: the powder is delicate, easily absorbed by the human body and has poor fluidity. Identification method: Pearl powder on the market is mostly bagged. Try to pinch the bag when you buy it. If the powder quickly gets out of the way (flows) and stays away from the place where you put pressure, then even pearl powder is extremely thick. The part you pressed won't spread out so easily, or even spread out (sorry, I can't help it if the flour is wrapped in it, hehe), but it will converge into a tight ball, which shows that this pearl powder is already very thin. To sum up: fake pearl powder: texture: take a small amount of powder with your fingers and unfold it in the sun or light, 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. High-quality pure pearl powder: texture: the powder is white, with uniform color and no impurities. Handle: It feels delicate and smooth, and is easily absorbed by the skin. Smell: It smells a little fishy, and there is no other smell. 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: The smell is burnt or smelly. Black steel needle fragments fall into powder and contain a large number of metal bodies, which will make people chronically poisoned after long-term use. Eighth: Choose a trustworthy brand. Nine usages of pearl powder all say that pearl powder has beauty effect, but why can it be beautiful? How to beauty? But few people can tell. Two days ago, Xiao Yao happened to see a program about pearls on CCTV's science and education channel, and he couldn't wait to take it out and present a treasure. In fact, pearl powder alone can't achieve a good cosmetic effect. The pearl itself only acts as a conduit, sending nutrients in and then guiding impurities out of the skin. Therefore, pearl powder should be combined with other cosmetics with medicinal effects ...

Question 5: How to distinguish true and false pearl powder? How to distinguish the authenticity of pearl powder;

Generally speaking, the best pearl powder is delicate in texture and light in taste; Inferior pearl powder is the kind with strong smell and bad smell. Specifically, the real high-quality pearl powder raw material is high-quality freshwater pearls. Texture: the powder is white, uniform in color and free of impurities; Hand feeling: it feels delicate and smooth, and is easily absorbed by the skin; Smell: It smells slightly fishy, but there is no other peculiar smell. Pearl powder can be put into pure water. Good pearl powder won't sink at all, but it will fog a lot, and the dust that sinks at the bottom of the cup is like smoke. Inferior pearl powder is not like this. The main raw material of this powder is the powder drilled in the process of pearl jewelry processing, mixed with talcum powder. The yellow color is mainly caused by high temperature and high heat when drilling; When taken, it tastes burnt or smelly; Long-term use will cause chronic poisoning. Fake pearl powder can be dipped in a small amount of powder with your fingers. After careful observation in sunlight or light, there will be obvious mica, which is obviously whiter than pure pearl powder. Long-term use is extremely harmful to the gastrointestinal tract.

Simply put, the mesh number of pearl powder refers to the fineness of pearl powder. The larger the mesh number, the finer the grinding. Traditional pearl powder is made with traditional tools such as sieve.

Traditional pearl powder is made by washing pearls, wrapping them in cloth, boiling them for about two hours, taking them out, exposing them to the sun 1 ~ 2 times at night, grinding them into fine powder and drying them in the sun for later use. This pearl powder can form a suspension when poured into water, and can be dissolved in gastric acid, which not only keeps all the ingredients of pearl powder effective, but also improves the absorption rate of pearl powder. At present, a large part of pearl powder on the market is made of pearl mussel shells, and the price, quality and authenticity are quite different.

Question 6: How to identify the authenticity of pearl powder? What is the market price? Thank you, everyone. How to tell the quality of pearl powder? Choosing pearl powder is a headache and a very important thing. It is related to health and beauty. Health and beauty are important events for beautiful women. However, there are several principles for reference: First, please be careful when pearl powder is incredibly cheap. Because generally speaking, the cost price of high-quality medicinal pearls is around 400 yuan/Jin, plus processing fees, management fees, sales fees, packaging fees, other costs and reasonable profits, it is impossible to sell a bag of ten or twenty dollars. Second, if the packaging and printing are rough, the words are full of mistakes and omissions, please be alert. Every detail of a really good product from the inside out will be handled very carefully, and it is impossible to perfunctory. Third, choosing a trustworthy brand is also an effective way. Excellent factories will generally strictly control the quality, and good ones will pass GMP certification. Of course, the service will not be bad. Fourthly, predecessors have also made a lot of summaries on distinguishing between true and false pearl powder. Let's learn (from eating well): high-quality pure pearl powder: texture: look at the pink, white and even, without 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 in the process of 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. Long-term use will cause chronic poisoning. May you choose pure and high-quality pearl powder, which can not only ensure safety and effectiveness, but also give you a youthful and beautiful self.

Question 7: I bought a bag of pearl powder. How to tell good from bad? How to tell whether it is made of shells or not, and how to tell the true and false pearl powder.

Pearl powder can play the role of health care and beauty, while fake pearl powder can not only protect health and beauty, but also endanger the health of consumers because of the excessive total number of Escherichia coli. So, how to identify its authenticity? Introduction is as follows:

High-quality pure pearl powder: raw materials are high-quality seawater pearls, carefully selected and washed, produced according to drug quality standards, 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.

Also: talk about the finely ground pearl powder, which is insoluble in water (1). Appearance: cut a little pearl powder by hand, and look carefully for obvious flash. If there is, there are impurities in it. (2) Handfeel: Fine and smooth pearl powder is good and easy to attach to hands, and softness is very important to pearl powder. (3) Color: Fake pearl powder may be particularly white or yellow. Pearl white is the best color of pearl powder (4) Experiment: adding vinegar or hydrochloric acid will produce bubbles (but shell powder will also produce bubbles) (5) Taste: seawater pearl powder has a little fishy smell, fake pearl powder has a burnt or smelly smell, or other tastes (6) Origin: seawater pearl powder is mainly produced in Beihai, Guangxi, also known as Nanzhu; Freshwater pearl powder is mainly produced in Zhejiang. If it is produced in Zhejiang, it is false to say Haizhu. (7) Packaging: The packaging is too rough and may be unqualified. (8) Specification: Pearl powder produced by good manufacturers is small in size and easy to store. The large size is probably shell powder. 9) Mesh number: The minimum mesh number of pearl powder is 200, and the high mesh number is 800. More than 2000 items are fake. If water-soluble pearl powder is distinguished,

(1) is coarse because it will crystallize during hydrolysis.

(2) Soak in hot water for 10 minute, stir and dissolve in clear water.

(3) It will be marked as \ \ \ \ water soluble \ \ \ \

(4) Small-sized hardcover packaging.

Question 8: How to distinguish the purity of pearl powder on the market mainly depends on the following factors:

1, see if there is a GMP certified workshop.

2. Is the raw material pure pearls? (At present, some raw materials of pearl powder on the market are: mussel shell, pearl necklace waste, talcum powder, dead pearl, yellow pearl and shelled pearl), and it is best to have the origin mark of the raw materials.

3. The size of the company

Second, the color problem: At present, there are several colors of pearl powder on the market: 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.

3. 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 and utilized by human body, and it has been listed 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.
