How do you test if there is lead in a cream?

It's very simple, for example, you have to see whether your cream contains lead, take a sample, rub the cream a little on a tissue or cotton pad, and then use a sterling silver ring or an old version of a dime coin to wipe on it, if it turns black, it means that it contains lead, if it does not blacken, it does not contain lead, generally speaking, this can only detect whether it contains lead, in fact, as long as you buy regular skin care products, the lead content does not exceed the standard, there is no big problem, such as olay, although many products contain lead, but it does not exceed the standard, Especially in whitening products, lead can help the absorption of whitening ingredients, as long as it does not exceed the standard, it is OK, in addition, drinking more milk can also help to remove lead!

To give you a little way to test creams, I don't know if I specifically test lead, because there are no chemical elements to test the reaction, but the following aspects can know whether there are harmful substances, after all, it's not just lead that is harmful.

Cream: 1Put a little in a regular spoon, take the fire until it is completely burned, if there is a black residue, it is a variety of additives, the more it proves that the more additives, then put a cotton core in the spoon, light the cotton core, you will see that the water will emit black smoke, such a product is also not good.

2.Moisturizing products, a lot of them are made of mineral oil, you apply them to the paper, and after a while wipe off the excess, if it is moisturized, the paper will wrinkle, if it is made of mineral oil, you will find that it is transparent!

3.You can also squeeze the product onto an iron spoon and heat it with a fire underneath, and if it contains mineral oil, the oil will come out!

4.When the cream is canned, if it is a finished product with good filling technology and fine texture, its surface will show a uniform and smooth form, and there will be no large and small pores.

Take it to a professional place for inspection.

There is more or less lead added in cosmetics, otherwise how can we see the effect, just adding too much to our ** will hurt.

I know an easy way to do it, and it's also introduced by experts. Apply the cosmetics to be tested on your hands, and gently rub the position of the cosmetics with 18k gold jewelry (the ring is more convenient) to observe the color, if it becomes very dark, the cosmetics have a high lead content.

How to identify whether there is lead in cosmetics:

Method 1: Take a little product and put it in a transparent cup filled with water, if there is sediment at the bottom of the cup, it means that it contains lead and mercury, if there is floating matter on it, it means that it contains mineral oil, and if it sticks to the edge of the cup, it means that it contains animal oil.

Method 2: Find a silver ornament and smear the cosmetics on it, the silver ornament turns black, indicating that there is lead and mercury in the cosmetics. This method is suitable for all basic care and color dressing.

Take an appropriate amount of your usual foundation or lotion and put it in water and watch it react. Generally speaking, three things happen: stick to the rim of the cup, float on the surface of the water, and sink to the bottom of the cup. These three cases illustrate the ingredients they contain.

1 Sticking to the rim of the cup is animal oil. It is extracted from animals. Let's think about which cosmetics factory has an animal slaughterhouse next to it?

No, after killing the animals in the slaughterhouse, they pile the bones and fur aside, and when they have saved up a lot of them, they will be pulled to the cosmetics factory, who knows how long they have been piled up, and if it is summer, will those things spoil and rot? We eat spoiled things will vomit and diarrhea, ** the same, cosmetics made with spoiled things will produce allergies, and the manufacturer knows that it will be allergic, so in the manufacturing process, it will add soothing agents and desensitizers. The soothing agent is an anesthetic for the immune nerve, it will feel good at the beginning, but it will not work after a long time, beauticians know that the same brand of cosmetics will be used for 2-3 years to change the brand, what to change?

In exchange for a pacifier.

2 Floating on the surface of the water is mineral oil. Mineral oil is extracted from oil extracted underground. The first layer is used as gasoline; The second layer is leptonomic; The third layer is asphalt, which is used to pave the road.

And this kind of cosmetics is made of the second layer of lephur oil, lepton oil has a good moisturizing effect, but it is not breathable, which is like we wear a pair of leather pants in winter, and the legs are wet and impermeable, which will affect the permeability of **, and even accelerate **aging**.

3 Heavy metals, lead, mercury, etc., sink at the bottom of the cup. There are reports in the newspaper that pregnant women who give birth to children who are often used with whitening products are susceptible to cerebral palsy.

If the products you use do not stick to the rim of the cup, do not float, and do not sink to the bottom of the cup, then you can congratulate you, because you have chosen the right good thing, you can use it with peace of mind.

It can't be distinguished by the naked eye, so it can only be used for product testing.

The best way to do this is to do the experiment yourself with test strips.

The steps to test cosmetics for excessive levels of lead mercury hormones are as follows:

1. Take an idle silver ring from home and place it in the palm of your hand.

2. Take the cream and squeeze some out in the palm of your hand, or you can take other cosmetics and then prepare for the next step.

3. Apply the cream in the palm of your hand to the silver ring, if the silver ring turns black, it means that it contains serious heavy metal lead, otherwise, it means that there is none.

The steps to test cosmetics for excessive lead and mercury are as follows:

1. Take a silver ring, place it in the palm of your hand, and move on to the next step.

2. Take a piece of cosmetics and squeeze it in the palm of your hand, or you can take other cosmetics you want to test, and then test them according to the following methods. Then get ready for the next step.

3. Apply the cosmetics in the palm of your hand to the silver ring, if the silver ring turns black, it means that it contains serious heavy metals lead and mercury. Conversely, if the silver ring does not change in any way, it does not contain lead and mercury.

Take some cosmetics and drop them in clean water, if it sinks to the bottom of the water, it contains heavy metals such as lead, mercury, etc., and if it floats on the surface of the water, it means that it contains animal oil, which is not good for breathing. It is best to be able to melt in water.

Teach a trick: about lead testing in cosmetics [Share].

It's a very simple method, maybe many people already know it, but I still want to share it with you.

Purpose: To test skin care products or cosmetics for lead.

Materials: a dime coin, a blank piece of paper, skincare and cosmetics you use.

Dime Coin In order to test well, it is best to use a new one; If it's already used, wipe it down, especially the façade. The standard of cleanliness is to scratch the paper with the façade of the coin (the small side that the coin touches the table when standing on the table) without black scratches.

Test process: apply a little cosmetics on the white paper, wait for a while, wait for it to penetrate on the paper, and then scratch back and forth with the façade of the coin, if there is no change, you can preliminarily indicate that it does not contain lead, if it turns black, it means that it contains lead, the darker the color, the higher the lead content.

You can also try it with your face, use it for a while, and then stop, if your face is dry, allergic and acne, then congratulations, you have bought cosmetics that contain a lot of lead and mercury, if the above phenomenon does not occur, it is not a big problem.

Since you have no problem using so many methods, then use it with confidence.

If you try it and don't get it, you don't.

What brand of product do you use?

Tips for identifying cosmetics if they contain excessive lead mercury:

1. Take out a little skin care products, apply them on a piece of white paper, or a thin plastic film, and put them in the sun (or natural environment), if they turn black, it means that the skin care products may contain excessive lead.

Q: Is it true that some people try to apply foundation by putting it on hand and then applying it with a coin, and there is a black line that means it contains a lot of lead?

Niu Er (ten years of experience in professional makeup teaching, currently a lecturer in the Department of Cosmetics Application of Taiwan University of Science and Technology, strengths: **repair, cosmetics R&D and production): In fact, if you can scrape the black line, it can only be said that the color pigment of this product is used more.

Basically, the pigment is a compound of iron oxide, and the iron oxide will show its color, and rubbing it with a coin will generate heat, and the iron oxide will produce chemical changes and turn black, but this does not mean that the quality of this product is not good. Because lead was banned as early as 1913.

Q: So just a test to determine if there is a lot of pigment?

Niuer: That's right. Q: It is often said that there is a fear of mercury and lead, why is it true?

Niu Er: In the past, it was very dangerous for women to maintain themselves, for example, in the Roman and Greek eras, they used lead powder, and in China, they ate arsenic to make their faces white, and as a result, they produced toxins, which may cause rotten teeth and poison the body. And as early as the beginning of the twentieth century, after the development of medicine, it was ordered to ban these toxin raw materials.

Q: Is it okay to rub more pigment on my face?

Niuer: Pigments mostly indicate that there is enough coverage, such as vermicelli, which is more promising. Powder, on the other hand, has less coverage.

Therefore, it is wrong to use a coin to scratch a coin on a cosmetic product to test for lead!! Everyone has paid attention, Ah A simple coin to deny a brand of cosmetics really has no scientific basis, and it is very unfair, if you really want the Quality Inspection Bureau to do that? You can test it yourself

Personally, I think that as long as you do a good job of removing makeup, it will be good to have big-name cosmetics (**) come nonsense.

Therefore, the method of using coins is wrong, but there is a way to use lipstick: lipsticks contain lead, and lead is very harmful to the human body, so when choosing lipsticks, try to find those that contain less lead, and the less the better. However, how do you know how much lead is in your lipstick?

Here's one of the easiest, most convenient and accurate ways for you to use, that is: when buying lipstick, rub a sample of lipstick on the back of your hand, and then rub it with a gold ring, and observe the color change of the lipstick while grinding, the lipstick turns black indicates that the lipstick contains lead, the darker the black, the greater the lead content.

Cosmetics can be put into a stainless steel spoon, and then burn the bottom of the spoon with fire, cosmetics will evaporate, and general cosmetics will leave black or yellow marks after burning, indicating that they contain lead, and pure plants will not have this phenomenon. Learned. Good boy!

Learn to learn what are the best products to shrink pores now? This method is very effective, let's try it. Excuse me, cosmetics that contain lead are used for purpose to test whether there is lead in skin care products or cosmetics Materials prepare a dime coin, a blank piece of paper, skin care and cosmetics you use ps a dime coin - in order to test well, it is better to use a new one; If it has been used, wipe it clean, especially if the façade is clean, the standard is to use the façade of the coin (the coin is standing.
