How to detect excessive lead in cosmetics in shopping malls

I read an experiment in the magazine "Women's Square" to test cosmetics, saying that if some cosmetics are dropped in clean water, if it sinks to the bottom of the water, it means that it contains heavy metals such as lead and mercury, and if it floats on the surface of the water, it means that it contains animal oil, which is not good for breathing. Being able to melt in water is the best way to teach: about the lead content test in cosmetics [Share] A very simple method, many people may have known it for a long time, but I still want to take it out and share it with you.

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

A dime coin, a blank sheet of paper, the skincare and makeup 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.

Bring a silver bracelet and apply makeup to it, if it turns black, it will be excessive.

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.

2. Smear 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 amount of lead.

3. 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 and mercury, and if it floats on the surface of the water, it means that it contains animal oil, which is not good for breathing, and it is best to melt in water.

The methods for detecting cosmetics with excessive lead and mercury are as follows:

Take an appropriate amount of the foundation or lotion you usually use in water and observe how it reacts. 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. What sinks at the bottom of the cup is heavy metals, lead, mercury, etc., that is, lead and mercury exceed the standard.

1. Go to a special inspection agency for testing.

2. When buying lipstick, apply the lipstick to the back of your hand, rub it back and forth with silver jewelry, and observe the change of lipstick color while rubbing, the lipstick turns black to indicate that the lipstick contains lead, the darker the color, the greater the lead content.

3. Take out some cosmetics and smear them on white paper, wait for a period of time, wait for it to penetrate on the paper, and then use coins or harder metal products to scratch back and forth on the paper. If it turns black, it means that it contains lead, and the darker the color, the higher the lead content.

4. Prepare a transparent water cup, pour some water, take out some cosmetics and place them in the cup. If there is sediment at the bottom of the cup, it indicates that the cosmetic product contains lead and mercury; If there are floating objects on the water, it indicates that the cosmetic species contains minerals; If it sticks to the rim of the cup, it contains animal oil; It is best to be able to completely melt in water.

5. Take out some cosmetics and apply them on white paper, or on a thin plastic film, and place them in the sun.

6. If the silver jewelry becomes black, there is lead and mercury in the cosmetics. This method is suitable for basic care and make-up.

Before using a cosmetic product, try it on the back of the hand or the root of the ear, these two parts are the most sensitive areas of the human body, and after applying evenly, rub the silver ring (other silver products can also be replaced) on the application area a little harder, if it is black or has light black marks, it means that it contains heavy metals such as lead, and there is no need to worry.

Lipsticks contain lead, so try to find those that contain less lead when choosing lipsticks, and the less the better. However, how do you know how much lead is in your lipstick? The same can be judged in this way:

When buying lipstick, rub a sample of lipstick on the back of your hand, then rub it with a silver 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.

Methods for testing cosmetics for lead.

Clear water, gold and silver jewelry.

It is more reassuring to go to the inspection agency designated by the Ministry of Health for testing.

Apply makeup to the back of your hand, slide it on your hand with pure gold jewelry, and if it appears black, it means that it contains lead and mercury.

Take some cosmetics and apply them to silver jewelry, and the silver jewelry turns black, indicating that there is lead and mercury in the cosmetics.

Take some cosmetics and put them in a cup of water, if there is sediment at the bottom of the cup, it means that it contains lead, mercury, etc.

Apply some lipstick to the back of your hand and rub it back and forth with gold jewelry, at which point the lipstick turns black to indicate that it contains lead mercury.
