The fluorescent agent in the clothes can be absorbed

There is such a possibility.

Hello, glad to help you with your answers.

Fluorescent brightener is a fluorescent dye and a complex organic compound whose characteristic is that it can produce blue fluorescence, which can make the substance visible to the naked eye very white.

Test whether ** contains fluorescent brightener, open the package of **, and then put it under the "ZF-C three-purpose ultraviolet analyzer", use ultraviolet light** to see if it will emit bright blue light, if so, indicate that ** contains fluorescent agent. If you don't have an ultraviolet analyzer, you can use an ultraviolet flashlight, an ultraviolet money detector pen, etc.

Fluorescent-containing ** shows a very large area of bright blue when irradiated with ultraviolet light. If you come into contact with the liquid slightly, it will adhere to the fluorescent agent, and if you take it, you will also have fluorescence. After rinsing your hands with water three times, the fluorescent agent on your hands still emits a strong bright blue light under ultraviolet light, and it is almost not washed off.

Switch to hand sanitizer 3 times, and after irradiation, your hands also emit blue light, but the effect is slightly better than that of clean water. Washing with a facial cleanser is almost as effective as a hand sanitizer, but it does not completely remove the fluorescent light that remains on your hands.

Harm of fluorescent agents to the human body:

Fluorescent agents are not as easy to be decomposed as general chemical components, but accumulate in the human body, producing many harmful effects and greatly reducing human immunity; Fluorescents bind to proteins outside the wound and can also hinder wound healing; Fluorescent agents can cause human cells to have a tendency to mutate, and their toxicity accumulates in the liver or other important **, which can become a potential carcinogenic factor. Cause damage to the blood system: chemical substances are easy to pollute human blood, although blood has a certain self-purification ability, trace amounts of harmful substances into it, will be diluted, decomposed, adsorbed and discharged, but long-term, a large number of toxic substances poured into, will cause qualitative changes; When it enters the blood circulation, it will damage the cell membrane of red blood cells, causing hemolysis.

It's true that clothes contain fluorescents.

Fluorescent, also known as fluorescent brightener, is a fluorescent dye, or white dye, that is also a complex organic compound. Its characteristic is that it can absorb incident light and produce fluorescence, so that the dyed substance can obtain a sparkling effect similar to glowstone, so that the substance seen by the naked eye is very white, and the effect of whitening is achieved.

Its function is to convert the invisible ultraviolet radiation absorbed by the product into violet-blue fluorescent radiation, which is complementary to the original yellow light radiation to become white light, and improve the whiteness of the product in sunlight. Brighteners have been widely used in textiles, papermaking, laundry detergents, laundry detergents, soaps, rubber, plastics, pigments and paints.

As a fluorescent brightener, its molecules have a planar conjugation system formed by electrons, and the structure is as follows: -c=c-c=c=c-c- or -n=c-c=n-c=c=c-, and after the two types of structural compounds absorb ultraviolet rays, the electrons are excited from the ground state to the active state, and return to the ground state in a very short time, which can emit fluorescence with a wavelength of 420-450nm.

According to the 359 fluorescent brighteners included in the "Dye Index" in 1982, FWA with certain practical value can be divided into five categories according to the chemical structure: stilbene type, coumarin type, pyrazoliline type, benzoxazole type, and dicarboximide type.

It's true. When it comes to the effects on the human body, fluorescent agents are also controversial, although they do contain benzene rings in their molecular structure, but studies have shown that the toxic effect of such substances is weak, there is no hormone-like effect, and there is no complete data to prove that it can cause cancer.

However, as an organic substance with a complex structure, its structure is not easy to decompose, and it may accumulate in the human body, which will cause some effects on the human body. As a common additive, as long as the dosage of the additive meets the regulations, it will still bring a good visual experience to our lives.

Fluorescent brighteners will also be added to laundry detergents, because the fluorescent brighteners in the clothing fabrics will be lost during wearing and washing, resulting in the yellowing of white clothes and the loss of colored clothes in colorful clothes.

As long as it is cotton, it does not contain fluorescents. Only chemical fiber products will contain fluorescent agents. So try not to wear chemical fiber products.

Really, and there are all sorts of them.

The fluorescent agent on clothing can be washed off. Fluorescent agent, also known as fluorescent brightener, is a fluorescent dye. The fluorescent agent in white and brightly colored clothes will be lost in small amounts with each wash, and by the time the clothes start to yellow, the original fluorescent agent is almost gone.

Therefore, some soaps, laundry detergents, and laundry detergents will add fluorescent brighteners to maintain the color of clothes.

The characteristic of the fluorescent agent is that it can absorb the incident light and produce fluorescence, so that the dyed substance can obtain a sparkling effect similar to glowstone, so that the substance seen by the naked eye is very white, and the effect of whitening is achieved.

Brighteners have been widely used in textiles, papermaking, laundry detergents, laundry detergents, soaps, rubber, plastics, pigments and paints.

For the exact toxic effect of fluorescent agent on the human body, there is not enough test data at home and abroad to support, China's health workers have studied the phototoxicity, photosensitivity and mutagenicity of fluorescent brightener FWAS (diaminostilbene fluorescent brightener) in toilet paper, and its phototoxicity, photosensitivity and AMES test results are negative, that is, there is no positive effect.

There is currently no evidence that the fluorescent brightener FWAS is phototoxic, photosensitive, and mutagenic, so there is no need to panic!

So what started the discussion about the dangers of fluorescent agents and caused panic may have something to do with commercial competition.

There must be, and there are many harms. According to the test results provided by Lanhe laboratory, it is recommended that if the fluorescent light is bright blue under the illumination of fluorescent detection lamp, it contains fluorescent agent, and if it is displayed as purple light, it does not contain it. If it contains fluorescent agents, it is *** and is a carcinogen at the same time.

Detect the presence of fluorescent agents on clothing.

Methods: visual identification, ultraviolet light.

Flashlight, money detector irradiation, special department testing.

1. Visual identification. At night, after the sky has completely darkened, close the curtains, try not to have any light into the room (the fabric in advance), the fabric containing fluorescent agent will have a bright light, this method is for the fabric with high fluorescent content.

2. Ultraviolet flashlight. Now the more commonly used method is to use an ultraviolet flashlight to irradiate, this detection method, if you use it for the first time, it is best to find a cloth that does not contain fluorescent agent for comparison, you will find that the cloth containing fluorescent agent is brighter.

3. Illumination of the money detector. If you have a money detector at home, you can also use that to take a photo, which is the same as the purpose of the ultraviolet flashlight, which is more convenient.

4. Specialized department testing. Go to the nearest quality inspection department for testing, preferably by selecting a few samples for testing before purchasing goods in large quantities.
