What is a fluorescent agent? Is it harmful to the human body?

Fluorescent brighteners are a class of organic compounds that can absorb ultraviolet light and excite incident light to produce blue or blue-violet light. It relies on optical action to whiten, brighten, or brighten an object, thereby increasing the whiteness and shine of the product. Fluorescent brighteners are divided into migratory fluorescent brighteners and non-migratory fluorescent brighteners.

Only migratory fluorescent brighteners can be transferred from objects to the human body through contact and pose a health hazard. There are many people on the Internet who buy their own highlighters to self-test fluorescents, but in fact, many things like fruit cottonseeds and the like also contain natural fluorescent substances, they are non-toxic but can also be detected by highlighters, so the results of this self-test with highlighters are not very accurate. It is recommended that if you are really worried, go to a professional testing institution for testing, or use those brands that have been tested by professional institutions, such as cotton times and the like, and you can also save money on buying highlighters.

I don't understand how to go down by myself.

Fluorescent agent, also known as fluorescent brightener, is a fluorescent dye.

1. Function: 1. It is used for whitening and brightening of various textile products.

2. It is used for synthetic detergent to increase the washing effect of detergent.

3. It is used for whitening of paper, improving the whiteness of paper and the value of goods.

4. It is used for whitening of plastics and increasing aesthetics.

2. Hazards: 1. Fluorescent agents are not as easy to decompose as general chemical components, but accumulate in the human body, producing many harmful effects and greatly reducing human immunity.

2. The fluorescent agent binds to the protein outside the wound and also hinders the healing of the wound.

3. Fluorescent agents can make human cells have a tendency to mutate, and their toxicity accumulates in the liver or other important organs, which will become a potential carcinogenic factor.

4. Cause damage to the blood system: chemical substances are easy to pollute the human blood, although the blood has a certain self-purification ability, a trace amount of harmful substances will be diluted, decomposed, suction and discharged, but long-term, a large number of toxic substances poured into, will cause qualitative changes.

5. When entering the blood circulation, it will destroy the cell membrane of red blood cells and cause hemolysis.

The harm of fluorescent agents to the human body is as follows:

1. Allergies: Some non-compliant skin care products can use fluorescent agents, long-term contact or a large number of contact with items with excessive fluorescent content may damage**cause**allergic reactions, such as itching, redness, swelling and even pimples, especially for children**delicate, more likely to have **problems;

2. Affect wound healing: some chemicals in fluorescent agents can combine with hemoglobin on the surface of the wound to hinder the formation of coagulation factors on the surface of the wound, which may affect the healing of the wound;

3. Affect liver and kidney function: some fluorescent agents can be excreted through human metabolism, and some fluorescent agents are not easy to decompose, and may accumulate in the body, and long-term accumulation in the liver and kidney may lead to the decomposition and excretion function of the liver and kidney, affect the body's metabolism, and in severe cases, may affect the circulation disorder in the body, and even destroy the formation of immunoglobulins, which will affect the immune function;

4. Affect the blood system: long-term and large exposure to fluorescent agents may cause harmful chemicals to enter the human body through **, mucous membranes and other parts, thereby entering the blood circulation, damaging the red blood cell membrane to a certain extent, and easily leading to hemolysis symptoms.

Detection methods for fluorescent agents

1. If there is a money detector lamp at home, you can use the money detector lamp to shine a light on the items that need to be detected in a dark environment, such as baby's underwear supplies, if it shows purple, it is not added fluorescent, and if it turns blue, it is added with fluorescent.

2. The more common detection method is to use an ultraviolet flashlight for irradiation, and it is necessary to try to operate in a room where no other light enters. If this detection method is used for the first time, it is best to find a piece of cloth that does not contain fluorescent agent for comparison, and you will find that the cloth containing fluorescent agent is brighter.

3. Professional and technical testing: the detection of fluorescent agents can also be detected by CPPO fluorescence experiments, and the specific types of detection include mass spectrometry and infrared spectroscopy, which requires professional instruments and personnel for testing.
