2(1H)-pyridinethione, 1-hydroxy-, sodium salt (1:1)

2% 281H% 29 - pyridinethione, 1 - hydroxy -, sodium salt (1:1), that is, 1 - hydroxy - 2 (1H) - sodium pyridinethione, this is a white to light yellow crystalline powder, used in many fields.
Its solubility is quite unique, easily soluble in water, this property makes it easy to disperse and mix in aqueous systems, providing many conveniences for its application. For example, as a preservative in cosmetics, it can be evenly distributed in the product.
It also has excellent antibacterial properties and has significant inhibitory effects on a variety of bacteria and fungi. Like in the paint industry, it can effectively prevent the growth of microorganisms, prolong the service life of coatings, and ensure the stability of their performance.
In terms of chemical stability, it can remain stable under conventional conditions. However, when exposed to strong acids and alkalis, chemical reactions may occur, resulting in changes in structure and performance.
In terms of safety, it is relatively safe for the human body within the specified range of use. However, if the contact amount is too high, it may cause irritation to the skin and eyes. When applying cosmetics, strictly follow the use standards to ensure the safety of consumers. < Br >
1-Hydroxy-2 (1H) -pyrithione sodium plays an important role in industrial, daily chemical and other fields due to its unique chemical properties, providing strong support for the performance improvement and quality assurance of related products.

1-Hydroxy-2 (1H) -pyrithione sodium salt (1:1), often referred to by its English abbreviation OCS, is used in many products.
In personal care products, this substance is commonly found in shampoo products. Because of its excellent antibacterial and antifungal effects, it can effectively inhibit the growth of microorganisms such as Malassezia, which often cause dandruff and itchy scalp. It is used as a key active ingredient in many anti-dandruff shampoos to maintain the balance of microbial flora in the scalp and achieve the purpose of anti-dandruff and anti-itching.
In the field of coatings, 1-hydroxy-2 (1H) -pyrithione sodium salt also has important uses. Coatings are susceptible to microbial erosion and deterioration during storage and use. Adding this substance can effectively inhibit the growth of bacteria, molds and other microorganisms by virtue of its antibacterial properties, ensure the stability and quality of coatings, and prolong their service life. At the same time, in some external anti-mildew and antibacterial coatings, it can also play a role in making the coated surface have the ability to resist the growth of mold and maintain the appearance and performance.
In industrial circulating water systems, this sodium salt can be used as a fungicide. Long-term operation of circulating water is suitable for microbial reproduction, which can cause problems such as pipeline corrosion and blockage. 1-Hydroxy-2 (1H) -pyrithione sodium salt can effectively kill bacteria, fungi and algae in water, control the number of microorganisms, ensure the normal operation of circulating water system, and reduce equipment failure and maintenance costs caused by microbial problems.

Sodium 1-hydroxy-2 (1H) -pyrithione, the effect of this substance on human health is related to many aspects.
In daily products, such as shampoo and conditioner, sodium 1-hydroxy-2 (1H) -pyrithione is often used as an anti-dandruff ingredient. When used in moderation, it can effectively suppress scalp fungus, anti-dandruff and relieve itching, make the scalp environment healthy, and the hair should be nourished, supple and shiny.
However, if excessive contact, it may be unfavorable. Those with sensitive skin, or contact dermatitis, present with erythema, itching, and tingling. Due to the different tolerance of individual skin, sensitive skin has weak defense and is easy to be irritated by it.
And oral ingestion is also risky. If you take products containing this ingredient by mistake, it may disturb the digestive system and cause nausea, vomiting, and abdominal pain. Because it is metabolized in the body or affects the function of organs, it affects the liver and kidneys, and it will hurt for a long time.
Inhaling its dust can also damage the respiratory tract. It can cause cough, asthma, poor breathing, and even induce respiratory diseases such as asthma, especially for people with fragile respiratory tracts, which is even more harmful. Therefore, when using a product containing 1-hydroxy-2 (1H) -pyrithione sodium, use it moderately according to the instructions to avoid excessive contact to protect human health and prevent its harm.

2% 281H% 29 - pyridinethione% 2C + 1 - hydroxy -% 2C sodium salt% 281% 3A1% 29 is the sodium salt of 1 - hydroxy - 2 (1H) - pyridinethione. The preparation process is as follows:
First, 2 - chloropyridine is used as the starting material. 2 - chloropyridine and sodium hydroxide solution are mixed in a reactor. The two are like the two armies of the ancient battlefield. Under a certain temperature and pressure, a fierce "confrontation" occurs, and a nucleophilic substitution reaction occurs. In this process, the chlorine atom is replaced by a hydroxyl group to form 2 - hydroxypyridine. This step is like building the cornerstone of a pavilion, which is crucial.
Then, 2-hydroxypyridine, sodium sulfide and sulfur are placed in the reaction vessel and heated. Just like alchemy in a furnace, under specific reaction conditions, the three interact to vulcanize and generate 1-hydroxy- 2 (1H) -pyrithione. The formation of this substance is a key turning point in the preparation process.
Finally, 1-hydroxy-2 (1H) -pyrithione is mixed with sodium hydroxide solution in an appropriate ratio to undergo acid-base neutralization reaction to obtain 1-hydroxy-2 (1H) -pyrithione sodium salt. This step is like cutting a sword to make the product final.
The whole preparation process needs to be carefully controlled by many factors such as reaction temperature, pressure, material ratio and reaction time. A slight mismatch is like a misstep in marching, which affects the purity and yield of the product. In this way, qualified 1-hydroxy-2 (1H) -pyrithione sodium salt products can be obtained.

1-Hydroxy-2 (1H) -pyrithione sodium salt (1:1), known as omedine sodium, has considerable prospects in daily use, medicine, and agriculture.
In the field of daily use, it is often found in shampoo and hair care products. Because it has the effect of inhibiting microorganisms such as Malassezia, it can effectively relieve dandruff problems and help the ecological balance of the scalp. Many anti-dandruff shampoos use it as a key ingredient, which is favored by consumers. In skin care products, it can also prevent skin infections and maintain skin health by virtue of its antibacterial properties. It is widely used in acne and oil control skin care products.
In the field of medicine, with the dual effects of antibacterial and anti-inflammatory, it plays a role in the treatment of skin diseases. For diseases caused by fungi such as seborrheic dermatitis and tinea versicolor, it can inhibit fungal growth and reduce inflammatory response. It is often used as an ingredient in external drugs to relieve pain for patients. And its safety is high and it has a wide range of applications.
In the agricultural field, it can be used as an excellent fungicide. It has a significant control effect on a variety of agricultural diseases, such as wheat rust and cucumber powdery mildew. By inhibiting the growth of pathogenic bacteria, reducing the incidence of diseases, ensuring crop yield and quality, and helping agricultural harvest. At the same time, it degrades quickly in the environment, has less residue, is friendly to the ecological environment, and meets the current needs of green agriculture development.
In summary, 1-hydroxy-2 (1H) -pyrithione sodium salt has a bright future in various fields. With technological progress and in-depth research, it is expected to expand more application spaces.
