However, it is discharged into the environment in large quantities, or has potential effects on aquatic organisms. Studies have pointed out that at high concentrations, it may hinder the survival and reproduction of aquatic organisms such as fish.
Overall, 1-hydroxy-2 (1h) -pyridinethionato sodium is safe within the normal range of use. However, during use, it is still necessary to strictly abide by the specified dosage and use method to ensure safety and environmental protection.

1 - hydroxy - 2 (1h) -pyridinethionato sodium is sodium hydroxypyrithione, commonly known as Sodium Pyrithione (SPT). This substance is commonly found in the following products:
One of them is the shampoo and hair care category. Because of its excellent anti-dandruff antibacterial ability, it can effectively inhibit the growth of microorganisms such as Malassezia, which often cause itchy scalp and dandruff. In many well-known anti-dandruff shampoos, this ingredient is added to help people enjoy a refreshing and clean scalp environment, and their hair is more supple and shiny. For example, a professional anti-dandruff shampoo commonly found in the city uses the power of SPT to relieve dandruff worries for consumers.
The second is the category of personal care products. Such as body wash, soap, etc. SPT can not only antibacterial, but also prevent skin discomfort due to bacterial infestation and protect skin health. Like some body washes that focus on antibacterial skin care, after adding this ingredient, it can form an invisible protective barrier when cleansing the skin, resist bacterial invasion, and keep the skin fresh and comfortable for a long time.
The third is paint products. SPT has good anti-mildew and antibacterial properties. When added to the coating, it can significantly inhibit the growth of microorganisms such as mold and algae on the surface of the coating, prolong the service life of the coating, and maintain the appearance of the coating. Whether it is indoor wall paint or outdoor anti-corrosion paint, it can resist microbial erosion and make the paint surface last for a long time.
The fourth is the textile field. Adding SPT to the fabric finishing process can give the fabric antibacterial, deodorant and other functions. Especially for sportswear and close-fitting clothing, it can effectively inhibit the growth of bacteria, reduce the generation of odors, create a dry and comfortable feeling for the wearer, and improve the wearing experience.

Sodium 1-hydroxy-2 (1H) -pyrithione, commonly known as: omedine sodium, is a commonly used antibacterial agent in the fields of daily chemicals and medicine. When using this substance, all matters need to be paid attention to.
First, the concentration control must be accurate. Although this agent has good antibacterial properties, it may cause skin irritation and allergies if the concentration is too high. In daily chemicals, the concentration should usually be controlled within the safe range. For example, in cosmetics, it is generally not beyond the specified upper limit to ensure the antibacterial effect and protect the user's skin safety. If the concentration is improper, it will not only be beneficial, but also cause damage.
Second, the compatibility taboos must be clear. It can react with many metal ions, such as iron, copper, etc., resulting in reduced activity, and even precipitation, which loses its effectiveness. Therefore, when formulating, careful consideration should be given to the compatibility of raw materials related to metal ions, or appropriate chelating agents should be added to prevent adverse reactions. And it may also be incompatible with some anionic surfactants. When using, it is necessary to check the characteristics of raw materials to ensure the stability of the system.
Third, the use environment should not be ignored. High temperature and high humidity environment may affect its stability, accelerate decomposition and reduce antibacterial activity. When storing, it should be placed in a cool, dry place, away from direct sunlight and high temperature. If the temperature is not properly controlled during the production process, it will also have adverse effects on its activity.
Fourth, use with caution for specific groups of people. People with sensitive skin, pregnant women and children, etc., have more delicate skin or poor tolerance to the substance. When products are targeted at such groups, they must undergo strict safety evaluation, or choose milder alternatives to ensure safe use.
In short, when using 1-hydroxy-2 (1H) -pyrithione sodium, the concentration, compatibility, environment and applicable population need to be treated with caution, so that it can be used properly, exert its due effect, and ensure the safety of users.
